Customer's reviews and ratings:
I need to convert a large .ost file to a .pst file to set up a new laptop. Recovery Toolbox worked very well and relatively quickly.
My Outlook PST files (30+GB) were still accessible but running off a hard-drive that had started to fail with bad sectors. I was unable to clone the drive or copy the PST files to a new location. Recovery toolbox was able to rebuild my data files as a new data file on a replacement drive location and continue to use my mail file after the recovery process. Tried many other recommended solutions but none were able to help with the recovery apart from the recovery toolbox for outlook.
the file I was trying to repair, had nothing wrong. Simply I wrongly backed-up my old e-mail history in a .ost file instead of a .pst file, and I needed to check some of the e-mails contained in that file. Your program worked fantastic, and I successfully converted the .ost into .pst having back my old e-mails. Thank you very much.
My PST got corrupted as it grew too large. Windows Explorer showed a size og 76gb, the recovered files is 50GB. I will still have to verifiy if everything has been recovered.
When changing my ISP to gmail I created a new ost file leaving an orphaned ost with past information which i wanted. Recovery Tollbox allowed me to convert and then retrive this
The OST files were not corrupted. My client got a system where the M465 mailbox was closed and the only access to old emails was from a local OST file on the same system. Outlook was reporting that it could not connect to the exchange server, but the 11GB OSt file was still there. Using Recovery Toolbox, we were able to create a PST file and access all the old emails.
This was the only utility that quickly solved the problem of converting OST file to Outlook PST file. Thank you!
My Outlook.pst became corrupted. Why? I have no freaking idea! This has happened several times and the hassle to get it back was time consuming and worrisome because I thought I lost all my contacts and calendar. In using Recovery Toolbox for Outlook, I have all my mail files on my C drive but I have my Outlook.pst file on my Google drive. I think that was the problem. So what I did was use Recovery Toolbox to fix my Outlook.pst file, move it to the subdirectory where the mail files are and it worked. I am so grateful and the price is excellent!!!
I really appreciate your app because it solved my problem. I just had to convert the OST file. Tanks and regards
In the west, nothing new, nothing to do, even Microsoft is incapable; someone had put me before September 7 and it showed right away, 16 viruses erased by Microsoft's free scanner, but the damaged pst file, we can't find which one and I read my mail on my email, stella is no better, even worse. Finally, your presentation of all the psts is fine, but which one is bad? mystery....
I accidentally erased 3 months of Inbox email by clicking on the "Empty Folder" button. As part of my PC management, I backup my C Drive incrementally every night and that includes the OST and PST Outlook files. The backup copy of the PST file was missing 3 months of emails while the OST still had them but inaccessible. So, your program converted the OST to a new PST and I could recover the lost emails. Great Program, thanks.
My Outlook .OST file "lost" 99% of my Inbox, although subfolders were fine. There was a "restore point' created just before the issue so I think O365 made a mess of an upgrade. Outlook could "open" the (much larger) restored file but promptly deleted the same files :( Recovery Toolbox was able to convert the back-up of the OST file to a .PST file which I could attach and extract the missing emails :) Great job, great software, saved my mail!
The user said that Outlook 2019 hung and then crashed and then wouldn't open. We found that we had to detach his PST file from Outlook. The PST is 6GB in size. We ran SCANPST against it but it wouldn't repair. We used your tool and it repaired the PST to where we could attach it to Outlook again. Thanks,
My hosted Exchange mailbox got corrupted by moving too many mails too fast in the local Outlook. Toolbox was able to restore the missing items from the daily backup ost. Some manual work needed to move the recovered items from the new substructure to the original (in my case less than 100 at the time, then wait for the folder to synchronize)
Simple to use and effective
No file was damaged but without your toolbox it was not possible to convert the (huge) ost file into a pst file.
With pleasure I purchased your software/tool; Because of foldernames and mail locations in my client (Outlook 2016) became corrupted I decided to freshly install Outlook. As I locally had only the .ost files I decided to purchase your tool; so I could convert these to .pst files that can be imported in Outlook. Your tool makes doing so just a breeze. Thank you.
I switched ISPs and during that process ended up with an .ost file that I could not import into Outlook. The ost file contained hundreds of emails that I needed for work. Using the Recovery Toolbox software, I was able to convert the ost to pst and then load into Outlook. Great tool. Thanks, Keith
With outlook was imposible to convert my ost file to pst, but with this program can recovery my files but the problem my files are not in the same structure
I tried to install Outlook 2021, bought from the MS site. Unfortunately it was unsuccessful. Stating that my existing outlook (2010) data file is corrupt. Your software fixing the data file.
I had a large ost file of about 20GB on an imap account that no longer existed. I needed the data converted to pst format. Tried various exports of the data using Outlook but they all failed. The recovery tool converted the entire file to a pst with no loss of data. Exactly what I needed.
Advantages: 1. fast program. 2. Reads everything. Good preview. Disadvantages: 1. Needs Outlook not version 365 2. Needs Windows
My source files were not damaged. Due to issues with outlook, I had to remove my outlook email address and re-add it. Before deleting the email address I copied the .ost file. I used the recovery software to convert the copied .ost file to a .pst file and added the .pst file as a datafile in outlook.
They weren't damaged. Rackspace had a severe Exchange outage (Google it!) and so we are trying to convert from OST to PST so we can move to O365.
The original OST file was not affected. I wanted to recover an old email account that could only be found in the ost file. And so it had to be converted to a PST file and opened in Outlook.
The Exchange service we were using stopped functioning. When switching to a new service I didn't convert my .ost to a .pst. Which I subsequently did with Recovery Toolbox, excellent tool. I learned a lot about cache files.... like the ost doesn't contain mail older than a year by default. Which I can see in your logger before doing the conversion. So I'm still missing 18 months of mail and hoping I will eventually get it back from the Exchange service. Now having trouble re-integrating the autofill file.dat in the Cache folder as I see that's separate. Greg
Everything recovered as if it were magic! It's good to have something that solves like this
I hired a tech from my local Wired office who tells me that the files were probably damaged during a M/S update. He says he "has never seen this problem before", uninstalled the entire Office suite after trying all other options and the problem persisted. Since I ceded control of my computer to him, I am not sure how he proceeded from there but he did eventually fix it. Thankfully, his costs are reasonable.
One Outlook PST file repeatedly asked for password but didn't accept the password that I typed. I hadn't forgotten the pw and I absolutely know that I was typing it correctly. I tried the MS pst repair tool and some other free tools and then some that do a "teaser" recovery of a few items per folder. This tool recovered the content of the pst. The downside is that it didn't actually recreate the pst, it just recovered the content. The folders were recovered but not the folder structure, nor were the calendar entries recovered correctly particularly those with recurrences. To be honest, I am just grateful to have all the data back available to me and there appears to be nothing missing. Thank you for an excellent 99% product.
I reformatted my computer. The .PST did not get backed up in my incremental backup since Microsoft does not change the modified date of it unless you disconnect from Outlook. I used the recovery tool to get a .OST from the backup and convert it to a .PST - just what I needed!
Value software to convert ost to pst.
Hi, I lost SENT ITEMS folder from my Outlook 2016 Inbox, it appears that I did something wrong with my mobile Outlook Client (Android) that made this happen, so synchronization ocurred with my Godaddy e-mail hosting and SENT ITEMS were fully deleted from my Outlook Laptop Client. I tried to recover these emails from my Laptop computer, but recovery was only partial, some of them were successfully recovered, others not... I recovered only about 20% of the emails. Thanks...!!!
We decided to license Recovery Toolbox software for converting .OST to .PST files from some officers who have retired from Microsoft 365 licensing. Additionally, it allowed us to recover PST files that could not be opened and used from Outlook. Very good tool!!
Taking to long for PST conversion. Still Pending. More than 12 hrs.
No recovery needed, just converting an old Hosted Exchange domain mailbox from OST to PST to move into the customers new domain O365 setup. Worked perfectly and was really fast. Took about 30 mins for a 15GB OST file to convert to PST.
fast and convenient service for converting Outlook mail
Easy to convert 5.6Gb Exchange Server .OST file. Thanks!
I was allowed to take a corporate large pst file and fix it at home on my pc. I thought it would take 2 days since the file size is 48 GB !! But the program fixed the inaccessible file in less than 3 hours.
I tried to fix errors in the file by use SСANPST.exe, but it didn't help. Recovery Toolbox for Outlook was able to get letters and contacts from the pst file.
Thanks for helping to repair corrupted Outlook 2003 .pst file.
Fine. I was able to wait for the complete synchronization of the .OST file, and then converted it to .PST. The file size came out approximately 34GB. Everything went fine, I was able to retrieve all my letters.
Thank you.
Many thanks for the support in restoring my mail. Thanks for the work you've done.
I could fixed Microsoft Outlook 2003 .pst file with all contacts. Out of 249 letters, 7 letters were repaired without content.
God, what a program! Converted .ost to .pst, and also got offline access to the account. Super!
I haven't used Outlook for several years. There was an attachment to an old Outlook email that I needed to find and retrieve. That's what I used your software for.
I cant open the .pst file even after repairing, Outlook said "outlook.pst is not an Outlook data file". If you have the same problem, write to the support, they sent me step-by-step instructions, after which everything started and everything works
I downloaded the program, installed and repaired the .pst file. But without an Outlook client, the fixed file won't opening. I will supplement the review when I look at the contents of the file at work.
After system restore (Windows 7), I had to deal with troubleshooting the missing Outlook messages. I had a .PST file, but the fallback system caused emails to be deleted. It took less than a minute to fix the .pst file (online), the service recovered the deleted messages.
My address book became complete again, I fixed the damaged file and got my contacts and letters back.
The goal is to restoring MS Outlook contact history, and as a result, both contacts and deleted messages were undeleted. Twice happy!
The program repaired all information about my tasks from a corrupted Outlook 2007 .pst file. Now I can export all data to Outlook 2019.
I bought Recovery Toolbox for Outlook to recover mail, but I cannot find the .pst file. I called support, they told me to download their free utility "Mail Undelete Recovery Toolbox Free", which eventually helped me restore the folder with lost letters and contacts. I am very grateful for the help, they said that the money will be returned within 10 days. thks
Damn such a stupid mistake, while restoring, I somehow unchecked the "Outbox" letters. As a result, in Outlook, I saw only the contents of the Inbox messages. Only after a second "thorough" recovery, I was able to recover all the contents of the mail correctly. P.S if you see the letter, please excuse the angry statement)
I don't know why there is a converter here, because Outlook already stores all letters in .PST. I selected letters from the email, pressed the "recover" button and received all the letters. The program is definitely needed, while I used it once.
Damn guys, you are super!! I no longer hoped to find a program for repairing Outlook emails, especially for Vista operating system. The accountant asked to try your product and it worked!! We were able to export all emails from corrupted .PST file and open them in Outlook 2007 Today, I'll ask Boss to write a check for the new Windows 10 operating system! Guys, you know your business!
I usually use the native Microsoft Outlook utility (Scanpst.exe) to fix errors, but today I first encountered such a problem, the utility crashed. Work colleagues have recommended your program. The program really helped repair contacts and emails from a damaged .pst Outlook file, but for me it is a little more complicated than the native tool
Yesterday I licensed a low cost solution and my problem is behind me now. I wish you and your company the best….Chuk
I think I have gotten it recovered. I uninstalled outlook 2010 32 bit and installed outlook 2010 64 bit. I was going to then run the recoverytoolbox program but when I clicked on my newly installed outlook it found my data file. I am still confused as to what happened but I am back to work. Thanks, Dennis
Thank you for producing such an excellent application. I have accomplished many things. Thanks... Thanks... Thanks...
Had a few problems running it initially but great tech support helped fix my oversized pst file.
It run well and I solve my issue. Many Thanks. Olivier
Plus: I've converted 11Gb OST file. Minus: Price is expencive $50. And I've wait 7 hours.
Plus: 1) Can try before you buy, make sure anti-virus is happy, that it finds and fixes corrupted files. It will then fix 5 files per folder for free or pay for the rest. So you can make sure it will work for you before paying. 2) Can work with Outlook x64 Minus: Not free.
My .pst files were restored, that's all I needed. Tool deserved to be used, at least one time, to see it in action...
Tool restored my dozen corrupted emails after unexpected switch off my computer. Design might be a little better One of best tools I've ever used for damaged .pst files
I've lost many outlook messages this morning. Tool restored them about some hours ago. Effective tool for MS outlook 2010.
Tool forced me to forget about lost .pst files of Microsoft Outlook 2003. I chose it and was lucky.
Tool makes own business very well. Sometimes tool suspend my computer for a little time. I bought it, and it's one of the best products which I have been ever seen.
Software handled my trouble with crashed Outlook 2007 emails after turning my computer off. I acquired this tool for some minutes, during the same time it solved my issue.
Software for some minutes found out crashed MS Outlook emails and got me back data. Tool needs a lot of resources of hardware for its working. In result, most of corrupted emails were restored, I'm almost glad, almost.
My Outlook 2003 emails were fully restored. High requirements of product, especially under working with huge email messages. My machine is on a ledge of cancel. Positive solution, but not for old computers.
Plus: Easy to use. Relatively inexpensive. Completely restored an intact OST file. Minus: None for me. I don't know whether it works on a corrupted file. SUMMARY: I lost an MS Small Business Server (2008) in a storm. Most of the users were using cached Exchange mode in Outlook, and I was able to open Outlook and copy their existing folders to a PST file. I forgot a couple of folders on one PC (Outlook 2007), though, and I lost access to the OST file after joining the PC to the rebuilt domain. I downloaded the demo copy of Recovery Toolbox for Outlook onto my laptop and used it to examine the OST file. It successfully recovered five items from each folder in the file, so I purchased a licence. Got the email with my license key within about five minutes, applied it to the program and recovered the entire OST file a couple of minutes later. No problems, and the user was happy! I have not tried this on a corrupted OST or PST file, so I can't speak to how well it works on those. But on an intact OST file that you cannot open in Outlook, it worked like a charm. Plus, it cost a lot less than some other recovery programs.
PLUS: The software was able to recover an .ost file that was created using Outlook 2010 and Outlook Connector_v14.1. The scanned happend quick for a file under 500MB. The price of the software is well worth it to recover a .ost file!! Offer: I haven't come across any problems with this program, I only just used it like an hour ago. This con is more towards MS and Outlook 2010, if you create a program that uses a file (.ost) that program should be able to open it and be used like before. Total: If you use MS Outlook 2003, 2007, 2010 this program will help you recover .pst and .ost files! The price is great and to this work the first time out. Even thought some of the data was missing, but I think that is more because of MS Outlook .ost file (local file) did not have saved in it. If you need to get calendars, contacts (root level), deleted items, drafts, Inbox (email), Journal (only if the .ost has it in it), Junk Email, and Sent Items then this program is for you! If your using Outlook 2007, 2010 and the plug-in "Outlook Connector" there are 3 folders that this program MIGHT not be able to recover. Any folder in Outlook with the following after the folder name: This is because you have an Hotmail/Windows Live email account and your are using Outlook's plug-in "Outlook Connector". It just goes to show you MS Office Outlook 2010 is still lacking in basic software usability to import a .ost file. Thanks Microsoft way to drop the ball yet again.
Price is very reasonable compared to other programs written to do the same thing. Works to extract data from pst files and also ost files. Many of the other programs will only do pst files. Scanner is slow. Even on a fast computer it can take 1 hour to read the contents of a 2 Gb size file. And then take 3-4 hours to write the contents to a new pst file. I have used the program for 3 years. I needed an ost recovery program and a review of internet indicated that most of the progrmas that would do this started at $300 for a 1 time use. Over the 3 years that I used this program it has paid for itself many times over. If I need to fix someones file I will take the file to my home shop and run the program on a quad core system over night. Recently I was unable to recover a file with this program and so I purchased a more expensive program. The new program ran faster and worked better. However,the new program would only repair pst files, it would not read ost files. So I now use both programs. This program to recover ost files and the other one to recover pst files. For anyone needing to repair pst or ost files this is the place to start. Most of the other programs available that have been written are much more expensive.
