Recovery Toolbox for CD Free:

Greetings with my best regards for your continued success!

There are certain experiences so rare for some of us, we discount them as ever being in our past, present or future. Then one day, it's our turn, as is my case of a damaged DVD that is suddenly unreadable. It's only one DVD I am not inclined to purchase software for, so I looked for a freeware option.

Your Recovery Toolbox is what I first found as suitable and will try, but will inform you after of the outcomes.

Good-day!

Yazid Hariz 03-25-2024

It has been damaged when zipping the file. it's a video from Iphone.

Maurizio V. 03-21-2024

Grandioso, mi ha risolto il problema. Avevo un file .VOB su un DVD che nessun programma mi riusciva a leggere: lui invece ci è riuscito, così adesso mi sposterò tutti i files e potrò poi vedermi tutto il video sul SSD del computer.

Amrish 03-17-2024

Awesome product, life saver for me.

Pat 03-16-2024

Fully recovered a file I have been struggling to retrieve from a CD that had lost its date stamp etc, It took a few hours but in the end I have the file.
Brilliant piece of software

Ray 03-15-2024

Excellent pgm. I can't thank you enough for allowing me to use your product.
It works effortlessly, like a dream.
I was at my wits end, I had all these irreplaceable pics from various overseas trips, and the recovery disk could not open them.
So once again, many, many thanks and all the very best to you and the team for the future.

AlGood 03-15-2024

This program found a lot of hidden in PST file. Many pieces of data and requires additional analysis.

Ирина 03-14-2024

About half of the file was recovered. Also good, of course, but I was counting on a complete recovery.

Great

Daniele 03-07-2024

Scenario: large Excel file not saved elsewhere and costing hours of work. The file becomes damaged for unknown reasons. After trying a few manual systems to no avail, I tried RecoveryToolbox and since the data seemed to be read correctly, after 10 minutes I purchased it. Great software that worked very well in my case.

VIJAY YADAV 03-05-2024

great tool. It Works Excellent.

Kevin Clawson 03-01-2024

This is long story... here is short story. Windows 11 (22HC) issue that kept crashing. 95% then 'Something went wrong and we are resetting it back' message.
This got up to Level 2 Tech on third day, who then forced a Re-Install Windows 11 to (23HC) since would not get past the 22HC update 'pending'/crashing. Once he forced the downloaded and got it started on to my computer, I finished the re-install. (About an hour and half) When he called back, it was done. Asked him to help me with OUTLOOK 365 Corrupted Profile issue.

After he was done, setting up a new profile and all the heath check verifies everything seemed fine. However the next day, my contacts file was empty.
OUTLOOK 365 would not allow me to use any of several backup .pst files. Thought password was causing the problem.

I was able to get them up a few minutes ago by switching back and forth to original and new profiles. I hope the corrupted profile issues are still good now. (to be determined)

Used your program on backup.pst file and program appears to be working fine !! Very sorry for not trying all this first.

Because the source file only changed the opening method so that a certain part of the file was updated, after changing to the correct application again, the file showed "File truncated". I think the source file has not changed much, but because the source file itself is relatively large (1.4G), the recovery process is too long, so you can try to optimize it.

Steve Powell 01-25-2024

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.

Jordi 01-25-2024

The zip file was damaged and I don'k know why. It has been already recovered, but the problem was that, after testing it with your demo, I bought the license and after register the software with your license, it was required to reboot the software, so I had to start again the recovery.
As a computer's technical and adivsor, I'm user of a lot of software for several works and always use a demo before purchasing the license (if it looks that works, of course), and from the demos version, after registering the license, it is not required to reboot the software, so I can continue with the data recovery (or whatever it needed) without loosing the time invested in checking the software. In your case, I had to start again the recovery, so it means that I loost a lot of time because of the need of restart your software after registering the purchased license.
So I guess that it would be interesting change this behaviour of your software after buying the license in demo cases. Best regards, Jordi

Steve 12-12-2023

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.

Stefano Benaglia 12-11-2023

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.

edrees 12-07-2023

we faced a database crash because of an electricity failure and this tool was very grate

Sam 12-05-2023

Two Windows workstations were logged in to a small but critical Access database, one using Office 2007 and the other Office 365 local. There was a power outage and UPSs died before PCs could be logged out properly. After power was restored none of the tools provided by Microsoft could recover the corrupted accdb file. Thankfully RT got everything back, and UPSs all have nice fresh batteries now.

François Steies 11-30-2023

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.

Paul Buiteman 11-27-2023

I have a crashed hosting platform and try to recover 5 WordPress websites. I was able to download all the data.
4 WordPress databases are recovered, the software works great.

Marcos Campos 11-20-2023

I had my database encrypted by RamsomWare.
Using the recoverytoolbox application I was able to access the table structure, but the most important tables are corrupt.

Some tables were complete.

Rog 11-15-2023

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

Geordie 11-03-2023

The OST files were not damaged. My client was given a system where the M465 mailbox was locked and the only access to old emails was from a local OST file on one system. Outlook was reporting that it could not connect to the exchange server, but the 11 GB OSt file was still there. Using Recovery Toolbox, we were able to create a PST file and access all old messages.

JohnJJ 11-03-2023

This was the only utility that quickly solved the problem of converting OST file to Outlook PST file.
Thank you!

Albert H 10-27-2023

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!!!

Marco Costa 10-27-2023

I really appreciate your app because it solved my problem. I just had to convert the OST file. Tanks and regards

bgarrard 09-18-2023

I had a strange issue and a different repair utility said that I had 4 records with an invalid delete flag. I could see the four records, but they were blank in every field. I recreated the 4 records but then the application thought they were now duplicates. Packing and copying to an empty table did not help. Your utility solved the invalid delete flag, but all 4 records were gone so I recreated the 4 records again. Now everything seems to be fine.

Gabrielle 33 09-14-2023

In the West, nothing new, nothing to do, even Microsoft is incapable; someone had put me before September 7 and it was seen immediately, 16 viruses erased by the free Microsoft scanner, but the PST file damaged, we can't find which one and I read my mail on my email , stella is not better, even worse. Finally your presentation of all the pst is good, but which one is bad? , mystery....

Jim 08-08-2023

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.

Mojtaba Moradi 08-05-2023

The source files was changed because of a Ransomware attack

Derek 07-04-2023

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!

Eric 07-01-2023

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,

Arturo 05-24-2023

Highly recommended software, recover lost outlook pst file password very quickly and 100% recover.

Karl 05-24-2023

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)

Andrea 05-17-2023

Simple to use and effective

Manfred Pitz 05-15-2023

No file was damaged but without your toolbox it was not possible to convert the (huge) ost file into a pst file.

Yuri Versteeg 05-09-2023

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.

Keith Croteau 04-24-2023

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

Sergio Hugo Ramírez pacas 04-17-2023

Excelente programa recupere información de 42 GB de un archivo pst de Outlook, lo único malo tal vez que los programas de antivirus lo reconocen como un ataque y tuve que desistalar el programa una vez que rescate la información ya que se crea una incertidumbre por el software, pero de ahí en más es un excelente programa

Arturo Gutierrez 04-17-2023

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

Robert Delmenico 03-27-2023

Not sure how the source .pst was damaged.
I save my .pst files on a portable hard drive so I can use on different computers.

I use office 365 and have a very low regard for MS outlook. It could have been anything that caused it.
Outlook seems to hang from time to time when I am using it and it might have become corrupted during that.
