About myself:
My name is Roberto, I am a computer forensics professional working independently since 2008. I live in Chile, close to Colina in the Regin Metropolitana.
As a forensic investigator working for many many different customers and for the sake of their privacy, I maintain a low profile with no web site and a typical gmail email account.
About my use of DataNumen products:
I choose Outlook Repair and Exchange Recovery from DataNumen as the best tools to fit a step in the process of doing forensics analyses of emails.
In practice when dealing with dozens of PST or OST files, it is not uncommon to stumble into files that had a certain degree of internal
corruption, and of course they also hold deleted emails that should be recovered for the analysis to be as complete as possible. So now, whenever I have to process those kinds of email files, the first mandatory step is to run them through DataNumen software to get a "fixed" set. Very nice that DataNumen can do batch processing. Load all files once and run. In a high performance machine with 32GB Ram and 2x 2TB of M.2 storage, this can require from one to three days non stop, depending on the case. Too bad DataNumen software does not use all machine cores to speed up things, but now they placed this idea into their request list. Once done, I create a forensic image with the fixed files, and then proceed to digest that image with X-Ways Forensics, my forensic tool of choice.
Outlook got fouled up, right after a Windows update my Email program Outlook stopped working. I used datanumen product to rearrange the email folders properly and it worked. All I had to do was run the program to fix the data, changed the data file name and run Outlook. Presto it worked. Many thanks
I was using another program to sync my outlook (Companion Link) and my phone and the program malfunctioned and wiped my newer data on my computer with the older data from my phone. I didn't have a backup of the outlook file and I was so frustrated to lose very important updates to notes. I spent pretty much all of a couple days thinking and figuring out a way to fix this through every method possible (previous versions, other recovery software, other online tips) and it seemed impossible, but luckily found the Datanumen product and was able to repair/recover the lost notes! With being a small business and going through some of life's difficult times I was extremely down, sad, angry when I thought my outlook data was overwritten by that error and frustrated with no way to get it back and was extremely pleased to find this Datanumen program and have it work to restore my data, it's amazing and the software was intuitive and easy to use. This is such a great company and just wanted to let everyone know they make a difference in peoples lives for the better!!!
This message serves as a BIG THANK YOU for your brilliant Outlook repair tool. My customer had been experiencing multiple power outages which caused Outlook pst to become corrupt. Scanpst came up with error referring to disk problems. I googled this error and luckily stumbled upon your product. I installed and ran the tool which took over 2 hours to complete. The end result was a perfectly working Outlook which was much faster than before! My customer is over the moon as it is a business account relying heavily on email.
MS Office upgrade crashed my computer and I had to delete and reinstall. In the process Outlook did not accept the old .ost file and I lost all my emails stored in sub-folders (local computer only). This is a failure on behalf of Outlook, not to re- create the sub-folders on the server. After 6 hours of panic, I found your site and downloaded the software, less than 30 minutes later all was good again.All emails safe and accessible.
I downloaded your outlook repair software because of constant error messages about my outlook.pst file having not closed properly on last use. You software worked perfectly. My pst file grew from 1.9gb to 2.45gm with 'lost data' that had been recovered and thoughtfully placed into two 'recovered' folders (not just dumped in the in box) for me to browse. It took less than 10 minutes for a complete recovery and scan of the recovered mail items.
A really great piece of software that is super thorough and and delves deep to find deleted and lost emails. I managed to recover an eminence amount of information that no other software that I used could. I really appreciated being able to use this application privately at no cost.
This software is extremely good. I am really thankful to you for providing such an important tool (DataNumen Outlook Repair v 1.2 full version) for public use. Let me know if you could provide the tools some thing beyond this.
I received the DVDRom with the zipped pst-file. I have been able to extract it and all is working well again.I wish to thank you for the kind an splendid support and all the help you have given me. If it wasn't for you and AOR I probably wouldn't have recovered the data in the file.Kind regards,
Its it possible to specify the location and name of each file in the Batch Repair tab? This is already possible in the Repair tab, when only processing one file, but it would be really usefull if it were possible to edit the output file details in batch repair.
Time ago I buy Datanumen Outlook Repair and I am happy with it, using it form time to time. Now I need to recover deleted emails from a bunch of NSF Lotus Notes file. I thought you might have a good product but alas you dont have anything for Lotus Notes. Well, since you do things right, why not a Datanumen NSF Repair? Best regards, Roberto
I just wanted to say Thank You for the software.
My Outlook data file appears to be mostly fixed.
I needed to inspect and delete a ton of entries but, I think, I recovered most of my data.
I will never know what I have lost permanently!
Advanced Outlook Repair completely repaired a 19GB Outlook 2007 .pst with multiple folders from over 15 years. It became corrupted after a hard shutdown, and would not open, even in safe mode. I heard about your tool from "chcw" on ExpertsExchange.com and from the repair percentages comparison table between tools on the Datanumen.site. I had made a copy of the .pst, and tried with no luck with the Microsoft scanpst.exe. 3rd party tools had helped years ago with Outlook Express conversion so I looked online. Advanced Outlook Repair was the only one getting affirmative positive reviews for complicated cases, and they showed examples of such, so I found a coupon and bought it. The first pass said the original file was held open by another source (even though rebooted). I next tried it against the copy, and within minutes (about 20%), my Outlook popped open - with complete up to date folders and emails. It scared me because I thought I had touched something and shut it. A few minutes later, that
DataNumen Outlook Repair automatically saves the recovered data into a brand-new PST file xxxx_fixed.pst, where xxxx represents the name of the source PST file. For example, Outlook_fixed.pst would be the fixed file name if Outlook is the name of your source file. However, you can rename the fixed file if you would like to:
The entire hierarchy for the file will be rebuilt for the fixed file so that emails and other objects will be placed in their original folders. Lost & found objects will be put in folders named Recovered_Groupxxx.
PST(Personal Storage Table) file is also called Personal Folders File. It is a kind of Outlook data file. Outlook uses it to store Outlook email messages and other mailbox items for pop3 email accounts, such as Outlook.com or hotmail.com. Our Outlook recovery tool is mainly designed to repair corrupt PST data files.
PST files have two variants, i.e., Unicode format and ANSI format. Our tool supports both formats. And can convert between these two formats when necessary. ANSI format has 2GB size limit. So Outlook 2003 and higher versions all use Unicode format. We also recommend you to convert all existing PST files to Unicode format, unless you are still using Outlook versions lower than 2003.
OST file(Offline Storage Table) is also called Offline Folders File. It is another kind of Outlook data file. Microsoft Outlook uses it to store data for email accounts other than pop3, such as accounts on Microsoft Exchange servers.
Yes, our Outlook recovery software can repair OST files. You can also use DataNumen Exchange Recovery to do the task, as DataNumen Exchange Recovery is mainly designed for OST file data recovery. It can also convert OST to PST files when the Exchange server crashes or is unavailable.
There are many reasons that will lead to PST file corruption, such as power failure, hard disk failure, viruses, oversized PST files(too large PST files, file larger than the size limitation, etc.), abnormal closing(you do not close Outlook properly), etc. We have collected a list of the common reasons. For oversized PST files, you can enable the AutoArchive configuration to prevent such an issue.
You can see a complete competitive comparison of our product with other similar MS Outlook PST repair apps in the market. Based on the comparison, our product has the best recovery rate and the most comprehensive functions.
If the problem comes from the corruption of the Outlook PST file, then our Outlook PST repair tool will be able to fix it. Microsoft also provides a built-in Inbox Repair Tool(scanpst.exe), but it only works for very few cases.
If you have backed up your Outlook PST file in the past, you can also try to restore the backup PST file. This method is faster than method 7, since you only need to restore Outlook PST file, not the whole system.
In general, Microsoft support will suggest you use the built-in Outlook PST repair tool, i.e., Inbox Repair Tool(scanpst.exe), to scan and repair corrupt PST files. If that does not work, they will also use our DataNumen Outlook Repair to repair Outlook PST files.
