I cannot open Outlook. Can your product fix the issue?

Many possibilities may make you fail to open the Outlook app. Therefore, we recommend you diagnose the problem with some troubleshooting methods to determine the reason.

If the problem comes from the corruption of the Outlook PST file, then our product will be able to fix it.

If the problem comes from the installation of your Outlook app, then you can repair Office via the following steps:

  2. Go to “Control Panel”.
  3. In the “Programs” category, selectUninstall a program”.

If your Office installation is “Click-to-Run” type, then in “How would you like to repair your Office Programs”, you can select the Quick repair option to replace the corrupt files in the current Microsoft Office installation, including those for Outlook. If that does not work, then you can select the Online repair option to perform a thorough repair.
  6. If your Office installation is “MSI-based”, then in “Change your installation”, click the Repair button to repair the Office installation.

Where is DataNumen Outlook Repair installed?

By default, DataNumen Outlook Repair will be installed in the following directory in a 64bit Windows system:

C:\Program Files (x86)\DataNumen\DataNumen Outlook Repair\

or in the following directory in a 32bit Windows system:

C:\Program Files\DataNumen\DataNumen Outlook Repair\

Does DataNumen Outlook Repair support Windows 10 or Windows 11?

Yes, the latest version of DataNumen Outlook Repair fully supports 32bit and 64bit versions of Windows 10 and 11.

Will Microsoft support be able to fix my corrupt PST file?

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 your PST file. If that does not work, they will also use our DataNumen Outlook Repair to repair your file.

Do you support Outlook for Mac?

Sorry but currently, Outlook for Mac is not supported yet.

How long does it take to repair Outlook files?

The repair time depends on many factors. Below are some of them:

  1. The file size. If the file is huge, it will take a long time since our program will scan and analyze every byte in your file, which is rather time-consuming. For example, a 50GB PST will usually take about 5 to 6 hours to repair.
  2. The complexity of the file. If there are many emails, folders, and other objects in your file, it will usually take more time to repair it. Also, a recently created file is usually less complex than one created several years ago. So it will generally take less time to fix a relatively new file.
  3. The hardware and software configurations of your computer system. A computer with a faster CPU, more cores, and more memory will usually perform faster. Also, a computer with the latest Windows will be able to utilize the full capability of the hardware, so it will also perform faster.
  4.  Bitness of your Windows system and Outlook. We recommend you to run 64bit DataNumen Outlook Repair with 64bit Windows and Outlook, since DataNumen Outlook Repair can use all available memory if your system has more than 4GB memory, significantly improving the performance.
  5. Close all other apps when repairing. It will consume a lot of time and resources to fix a huge PST file. Therefore, we recommend you to close any other apps when using DataNumen Outlook Repair to repair the file.

Can I pause/resume the repair process?

Sorry but that is not possible. If you start a repair process, the only option is to stop it. Later if you want to re-repair the same Outlook file, you need to start over and initiate the repair process from the beginning.

Are there any free tools for PST recovery?

Yes, Outlook has a free built-in Inbox Repair Tool(scanpst.exe) which can be used to repair PST files with minor corruptions.

For different versions and bitness of Outlook and Windows, the locations for scanpst.exe are also quite different. You can utilize the following table to find the directories of scanpst.exe:

Install Type 32bit Windows 64bit Windows
Outlook 2016/2019(32bit) Normal C:\Program Files\Microsoft Office\Office16 C:\Program Files (x86)\Microsoft Office\Office16
Outlook 2016/2019(64bit) Normal N/A C:\Program Files\Microsoft Office\Office16
Outlook 2016/2019(32bit) Click to Run C:\Program Files\Microsoft Office\root\Office16 C:\Program Files (x86)\Microsoft Office\root\Office16
Outlook 2016/2019(64bit) Click to Run N/A C:\Program Files\Microsoft Office\root\Office16
Outlook 2013(32bit) Normal C:\Program Files\Microsoft Office\Office15 C:\Program Files (x86)\Microsoft Office\Office15
Outlook 2013(64bit) Normal N/A C:\Program Files\Microsoft Office\Office15
Outlook 2013(32bit) Click to Run C:\Program Files\Microsoft Office\root\Office15 C:\Program Files (x86)\Microsoft Office\root\Office15
Outlook 2013(64bit) Click to Run N/A C:\Program Files\Microsoft Office\root\Office15
Outlook 2010(32bit) Normal C:\Program Files\Microsoft Office\Office14 C:\Program Files (x86)\Microsoft Office\Office14
Outlook 2010(64bit) Normal N/A C:\Program Files\Microsoft Office\Office14
Outlook 2010(32bit) Click to Run C:\Program Files\Microsoft Office\root\Office14 C:\Program Files (x86)\Microsoft Office\root\Office14
Outlook 2010(64bit) Click to Run N/A C:\Program Files\Microsoft Office\root\Office14
Outlook 2007(32bit) Normal C:\Program Files\Microsoft Office\Office12 C:\Program Files (x86)\Microsoft Office\Office12

This looks a bit complex. So a better way is just to search for “scanpst.exe” on your local computer. As long as you have installed Outlook, you will be able to find it.

However, scanpst.exe only works for very few cases. More specifically, only PST files with minor corruptions can be fixed by it. For badly damaged PST files, it will crash, stop working, or just report an error that it fails to repair the file. In such cases, you need to use DataNumen Outlook Repair instead.
