Error message ‘Data file is being checked’ resolved

Unexpected power outages are the most common reason which can lead to Outlook data file (.pst file) corruption. When this happens, Outlook may scan your data file for consistency errors the next time it starts. If you manage to get rid of the file errors, then start Outlook as normal, otherwise you may encounter even more access problems. To fix such issues, you need to take some special measures to restore Outlook Inbox.

The above description provides a brief overview of some likely problems in Outlook. Here the problem is more specified by a suitable realistic example. Consider a case where your Outlook has not closed properly. As expected, on the next attempt to start Outlook, it gives an error that the Outlook data file is not specified and so Outlook checks it for errors. Consequently, the system slows down. But contrary to your expectations, the check is not completed. Every time you check the bottom right corner of the screen, you will see something like:

‘Data file is being checked …’


Outlook cannot automatically repair corruption of PST files. This can also be the result of a third party add-in.

User action

To check if this is the case of a third-party add-in, start Outlook in safe mode and try to disable the add-ins one by one. This will help you detect the problematic add-in that is causing the problem.

If disabling add-ons does not solve your problem, try repairing the damaged PST with Outlook’s Inbox Repair Tool, which can be accessed through an associated program file, Scanpst.exe. To run it, locate the file with Windows search option, double click to open it, browse to the location of your PST file and click Restore. This will start the file scanning process and prompt you for a success message in restoring the file. However, if it cannot restore your file, the last alternative is to restore from a previous backup or run an external PST repair tool.

A third-party PST file repair software can scan your damaged PST and fix Outlook Inbox using safe and effective scanning algorithms. Moreover, these applications are easy to use even without prior technical knowledge.
