1] Repair .pst and .ost files
Start by repairing the .pst and .ost files, as these are getting corrupted, which is the prime reason why Outlook is stuck on verifying data integrity. You can repair the .pst file using the Outlook Inbox Repair tool. Here’s how:
Open File Explorer and navigate to the folder according to your Outlook version.

To repair the corrupted .ost file, remove and re-add the Outlook OST email account. Here’s how:
- Open Outlook, click on File > Account Settings, select the account you want to remove and click Remove.
- Now, add that account and check if it helps.
2] Disable and Re-enable Outlook Add-ins
An add-in can also be why Outlook is stuck on verifying data integrity. To fix this, disable and re-enable all Outlook add-ins. Here’s how:
- Open Outlook and click on Files > Options.
- The Outlook Options window will now open; navigate to the Add-ins tab here.
- Select COM Add-ins beside Manage and click on Go.
- Uncheck the add-in you want to disable and click on OK.
- Close Outlook, restart your device and check if the errors fixed.
If doing so doesn’t work, update all the Outlook add-ins or reinstall them. Alternatively, you can also run Outlook in safe mode and check for the same.
