What to Do if Microsoft Outlook Only Opens in Safe Mode on Windows

Opening Outlook in safe mode can help you diagnose and fix a variety of issues with the app. However, it can be confusing if Microsoft Outlook is only accessible in safe mode. Fortunately, there’s no need to settle for a subpar experience, as it is possible to fix this issue.

In this guide, we’ve put together a few troubleshooting tips that’ll restore the Outlook app to normalcy.

1. Disable Outlook Add-Ins

Although Outlook add-ins can be useful, they may not always function properly. It’s possible that a conflicting add-in is causing Outlook to open in safe mode repeatedly. To check for this possibility, you can disable all your add-ins and then try to open the Outlook app again.

6. ClickOK to save changes.
   

Restart the Outlook app after this and see if it opens in normal mode. If this solves your problem, it means the add-in which was causing the problem got disabled. To identify it, you can re-enable your add-ins one at a time until the problem occurs again. Once you’ve identified the problematic add-in, you may want to remove it to avoid such issues in the future.
