I keep getting safe mode notification for MS 365

Question

I have msoffice 365 and it kept showing safemode. Then I cannot open any 365 products.

Answer 1

What is the exact error message shown, when you start Word, for example?

An Office repair may be worth trying. See https://support.microsoft.com/en-us/office/lifecycle/repair-an-office-application .

Answer 2

Try Office Safe Mode first to determine whether an add-in is blocking startup.

1. Start an app in Safe Mode:
   • Press Windows key + R.
   • Type one of these and select OK:
     • winword /safe for Word
     • excel /safe for Excel
     • powerpnt /safe for PowerPoint
     • outlook /safe for Outlook
   • If Safe Mode opens, the title bar should show (Safe Mode).
2. If the app opens in Safe Mode, disable add-ins:
   • In the app, go to File > Options > Add-Ins.
   • In Manage, choose the app’s add-ins or COM Add-ins, then select Go.
   • Clear one add-in, select OK, then restart the app normally.
   • If the app opens, the disabled add-in is likely the cause. Re-enable add-ins one at a time to find the problem add-in.
   • Older add-ins such as Abbyy FineReader, PowerWord, and Dragon Naturally Speaking are specifically called out as possible causes.
3. If Outlook is the app failing:
   • Press Windows key + R.
   • Type Outlook /safe and select OK.
   • If Outlook opens, go to File > Options > Add-ins > Manage: COM Add-ins > Go.
   • Clear the selected add-ins, select OK, exit Outlook, then start Outlook normally.
   • Re-enable add-ins one at a time to identify the one causing the crash.
   • Do not remove add-ins during troubleshooting; disable them only.
4. If the app does not open even in Safe Mode:
   • The problem is likely not an add-in.
   • Try repairing Office. If that still does not work, uninstalling and reinstalling Office may be required.
5. If a Safe Mode prompt keeps appearing:
   • Office may have automatically disabled a problem item after a failed startup.
   • Check File > Options > Add-Ins > Manage: Disabled Items > Go.
   • Review disabled items and re-enable only if needed, because the problem can return on the next start.

Safe Mode itself is temporary. To exit it, close the app and start it normally.
