Hi there,
I'm Cherrelyn, and I’m here to help.
If your Outlook mobile app suddenly stops accepting your password while it still works on other devices, it could be due to a sync or app cache issue.
Please try these suggestion:
- Clear the Outlook app cache from your Android device settings.
- Remove and re-add the account in the Outlook app.
- If that doesn’t work, uninstall and reinstall the Outlook app entirely.
- Also, ensure your Android system and Outlook app are fully updated.
Sometimes mobile apps get temporarily out of sync, and a fresh setup usually resolves the issue.
I hope this will help and if you have any question please don't hesitate to reply to this thread.
Warm regards,
Cherrelyn
