Using Outlook for Android for personal email and calendar management
Hello,
I understand that you are having trouble signing in to your Microsoft Account on the Outlook Android app.
- Could you please let me know whether you are using a Personal or Work/School account?
- Can you sign in to Outlook on the web with your account?
Open a Private browsing tab and go to https://outlook.live.com/
If there's nothing wrong with the account itself,
As a first step, uninstall and reinstall the Outlook app from the Play Store.
If you are still having trouble signing in,
- Go to Settings on your mobile.
- Then, go to Accounts & Backup > Manage accounts.
- If your Microsoft account is listed, select it and tap 'Remove'.
- Once removed, add your Microsoft account again on your device and then sign in to the Outlook app.
Let me know if you still need more help.
