Sending, receiving, and organizing email in Outlook.com
For an Outlook.com/Hotmail sign-in loop, deleting and re-adding the account is the documented fix for the alias-related login issue in Outlook mobile: Settings > select the affected account > Delete Account, then add it again. If the issue continues, use Settings > Help & Feedback > Contact Support.
For the account itself:
- The email address remains the same when the account is re-added. Re-adding the account does not create a new address.
- If the mailbox still works on the web, mail is stored on the server and should resync after the account is added again.
- If Outlook on Windows is the problem, creating a new Outlook profile can help. Steps:
- Close Outlook.
- Open Control Panel > User Accounts > Mail > Show Profiles.
- Select Add, enter a profile name, and select OK.
- Enter the email address and password for the primary account and complete setup.
- In Show Profiles, select Prompt for a profile to be used.
- Start Outlook and choose the new profile.
If creating a new profile fixes the issue, the old profile can be deleted afterward.
If the username is not recognized during sign-in, try another alias or phone number on the account, if one exists.
