The server rejected your login
What it means
The mail server received the username and password and refused them, so Outlook stopped checking mail.
Common causes
- A changed password or revoked app password
- Two-factor authentication needs an app password
- IMAP/POP is disabled for the account
How to fix it
- Sign in to webmail and confirm the password works there.
- If two-factor authentication is on, create an app password for Outlook.
- Enable IMAP or POP in the provider's settings.
- Remove the saved password in Windows Credential Manager and enter it again.
