Check connectors in Microsoft 365
If your email account was compromised, you'll need to check for malicious connectors that can affect your ability to send and receive messages.
- Sign in to the Exchange admin center. Use your Microsoft 365 email address and password (your GoDaddy username and password won't work here).
- Go to mail flow and then select connectors.
- If you don't recognize any connectors listed, select a connector, and then Remove.
