If you're unable to send or receive emails at your address, here are some steps you can follow to troubleshoot the issue:
- Check Email Settings: Ensure that your email settings are configured correctly. Verify that SMTP is enabled and that the SMTP server settings are accurate.
- Review Email History: Access the Email history page to check for any errors related to sent emails. Look for emails marked as "Failed" and examine the failure details for insights into what went wrong.
- Validate User Mailbox: Confirm that the email account you are using exists in Office 365 and has the necessary permissions. You can do this by signing into the affected user mailbox to ensure it is valid and accessible.
- SMTP Account Credentials: Make sure that the SMTP account you are using is accessible and that the login credentials are correct.
- Check Mailbox Availability: If you encounter errors indicating that the mailbox is unavailable or that the server cannot be reached, check the connectivity to the email server and ensure it is properly configured.
If these troubleshooting steps do not resolve your issue, consider reaching out to your IT administrator or contacting Microsoft support for further assistance.
