Hello,

Here are some steps you can try:

1. Verify that the login credentials you are using are correct and have the necessary permissions to access the mailbox.
2. Check your network connectivity and ensure that you have a stable internet connection.
3. Ensure that your Outlook settings are configured correctly. You can try removing and re-adding the mailbox to Outlook to see if that resolves the issue.
4. If the issue persists, you can try resetting the Windows credentials cache by going to Control Panel > User Accounts > Credential Manager > Windows Credentials, and then removing any stored credentials related to your Exchange server.
