My outlook is disconnected at the server

Question

I have done all of the troubleshooting, and none of it works. I have an email address that I use daily, but it is still legacy connected to an old email that I am no longer using. It suddenly stopped working on all of my devices at the same time. My Teams account is still fine.

If your Outlook is showing as disconnected from the server, there are several potential causes and resolutions you can consider:

1. Profile Issues: If you have multiple mailboxes in your Outlook profile, ensure that the accounts are set up correctly. A mismatch between your Windows account and the mailbox account can cause disconnection. It may help to recreate your Outlook profile to resolve this issue. You can find instructions on how to do this here.
2. Software Updates: Ensure that your Outlook client and Windows operating system are up to date. Outdated software can lead to connectivity issues. Run Windows Update to check for the latest updates.
3. Network Issues: If IPv6 is enabled on your network adapter, it may cause connectivity problems. You can try disabling IPv6 to see if that resolves the issue. Instructions for disabling IPv6 can be found in the relevant documentation.
4. Service Issues: If multiple users in your organization are experiencing similar issues, check the Microsoft 365 Service health status to see if there are any ongoing service disruptions.

If you've already tried these troubleshooting steps and the issue persists, consider reaching out to Microsoft support for further assistance.
