Fix Outlook Account Error

Job ID: 40060340

Budget: $30 – $250 USD

I’m running Outlook on a Windows laptop that’s already connected to my employer-managed Microsoft 365 account and OneDrive. When I try to add my personal newsletter mailbox, Outlook stops with the error message “Cannot connect to the server.”

So far I’ve restarted Outlook, confirmed the internet connection is solid, and applied the latest Outlook updates, but the second mailbox still refuses to add. I need someone who understands multi-profile setups and can remotely diagnose what’s blocking the connection—whether it’s profile corruption, credential storage, registry settings, or a hidden tenant policy—and then get the extra account added and syncing without disturbing the existing work profile and OneDrive links.

Deliverable: Outlook shows both mailboxes, the new account sends/receives properly, and everything syncs as expected.
