A user using Outlook in desktop is continuously experiencing an issue in Outlook where it does not connect. Status bar show "Trying to connect..."
I ran fiddler on their PC and it showed bunch of errors. It returned "HTTP Error 503. The service is unavailable".
This is an Office 365 mailbox. What could be causing this issue?
