When Outlook is having issues communicating with the sign in server, or having trouble refreshing a login session, a user may see the following behavior:
- A flashing screen may appear
- The user may be continuously prompted for sign-in credentials
- Outlook may not update the inbox at all, despite having closed the application and reopened it
(There may be other behaviors that Outlook exhibits, but these are the most common issues.)
The best way to troubleshoot and oftentimes solve these issues is to completely sign out of the Office account.
