Classic Outlook account no longer receives emails

Issue

Email profile in Classic Outlook lost connection to the email server. Other methods of accessing email from that account (e.g., New Outlook, OWA) work fine, but removing and re-adding the account in Classic Outlook does not fix this.

Environment

UO-managed Windows desktop

Description

My Outlook profile/account has been disconnected from the server since Thursday 12/12. I am able to access my email/account via the "New Outlook" but would prefer to continue to use the old version. I've done as much troubleshooting as I can and need assistance with getting my account "back online" 

Resolution

Creating a new profile can fix more persistent email connectivity issues:

1. Select the Windows icon, type Control Panel in the search box and select it.
2. In Control Panel, search Mail, and select it.
3. The Mail icon won't appear unless you have Outlook installed and have run the program at least once. The Mail Setup dialog box opens.
4. Click Show Profiles.
5. Click Add.
6. Type a name for the profile, and then click OK.
7. Add an email account to use in your profile by following the directions on your screen.
