FYI. Had messages occurring on 3 servers this morning while checking e-mail accounts via Outlook. “The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect.” Click button to view certificate and it says issued to “eagle.tchmachines.com”, valid from 2/23/2021 to 2/14/2022. Same thing on “baldwin.tchmachines.com”, “lincoln.tchmachines.com” Selected option to go ahead and use the server. No new messages since.
