I just ran into something pretty funny, and I am at a loss at finding any logic behind the observed behaviour.
@14.41 I updated the LetsEncrypt certificate on my SOGo server. I did not restart the server or the sogod.
@16.54 or something I noticed outlook stating disconnected (even tho it was actually connected!!). I issued a ‘service sogod restart’ on the mailserver. This fixed the disconnected notification.
@17.01 I had users calling about all the Windows Outlook clients (2013 and 2016) are resyncing their entire mailbox.
Mobile clients seem not affected, just Outlook installations on windows workstations.
Is there a logical reason that this is happening ?
