Hi,
I've got very annoying problem with some mailboxes in my organization since I've updated CRM to version 0.1 (2016).
Some details:
1. Dynamics CRM 2016.01 on-premises
2. Mailboxes using server-side sync
3. This mailboxes were working correctly for about a year
4. After some tests and restarts server next mailboxes started to have the same issue: "Unknown Incoming Email Integration Error" (at the beggining only 2 of 4 boxes on this server, after restarts 3 of 4)
5. I asked my mailbox provider about any changes. They told me that in the same time they were updating certificates of the server and I'm using 995/587 ports with SSL
6. In any test of mailboxes it look's like working fine. After 10 minutes in next check - warning again.
Anyone could help a little? I've tried tracing it but don't see nothing special in logs.
