Hi,
Please run the following command to check the IMAP settings in server side:
Get-IMAPSettings | fl
In client side, is there any error descriptions? Additionally, please collect any related event logs from server side for further analysis.
Howdy,
We have a CAS server and a Mailbox server. I ran the command from the CAS server and here's the output I got:

I checked event viewer on both systems and didn't find anything.
