Am I understanding your question correctly? It really seems to me like Outlook is prematurely ending IMAP sessions. I also extended the "Server Timeout" setting in OT2010 to 10 minutes, which doesn't seem to help either. (!) I was considering enabling the auth_cache feature to see if that helps. I'll let the list know what happens -- planning on doing that today.

(!)Outlook 2010 is a very old version. Why not update to the 2016 version. I am running it without any problems. If you do update, remember to remove the old version completely first. -- Jerry
