Logged into a terminal server so we do not want cached mode. We had been using RPC/HTTPS previously and it seemed to work pretty well. After upgrading to SP1 and enabling the MAPI/HTTP connection and performing the app pool config changed in
the release notes we are still seeing performance issues. One issue that happens often is sent mail will stick in the Outbox. If we restart outlook, edit the message and such and resend it will eventually work but if users are not looking for this
it may never be sent. Another issue is there are times where the client will hang for half a minute or so when trying to open e-mails from popup notifications, sometimes failing and causing us to have to retry after which it succeeds. CAS server
has 12GB RAM and is using less than half of it; not seeing high CPU utilization either. Connections appear to be fine when looking at the Status in Outlook with only 1 or 2 failed requests, and average responses of about 40-50. It reports build
is 15.0.847.30 which doesn't seem to be the most current.
