I am using Outlook 2010 to connect to Exchange 2010.
I just started having this problem today where I can't connect to my exchange server.
In doing some testing I found that if I enable cache mode I am able connect. Nothing has changed on the server and everything else works , active sync, owa, and mail flow.
I have tried connecting through outlook on multiple networks and computers but it just won't connect.
All the Exchange services are started and working.
Any help would be great.
