Hello,
We recently moved mailboxes (180 or so) from Exchange 2007 to Exchange 2013. We are noticing that Outlook navigation seems to be very slow compared to the last server. Changing folder views, switching from Inbox to Calendar, Deleting items, etc. Also we used to be able to send 40MB HTML emails very quickly. This now takes about 5 min just to open a reply. (These are tripwire reports.) Most users are using Outlook in Online mode on the new server and were using Online mode on the old server
Environment: Exchange 2013 SP1 on Server 2012r2 Standard (6 cores 24 gigs of RAM, VMWare VM.) Old server is Exchange 2007 8.3.348.2 on Server 2008x64 Standard SP2 (8 cores 12 gigs of RAM.
Physical.)
I have a ticket open with MS but didn't really get anywhere after 9 hours yesterday.
Thanks.
