This is a tricky one to explain.
Old system setup.
Stand alone Exchange 2010 on Server 08 R2 16GB ram dual core
Outlook 2010 on all workstations.
Everything was fine.
Exchange as a VM on server 2012 R2 Hyper-V 32 GB Ram with 3 processors.
Ever since moving Exchange to the Hyper-V server all Outlook clients have random sporadic moments when all of Outlook freezes. I mean everything, minimize, close, all buttons, hotkeys everything. Then after about 5 to 10 seconds to all comes back fine. I cannot believe that this has anything to do with Exchange server... but it started the Monday after moving Exchange to the VM. I have raised the amount of processors and RAM, I have disabled all other VM's on Hyper-V. On the times when it happens to my workstation, I look at the resources of the Hype-V server and the VM and they are not anywhere near maxing out the available resources. I have tried changing outlook from cache mode to non cache mode. I have removed my profile from system completely and re-added it..I have created new users with no email.. I see no errors in the elogs on either the workstation or server.
It seems that no matter what I do this does not go away. Has anyone else experienced this issue?
