Outlook Freezing, Outlook 2010, Exchange 2010

In the past month I've seen this issue arise where Outlook freezes sporadically when sending, replying, and even printing for some.   I've been seeing some other questions on EE about freezing which has lead me to do things like make sure the Exchange Servers and clients are both up to date with the latest updates, disable add-ins in Outlook.  Initially I was looking at the Exchange server to make sure there was no pressure on the resources.  I also tried office repairs, removing & recreating outlook profiles.

I'm not sure what to look at in Exchange but from reading all the other posts and answers I didn't see any indicators that Exchange itself would be the issue. To throw this in there also, we currently have two domains in this building and each has their separate Exchange environment and users on both domains are seeing the issue.  One of the servers/environments only contains 20 users and the other 500+.  

Our Environment:
Domain 1 - 20 users
Outlook 2010 on Windows 7
Exchange 2010
     1  CAS/HUB server - HP Proliant DL360 G7 (6GB RAM, 136GB local drive space)
     2  Mailbox servers - HP Proliant DL360 G5's (16GB RAM, 136GB local, 500 ISCSI space)

Domain 2 - 500+
Outlook 2010 and some 2007 with mostly Windows 7 and a few XP
Exchange 2010
     2 CAS servers - HyperV VM (16GB RAM, ISCSI storage)
     2 HUB/MBX - HyperV VM (16GB RAM, ISCSI storage)

ASKER

Also,  I ran the Microsoft Exchange Best Practices Analyzer (Connectivity and Health checks) and nothing came up.
Also tested ping response time from multiple clients, each was 1-2MS replies.
Antivirus was remove from a couple clients, also one Exchange Environment (20 users) does not have any AV.  On the other it's expired and not active so It's safe to eliminate AV.

If both platforms are seeing the issue, then I would have to start looking at what is common between both. Network hardware would be the place to start looking.
Network switch for example. If there are problems with speed negotiation or something like that then it could be when the port is under load that things start to struggle.

Ping doesn't really mean a great deal, it is very low level and as a diagnostic tool close to useless.

Simon.
Is it the same antivirus product in both places?
