Ever since I set up Exchange 2010 last year most of the users get "Outlook is trying to retrieve data from the Microsoft Exchange Server servername.domain.com." a couple of times a day. 9 out of 10 times it's when accessing calendars but other times it can just be looking at email.

At first I found it was an issue with our ESET Mail Security, and have since 'fixed' that and the issue has reduced but I am still getting it and it can hang Outlook for 2 or 3 minutes while it retrieves this mystical data. Outlook is setup with cached profiles (Shared and Public folders aren't).

I found out a couple of weeks ago that a FQDN in the "Retrieving Data" message means it's a GC issue rather than an Exchange server issue but I can't see what's actually the problem. We have 10 sites all with their own GC and Exch2010 servers and they all suffer the same.

I'm running out of ideas!

Thanks
 
I have used wireshark in the past and it's not shown anything obvious, but it might be worth me setting up a blank machine to try it on again.

I don't think it's overload on the server, all of our offices have no more than 30 people and some only have 3 or 4 and each one has an Exchange server (I know!) and they all suffer the issue. Exchange is running on Hyper-V with 12Gb of Ram and Quad Xeon, CPU usage rarely goes over 25%

All firewalls are off on clients and servers so don't think it's that.
 
Oh, we've got some ridiculous sized mailboxes size of 15-18Gb aren't unusual. Thing is the older servers running Exchange 2003 didn't suffer the issue, and all our users have cached mailboxes so there shouldn't be large transfers of data.

I've been going through some other things, Exchange Best Practice Analyser has turned up a few things. Also been talking to ESET about it.
 
Well so far the issue seems to have cleared up.

It was caused by ESET Mail Security for Exchange, there was an issue with Background Scanning.

My original thread on their forums - http://www.wilderssecurity.com/showthread.php?t=295683 and a related post - http://www.wilderssecurity.com/showthread.php?t=277715

Have to say I've been a bit disappointed in ESETs products at work (used it at home for years with no issues), the Exchange client has caused several different issues, and the desktop client is killing performance on our older machines. Was reading over the weekend that MS are altering their standard user CALs to include Forefront Endpoint, so might look at trying that when ESET comes up for renewal in a couple of months.
