I have a client with a new windows 7 Pro (64 bit) laptop, running Outlook 2010 on an SBS 2003 network - connecting to Exchange server 2007. This is the only user connecting to the server & she was running Vista with no Outlook issues for 3 years. Since I have installed the new laptop she has had an issue with Outlook "greying out" & it stops responding with the "circle of death" rotating. All other programs remain operational.
After failing to find the cause I rebuilt the laptop, configured it again & it worked fine for about two weeks before the issue appeared again.
There are no entries relating to Outlook in the event log & I am certain that the issue is not with the Exchange server as mail still functions in OWA & gets delivered to her phone.


This is what I have tried,
Scanpst.exe on the .OST file
Disabling addins
Removing Trendmicro
Creating a new profile
Reinstalling Office.

When the issue occurs I try to kill the Outlook.exe process in task manager but receive the following message,

"Unable to terminate process"
"The operation could not be completed"
"Access is denied"

She does have local Admin privileges!
I then have to hard reboot the laptop & then Outlook works fine - for a while.
I beleive that there is some issue with Outlook 2010, running on Windows 7, when connecting to a SBS2003 server, as I have a similar issue on another site with over 20 users. The issue is only affecting one user from 20, again a rebuild only resolved the issue for a week or so.

Is anyone else suffering from this issue & can you provide a solution?
