I have a brand new Dell i5 Laptop, 6GB of RAM with 64bit Windows, along with 64bit Office and Outlook attached to Exchange 2010 (onsite). I am getting all sorts of memory related Outlook glitches such as: cannot open folders in the users main mail mailbox, cannot view other shared mailboxes, cannot move messages between folders, the Calendar view defaulting to List view instead of the proper view the user had set.. etc. The error I get a lot is in the title: "Cannot expand this folder. There is not enough memory to perform this operation"
I even totally wiped the machine installed a non-OEM copy of Win7 64bit (Enterprise) and it still has the same problem on a clean install. I am also using /safe in Outlook for troubleshooting, and it hasn't helped at all.
A few notes: I am in cached mode and want to stay that way, Outlook should work fine in this configuration with Exchange.
The paging file is set to system managed currently, but before I reinstalled, I did try to manually set it to 9GB min, 12GB max.. no change.
This user has a large mailbox, plus opens 2 more additional large shared mailboxes.. so the OST file is large, around 3.6GB total.
I have also tried disabling the AntiVirus (Symantec EndPoint) temporarily.. and that doesn't seem to help anything either.
The users old laptop works fine with WinXP and Office 2007... in which they find ironic their new laptop and new software can't seem to handle it!...
