Since a few weeks, whenever I used Outlook for some time (5-10 minutes), I
start getting the error
Cannot expand the folder. There is not enough free memory to run this
program. Quit one or more programs, and then try again.
When I quit Outlook and open it up again, I can then again work for 5 - 10
minutes before receiving the error again.
The error appears whenever clicking or expanding a folder (public folder or
mailbox folder) except for the Inbox, which is always working, but for
example clicking on "Sent Items" or "Outbox" produces the error, as well as
any Public folder.
When the error occurs, mail in the Outbox also doesn't get sent until I
restart Outlook.
I'm running Outlook 2007 on WinXP with all the latest service packs
installed. Outlook 2007 runs in Exchange Cache mode, in RPC mode (not RPC
over HTTP), and I'm connected to the office by VPN.
I have disabled all add-ins, there is plenty of memory available (no other
programs running and 2GB free memory available out of 4GB), I have tried
fixing the .ost file (3.5GB) with scanost.exe, I even tried creating a new
..ost file, the same error occurs over and over again.
OL 2007 was running fine for a long time (more than a year) with the same
..ost file, same connection, even with Add-ins enabled. The errors started
appearing only some weeks ago. I guess some Office update or service pack
must have created the problem.
What can I do?
Any help is appreciated.
Thanks,
Nour
