Running Exchange 2007 on the server with an Outlook 2007 SP2 client, I'm getting an odd message when I try to view specific folders in my Outlook mailbox:
"Cannot display the folder. Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachments and images from unsent messages you are composing."
I currently have no unsent messages and no emails opened (I'm just trying to look at the list of emails in the folder)… I found someone suggested setting the following registry setting on the server:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
Value: Disable Session Limit
However I don't see that parameter in the registry, and I'm a little hesitant to just add it without knowing if it applies to Exchange 2007 or an older version.

Have you tried this KB article?

There was a Technet newsgroups moderator that suggested it.
It appears to be only an issue with Outlook 07 itself, not Exchange...as Outlook 03 clients don't seem to have this issue. It appears to be related to large numbers of RPC calls or large numbers of folders in a mailbox (or even an attached additional mailbox you are connected to).
Is Outlook at sp2 (office 07 sp2)?
