Power Users in Outlook 2007 Cannot Open Items

[removedashes]

On a regular basis, Outlook 2007 becomes will not open new mail items
and/or other folders for our power users.

Outlook is configured for RPC over HTTP mode against a number of
Exchange servers (different farms, different locations, one common
problem). Frequently, users get an error akin to:

(this one was produced by Advanced Find)

Outlook cannot perform your search. Outlook cannot display this view.
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.

---

In most cases the users have a number of Outlook windows open - main
mail window, calendar, task lists - power users.

This issue only affects our Outlook 2007 users, the Outlook 2003 users
are not affected.

The current remedy is to restart Outlook.

As we receive more reports from the field, I'll add more excerpts.

Regards,

Another error encountered, randomly -

When filing an item from the inbox,

Cannot expand 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.

In this case, nothing was open except for Outlook's main window.

I have seen the same problem, but have still not found a solution.

i have been looking at increasing the number of RPC connections on the
Exchange server, but since we use an exchange 2007 i have been unable to find
the correct registry key to modify.

I have also tried to disable add-ons from the trust center (such as Adobes
add-ons).

The only thing so far that i can think of is the user has also opens some
other mailboxes than her own (which is by design). Although it is not an
usable solution to close these (this was no problem when running Outlook 2003
and Exchange 2003).

Agreed, in the meantime, we have to abandon office 2007 and revert back
to office 2003 until this is addressed by MSFT.

Just a thought, do you see Event ID 9646 in the Exchange server Application log for that user? I have the same issue with an Outlook 2007 user and it seems like she has an unusually large number of folders open that surpasses the default threshold number for that type of objects on the Exchange server. There is a KB article on how to modify the registry to increase that number (KB830836) but it looks to me that Outlook 2007 does not close the folders properly sometimes and it creates sort of a connection leak when the number of open folders piles up and to me that is the real issue here. Let me know if you have the same symptoms.

Is Google Desktop installed?

Hi

I am seeing this very issue, but only since installed the Google Desktop Outlook plug-in, I was wondering if this may be a common theme?

I've had a scout around the Google Desktop forums and the issue was reported back in April 2007 but with no answer.
