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.
