When a user has too many MAPI connections ( current limit 32 ). Is there a way to close the connections without restarting store.exe ? The close connection on TCPView doesn't seem to do it.

Also, whats the long term fix(s) ?

The error is below. Also, I have BES (Blackberry) going and this person has lots of mailboxes open. Is that likely to cause this?

Update: TCP view no longer shows the connections, but she still can't connect after restarting the computer. Is restarting store.exe required after this happens? –  Kyle Brandt Jul 30 '09 at 14:44
    
But When I go to the particular store in Exchange System Manager I still see lots of sessions. –  Kyle Brandt Jul 30 '09 at 14:53
    
She still had her home computer VPN'd in, I think that did it. –  Kyle Brandt Jul 30 '09 at 15:43

I never encoutered this issue but someone reported that granting the user 'view info store status' rights on the mailbox store solved the issue. It may be related also to the max objects opened during mapi session, there's a kb article here covering that point.

Hope this helps.

This is the correct answer. We had this issue in an exchange 2003 environment for the last year or so. Create a security group and give it this specific permission. Drop users in the group as necessary as you see them show up in the log. –  Tatas Aug 1 '09 at 20:18
