Closing Mapi session ... it exceeded the maximum of 32 objects of type "session".

I recieved this error on the Exchange 2003 server from a Outlook 2010 client.

I was making network changes and eventually found that my Outlook Mailbox was permanantly "Disconnected".

I read through this http://support.microsoft.com/kb/842022

and have determined that indeed the cause was (as stated)

"•A program that is running on a client computer opens many MAPI sessions to the Exchange Server computer. The number of MAPI sessions is larger than the permitted limit."

This article defines the problem, but gives no solution.

How do I clear this issue so that my Outlook will no longer be 'disconnected'  Will this time-out eventually, or do I have to restart the server?

The error doesn't say how long the session is that "32" is the maximum.

Any help or ideas greatly appreciated.

Thanks.  I wish the other materials had stated how to clear this.

Outlook came right up after restarting last night.

THanks again!
