Exchange EVENT ID 9646 - 32 Connections to Exchange

On a server that is running Microsoft Exchange Server 2003,
Event ID: 9646
Closing Mapi session "/o=Organization/ou=Administrative Group/cn=Recipients/cn=Recipient" because it exceeded the maximum of 32 objects of type "session".

I found this on the KB - but it did not help.  How can release these sessions and figure out what caused them?

If you look into the Event ID it says the user who is having the Issue.

"/o=Organization/ou=Administrative Group/cn=Recipients/cn=Recipient"

Here the Recipient is the User.

One way to resolve this is to increase the Maximum Sessions on the Exchange Server by editing the Registry.

Else you would need to check with the affected users and see their Client Configuration.

Check why these Clients open more than 32 sessions at the same time.

Could need to check how many windows of outlook they open at the same time. (Like openening different emails seperately).

Check for Outlook Add-Ins.

Check for Additional Mailboxes they might have configured in their Outlook Client.
Also for Additional Calendars or Shared Calendars they might have opened.
All these would help.
