This issue may occur if the following conditions are true:
You have installed Microsoft Exchange Server 2003 Service Pack 1 (SP1) on the Exchange Server computer.
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.
You are using Microsoft Office Outlook 2007, and you add a large additional mailbox to your profile. For example, this issue may occur if the additional mailbox contains more than one thousand folders.

Try TCP Viewer tool

I normally use this tool first before increasing the Mapi session. This can help you to trace down where is the issue.

Second option is to restart the Exchange services, this can also clear the locked sessions

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Forget to mention in above post. With TCP View tool, you can also kill the sessions. Right click and select End process. This way you can reduce the hung session for an user.

Hope this will help
