I had one IMAP user on our 2007 system that was having a similar issue but it was because of his client. I simply increased the number of allowed connections by a few and the issue was resolved. In this particular case there was nothing wrong with the client, but its normal activity is a bit abnormal (Mail.app on mac....)

Remember that other connections can be to exclusive mailbox shares a person may have to another employee/coworker. I don't want to sound condescending but I would like to point out that making sure you have your customers Office Suite patched to current recommendations and that your exchange server has any recent hot fixes and a reboot of both the problematic user you mentioned.
Do you have a replication route to any other exchange servers on campus? Are you running a standalone scenario or a front end setup?
Curiously,

I'm troubleshooting an issue for a user who keeps losing the ability to
connect to our exchange server. The server keeps throwing Event 9646:
Mapi session "/O=MSU/OU=RCPD/cn=Recipients/cn=user" exceeded the maximum
of 32 objects of type "session".
I suspect what we're dealing with is a flaky connection to the network.
She keeps disconnecting, reconnecting and after 32 attempts, the server
just gets fed up and says "enough!" So far, the only ways I have found
to make the server forgive and forget are either to reboot it, or just
wait a long time, obviously not ideal solutions.
My main question though is that while troubleshooting this, I looked at
logons for all users under System Manager. I found that all of my
users are showing multiple logons, usually ranging between 3 to 5. In
the case of the user mentioned above, 32, and the user in the office
next to her had 12. I wonder if I'm dealing with more of a widespread
network issue than just one person?
How many concurrent logons should a single user have under normal
circumstances?
Thanks,
Al
