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
