How and/or when did this issue appear?

Did you try the registry keys in the mentioned MS KB's?

Maybe a call to Microsoft PSS would be in order, you won't be charged anything if this is a "bug".

The first thing i did when i saw this error was to check the Eventid web site but as i posted earlier there is nothing mentioned about number of MAPI session. something else, some of my clients starts to complain that they are not able to send emails to local users and when i checked the exchange application log i noticed that the exchange server is filled with this event log with their username in the user field of the error. this error disconnect the outlook mapi client from exchange.
so if you have a solution for this let me know.

You know, we're having the exact same problem here, too. Exchange 2003, SP1. The Event Log starts showing recurring messages of:

Mapi session "852c273a-01a9-4907-bab8-3f2a2efe00c8" exceeded the maximum of 32 objects of type "Session"

And at some point, users are no longer able to connect to Exchange via Outlook. Restarting the ExchangeIS service seems to fix this problem, but we're not quite sure of the exact nature of the problem in the first place! Argh!

I've also found this KB entry:

http://support.microsoft.com/default.aspx?scid=KB;EN-US;830829

SYMPTOMS
Your Microsoft Exchange Server 2003 computer may stop responding.

CAUSE
This problem may occur if a MAPI client opens more than the default value of the following server objects....

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section (Exchange 2003 Std & Enterprise).

From the Event Log itself, here's another explanation of Event ID 9694:

Explanation
A single MAPI session has exceeded the maximum number of objects of a given type. To prevent a single client from affecting the performance of the entire server, this MAPI session was terminated.

User Action
This can be caused by a very high usage level by an individual user. If these errors are happening regularly, you can raise the default maximum for the affected object type (for example, to twice its default level). If at this level the specified user is continuing to generate this warning, investigate the user actions that are causing this warning. It can be caused by improper client design or unusual client usage patterns.

if you go back to my first post you find that I included two of microsoft KBs (Microsoft KB830829 and KB830836 ) and both are not saying anything about the number of MAPI sessions. still i can not find any explination or solution fro this error, and i do not want to keep restarting the IS as you are doing. anyone have a solution please post here.

For me it start to clear itself with no intervention. i only noticed that my wireless users are the most to have this issue, so i instructed them to use the LAN while in office. i still have this issue with one user from time to time and still i do not know why

We have the same problem here. It happened since we moved a mailbox from our exchange 5.5 server to our exchange 2003 server. This mailbox may be used intensively. The problem is that the Event is refering to other mailboxes, not the one we moved...

Was it the case for you mustafa ?

I too am receiving the same error. I'm on W2k3 Std Srv with E2k3 Sp1. This started when my Compaq SCSI array controller bombed and put the Exchange DB in a "dirty state" and I needed to do a eseutil /p to bring it up. At the same time I needed to

It seems to be happening to various individuals at various times throughout the day/night.

Any ideas is greatly appreciated.

I've seen this problem today, and I'm fairly certain it's due to a couple of users who had delegate access set up wrongly. Not only did the manager have his secretary listed as a delegate, but also the secreatary had the manager listed as her delegate. Responses to meeting requests were going back and forth between the two of them. I've corrected this and implemented the registry settings in KB 830829, so hopefully, it's now sorted out.

I am too having the same problem. the 9646 states that a user has exceed the maximum of 32 sessions. Then the user can no longer connect to exchange via Outlook. I have to stop/start the information store in order to clear the situation. This is happening daily.
I tried increasing the max values, but i am not sure which one is associated with the 32 sessions.

HELP.

We got the same "session" here today (W2K3, E2K3). Went into the Exchange System Manager and drilled down to the Mailbox Store -> Logons folder and the user that was locked out of Outlook had 32 logon sessions active.
Restarting the IS service worked here too, but I'm not sure of the cause.

After a little more digging I discovered this user was keeping Outlook 2k3 open over a VPN connection. Outlook was running in "Cached Exchange mode". Most of the 32 logons recorded in the System Manager were in that mode. I'm having her disable this mode to see if it stops.
