Exchange 2007 event ID 9646: "/O=domain/OU=site/cn=recipients/cn=user123456" exceeded the maximum of 32 objects......

I've got some event log errors and OPS MGR alerts for the above event ID 9646 having to do with the user exceeding the maximum of 32 objects of type "session".  All well and good except the cn=user123456 does not correspond to any user I can find anywhere...using ADSIedit or any other LDAP search tools. I have recurring errors with different usernames like the above.....user789012 for instance, also invisible.

Any ideas on what these users are and where to fine 'em?

We're running Exchange 2007 and still have a few legacy Exchange 2003 boxes in the mix although none of them is hosting mailboxes.

Have you checked the following article?
I would recemmend doing the steps menitoned in the workaround section to find out which set of users these are that are causing some many MAPI connections to be established.
I do realise that this article talks about objattachments and objmessage and not abouyt sessions but it may help us in this case

Do keep in mind that its not necessary that this is a user, it can also be
some kind of third party fax connector or outlook addin or voicemail software that is trying to estbalish MAPI sessions  to the server

I've checked out the article you mention.  However, I am not able to configure the views for 'sessions' as you've noted so haven't learned much.  The errors are still occurring.  This is the path noted in the error:  Mapi session :/O=company name/OU=Canwest/cn=Recipients/cn=user73058728

I've tried ADFind, ADSIedit,and a myriad of other tools to sleuth this sucker out but it's well hidden.  There's more than one of them with the same numerical format.

Hmmm.....do you have any third party softwares installed that need to establish MAPI connections to the Exchange Server....What about Outlook addins such as Voicemail Addins etc?

Several add-ins.  I'm wondering if Unity Voice Mail might be doing this since you mention VoiceMail.
I've no cluse why these would consume so many sessions but it might explain why they are spurious and can't be found......what do you think?

Also have Blackberry which uses MAPI and could get carried away.

Thanks for pointing me in this direction.

I may be able to correlate this to Unity Voice Mail or Blackberry.......thanks for steering me this way.

Too many email signature changes to deal with?

Are you constantly being asked to update your organization's email signatures? Do they take up too much of your time? Wouldn't you love to be able to manage all signatures from one central location, easily design them and deploy them quickly to users. Well, you can!
