Exchange 2007 event ID 9646: "/O=domain/OU=site/cn=recipients/cn=user123456" exceeded the maximum of 32 objects......
Posted on 2009-03-31
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.
