Mapi session "/o=First Organization/ou=first administrative group/cn=Recipients/cn=Mark.Vega" exceeded the maximum of 250 objects of type "objtMessage".
I get this event in application log every half hour for a while then it goes away for a day or so and then back.
the client is not sending batch email, there is no virus or spyware on his computer. he is not sending large number of attachments. it is always this user, not any other.
the only difference on his computer from others is this program call NEO. which is a program that indexes outlook folders. He has 16 pst folders and one ost folder or mailbox. NEO indexes all of these, and run when ever outlook is open. I assume that the computer is on all of the time, and that outlook is running all of the time, I'll have to check. so it is confusing that this error only occurs intermittently.
how do I figure out what is causing the problem.
