I am seeing the following event in our Exchange 2007 server since SP3 update. First, I thought the default max sessions were 32 and not 16? Also, other than connection issues what else causes high mapi sessions? Is there any way to reduce the alerts without increasing the session object limits? Dose this cause any problems for the Store or is this just an end user problem? Any assistance would be appreciated. Event Type: Warning Event Source: MSExchangeIS Event Category: General Event ID: 10028 Date: 10/10/2012 Time: 1:02:37 PM User: N/A Computer: Mailbox Description: Mapi session "/o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=user1" exceeded half of the maximum of 16 objects of type "session".
