We are runnging Exchange 2003 (SP2) on Windows 2003 (SP2). Recentley we have been seeing Event ID 9646 "Mapi session "/o=COMPANY/ou=First Administrative Group/cn=Recipients/cn=USE
R" exceeded the maximum of 32 objects of type "session".
I have read articles (see below) about decreasing the Mapi Timeout Session..
Value name: KeepAliveTime
Value Type: REG_DWORD-Time in milliseconds
Valid Range: 1-0xFFFFFFFF
Default: 7,200,000 (two hours)
By the looks of the articles this Registry Entry should be there by default but we don't seem to have it. Should we manually add this in?
I don't want to increase the amount of mapi sessions allowed as i want to eventually find the cause of the users that this is happening too.
