Exchange 2003
Outlook 2003
Win XP Pro

Of 60 users on this Exchange server, about 10 access it across a VPN. Of
those 10, one user regularly (once or twice per week) cannot get his e-mail
until I reset the MS Exchange IS service on the server. Nobody else has ever
had this problem, including other users of his station (using their own
AD/Exchange logons). This event is logged on the Exchange server every time
it happens.

Mapi session "/o=<Organization>/ou=first administrative
group/cn=Recipients/cn=<UserID>" exceeded the maximum of 32 objects of type
"session".

He can access OWA while he is unable to access e-mail via Oulook. He works
evenings when there are probably fewer than five users accesing the Exchange
server at any one time, so it is not a load issue. This has been going on for
several months.

I first deleted his entire profile (not just his Outlook profile - his user
profile) from his computer & recreated it from scratch. No help. I finally
discovered that if I reset the MS Exchange IS service, then he can get in.

This user is a very low-e-mail-use user who opens only his own mailbox, so
this is not a matter of opening multiple calendars, etc.
