Exchange 2010
All,
I have an Exchange 2010 server and am in the process of moving users from the Exchange 2003 server and have started to see problems during the move of users. I see outlook is connected but stuck on "updating this folder" and until I restart the server outlook will not update. I can however see all my mail in outlook web access. I have checked the exchange logs on 2010 and this one pops out
"Mapi session "number" exceeded the maximum of 32 objects of type "session"
I'm not sure if this matters but the mailbox database is on a ISCSI SAN
Cheers

Hello,
There are multiple reasons for this (especially Outlook 2003 and Exchange 2010):
http://technet.microsoft.com/en-us/library/ff360476(v=exchg.140).aspx - change session limits
http://technet.microsoft.com/en-us/library/dd159906(v=exchg.80).aspx - disable session limits (possible perf issue of many users cause this).

Had a case where in account options "Download shared folders" needed to be unchecked"
It is a good idea to check also client side usage (shared mailboxes for instance, VPN reinstall might help sometimes).

Spot on!
I'm glad you had great results from this. I just went through it for 300 users so I know the frustrations you were going through. Best of luck with Exchange 2010!
Run EXBPA to identify possible problems, best would be to close outlook before mailbox migration. I had similiar problem when Exchange was out of MAPI connections, a simple registry tweak took care of it.
