BES5 SP2 with mailbox hosted in EX2010.

I have added 6 EX2010 and 18 EX2003 users without any problems.

However whenever I try and add a 2003 user now I get a BES error which I've listed at the bottom.

On the EX2003 SP2 server I am getting a 9646 BESAdmin exceeded the maximum of 32 objects of type "session" event.
The BESAdmin account DOES have View Only Admin, SendAs/RcvAs AND Administer Information Store rights on the server and all the Stores. IS has been restarted.

Any thoughts?
Thanks

look at these two links

MSExchange IS Application Event ID: 9646
Event ID 9646 is logged in the application event log of your Exchange Server 2003 computer when a client opens many MAPI sessions

We bumped into the same issue... dialed up up MAXSESSIONS to resolve.

Thanks Knotty. Unfortunately BESAdmin already has the View Information Store Status right set as part of View Only Admin.

Mikey - I presume your bes account also had View Only Admin Set? What did you turn the maximum number of sessions up to?

Thanks
