Outlook Clients in Remote Offices re-downloading mailbox from Exchange 2010
Posted on 2011-10-18
Bit of an urgent issue here. We have several remote offices with a few hundred users total, and everyone of them is re-downloading their mailbox, even though they already have a local copy of their OST up to date, on their machine. (We use Exchange cached mode for all users) We are running EXchange 2010 Sp1 - all the latest updates / rollups. We are running a mixed enviroment of Outlook 2003 / 2007 / 2010.
We have a T1 MPLS, and the line is saturated with mail traffic.
The only change made to the exchange server was a rention policy tag was a applied to about 1/3 of the users (not all at remote offices).
