Since this is one of the steps to migrate from 2003-2010 Exchange I want to make sure I do this correctly. According to the MS Exchange Server deployment assistant http://technet.microsoft.com/en-us/exdeploy2010/default.aspx#DeploymentQuestions/ee721959/2003
I need to move the OAB generation server to the 2010 server which will result in a Full OAB download for all clients.
So, with about 100 clients how long will this take? Will there be any disruption when clients open Outlook? Is this something that can be done during working hours, asit may not be such a drastic move?
Also, the OAB are the entries in the GAL, correct?
All of our clients are Outloook 2007 and we do not use public folders. If something goes wrong how can I move the OAB back to 2003 if needed?
