I?ve been working though the last week with our transition from exchange 2003 to 2010.
I hope to write up more of my findings soon, but I wanted to share this one as its happening.
I haven?t been able to get the offline addressbook to download for the users that have been moved.
Outlook 2010 uses IIS not public folders to download the OAB.
I found when I ran the powershell command
Update-GlobalAddressList -Identity "default global address list"
it throws a bunch of yellow warnings, mostly for public folders.
this leads me to think I have some public folder replication issues.
I?ll update more as I dig into this.
Could you post the warnings, i have ran into this issue on deployments where the permissions have not been set correctly, are you running Exchange 2010 SP1?
I’ve made some progress and ran into some other issues. I’ll update the post with this additional information.
