Greetings,
Since presenting Exchange 2013 to our environment in a co-existent state, we are noticing users whos mailbox is still on Exchange 2010 they are download an old Offline Address Book. The database that these users mailbox is on is still set to download the 2010 version. I have even changed the database properties to point to the 2013 address book but the Outlook client still is downloading an out of date address book.
I have performed the following commands but the users are still not downloading an updated Address book.
Get-OfflineAddressbook | Update-OfflineAddressbook
Get-ClientAccessServer |Update-FileDistributionService
From their local machine I have delete the "Offline Address Books" folder from
C:\Users\USERID\AppData\Local\Microsoft\Outlook\ and started Outlook again but it still downloads an old version.
My mailbox is on 2013 and my offline address books folder has a file called "udetails.oab" that is around 1,139KB. My users who are on Exchange 2010 have the same file, but the size is around 690KB.
How can I get the OAB from 2013 to properly update the 2010 version?
Cheers
