OAB in Exchange Server 2013 by MSExchangeTeam and a few comments

Hi folks,

Today’s post on MSExchangeTeam was about the new features of OAB in Exchange Server 2013 and that will improve a lot. Just in case I created a summary for you that is coming from 2007/2010 based on their post.

All kudos for the information for Bhalchandra Atre who wrote the original post.

Besides of the information provided by the MSExchangeTeam post I would like to reinforce a few points, as follows:

  • Move-OfflineAddressBook doesn’t exist anymore because as explained in the MSExchangeTeam post the OAB became an arbitration mailbox
  • OAB is ONLY managed by Exchange Management Shell, there is no option to do that using EAC. The only where you can see the OAB in EAC is on the database properties, ABP and mailbox properties.
  • The OAB version is v4
  • If you want to update an specific OAB, the cmdlet will be be Update-OfflineAddressBook –Identity “OABName”

Here is the original post with deeper details about the improvements: http://blogs.technet.com/b/exchange/archive/2012/10/26/oab-in-exchange-server-2013.aspx
