Hello Everyone,

I am finishing up an Exchange 2013 migration from 2007.  I am currently still in coexistence and had some questions around the Global Address List and Free Busy Information.

How to I tell if my clients are pulling address book information from my Exchange 2013 or 2007 Global Address List?  I don't want to remove the 2007 system if the clients are pulling from it.  All mailboxes are moved to Exchange 2013.

How do I make sure my clients are pulling the Fee Busy Information from Exchange 2013 or 2007?  If I remove my 2007 servers will my clients lose Free Busy Information?

How do I tell what Exchange version my clients are getting this information from?

Thanks for any assistance!

Ian...

Hello,

Free/busy information are retrieved from users mailbox by EWS service.

GAL(I think you may refer to OAB), we can use the following command to get its generated server:

Get-OfflineAddressBook |FL
