Free/Busy lookups are not working in my enviroment if i try to look up a mailbox in a different AD site.
I can lookup the free/busy information using Office 2007 or 2010 using EWS for any mailbox in the site my mailbox is in.
If i try to lookup theFree/Busy info for a mailbox who is in a different AD site it comes up unavailble. I must be missing some small setting to make this work but i have had no luck looking it up on the internet so far.
Any help is appreciated. Let me know if you need more details on anything.
