Hi guys,

Currently we have federation setup between Exchange 2010 sp2 and Exchange 2013.

Free/busy is working perfectly both ways except for contacts sharing.

User A is on Exchange 2010 sp2 with outlook 2010 and user B is on Exchange 2013 also with outlook 2010.

User A shared his contacts with user B and vice versa.

User B on exchange 2013 can view User A's contacts but User A cant see User B's contacts.

User B's contacts is underneath Users A's "shared contacts" but when you click on it, there is nothing in it.

Can someone please help.

Regards
