  • I have a very similar setup.

    Users log in using a SIP name not email address. Yes the SIP name is in the format username @ Domain, but it doesn't have to be an active Exchange Email Address. Your user that now works in Domain B should still be able to log in by putting in credentials for Domain A.

    Alternatively, you can add Domain B as a trusted domain within Lync, and change his SIP address within Lync to be username @ domainB

  • Hi,

    Please explain a little bit more:

    - Trusts between the domains?

    - Are the needed DNS records created in both domains?

    - Is there a different certificate in each domain? It is possible that you need to install the certificate from domain A on user B's pc.

  • Hi , thanks for reply.

    Yes trust between domains , DNS records are ok. Certificate also ok.

    We have many users in both A domain and B domain. All of users use Lync client and it works fine. The problem is in user1 , thar worked in A domain . Now we created The same user1 in B domain.  We can not delete user account from A domain because in B domain it uses special application than require user1@Adomain credentials.

    When i make search of user1 in Lync client I see user1 with user1@Adomain email address. But we deleted email user1@Adomain from Exchange server. 

    The error is  You diddt get sign in. It might be sign in address or logon credentials
