our lync deployment uses the users email adress as the sip adress and lync login.
in lync client, you can easily find and add federated users and users on public IM.
internal users are found from the AD adressbook, but they are not beeing detected as lync contacts.
if we search for the sip adress (sip:email@example.com), we succesfully find the lync enabled contact.
does anybody have a clue where this behaviour could come from?
event logs dont show any adressbook synchronisation problems, nor any other error related events. seems the lync
is running fine, so does the edge, except of this issue with finding internal users...
