We are piloting office 365
we have hybrid exchange on premise and office 365
when users try to connect to lync (every time they initiate their Lync when starting up) the Credential request pops up.
once users enter the username and password it goes away. until next boot up and log in into lync.
this does not affect anyone on the domain except users migrated to 365. the office 365 pilot team seems to be the only one affected. rest of domain users are not. as they are not yet migrated to this model.
any advice would be appreciated.
