Lync 2010 continuous prompts for Office 2010 users
Posted on 2011-02-17
Lync 2010 is deployed internally. All the Office 2007 users are fine, but users who have Office 2010 installed are getting 4 prompts for credentials after the sign-in to Lync. The prompts say "Credentials are required. Type your user name and password to connect to.. W, X, Y, or Z. W= "the certificate service". X= "for retrieving response groups". Y="the corporate address book". Z=" retieving location information"
Providing the credentials in all formats does not help (Domain\username, UPN,..etc). The users have to cancel out of each prompt. Lync works fine after cancelling, but users cannot search for corporate contacts.
February Lync cumulative update installed for the users, but the prompts are still there. Tracing is not showing anything relevant.
Any ideas, experts?
