We have a problem with our Polycom CX3000 phone to work with our office365 Lync server. We are able to log-in from our laptop by using both Lync 2010 and 2013 clients. After signing-in, if we connect Polycom CX3000 with laptop, lync is prompting to sign-in again to connect the CX3000. When we put our credential, it just says "Sign.in Error , Cannot sign in. Please verify your sign-in address, domain\user name, and passoword and try again" . Please verify that the domain entered @velocis.in is correct."
CX3000 current firmware version is 4.0.7576.0.
Please help. Thank You
