  • Hello Sandeep,

    Here some hint how Lync authenticate and why you will get authentication prompt sometimes.

    You still using only on-prem server right?

  • Hi Sandeep Kumar Bhardwaj,

    For your issue, would you please give us a screenshot for credentials prompt of Lync 2010 client?

    Did the issue only appear on the specific Lync client?

    After you input the credentials, can you sign in successfully?

    If the issue only appeared on the specific Lync 2010 client, please try to rebuild Lync profile then test again.


    If all users had this issue, please try to check if there are any event errors in application log.
