Can sign onto Lync

This question is not answered This question is not answered

I went to

And followed the steps to

-          Upgrade to Office Professional Plus

-          Installed MS online services

-      Installed Lync

-          Setup Office 365 for desktop

-          Online services sign in assistant

-          Set up and configure office desktop apps

-          Finally reboot as requested


Though I could sign into the protal using by credentials, whenever I try to sign into Lync, I get this error:

  Cannot sign in to Lync

  Cannot sign in because the server is temporarily unavailable.


Other people in my organization can sign in and use Lync.

I have been getting this message for over a day.

I tried uninstalling and reinstalling.

Also the Lync sign in window only ever offers my user id as a text field not the password. Is there a way to get it to show the password as a separate field again?

  • Hi BarryB4,

    At first, please try to manually configure Lync:

    1. In the upper-right area of Lync 2010, click the Gear icon to open the Options page.

    2. In the Lync - Options dialog box, click Personal.

    3. Next to the sign-in address, click Advanced.

    4. Make sure that Manual Configuration is selected and that the configuration values are exactly as follows:

         Internal server name or IP address:

         External server name or IP address:

    5. Try to sign in Lync again.

  • The first set of steps did not work. I cannot do the second set as I am not admin. I will request that the admin try them.

  • This did not work.

  • Tried the second part too with assistance from my admin, but it did not work.
