After installing Lync on my 64-bit PC using 64-bit intall it would not connect.
Cannot sign in because the server is temporarily unavailable. If the problem continues contact your support team

specifically:
Configure the Lync settings
==============================
- In the upper-right area of Lync 2010, click the Gear icon to open the Options page.
- In the Lync – Options dialog box, click Personal.
- Next to the sign-in address, click Advanced.
- Make sure that Manual Configuration is selected and that the configuration values are exactly as follows:
Internal server name or IP address: sipdir.online.lync.com:443
External server name or IP address: sipdir.online.lync.com:443
I did not need to change the firewall. So any changes I had tried, I reversed and removed.
