Cause: Lync can only sign in with Lync Server 2010 accounts.
 | Solution: You must use a Lync Server 2010 account. |
Check with your administrator, if you have a Lync Server 2010 account.
Cause: The e-mail address and password were not typed correctly.
 | Solution: Retype your e-mail address and password. |
Passwords are case-sensitive.
If you do not know your corporate e-mail address and password, see your system administrator.
Cause: The firewall that is built into Mac OS X is blocking Lync.
 | Solution: Confirm that your firewall settings are not blocking incoming connections for Lync. |
A symptom of this problem is that Lync
times out while you are trying to sign in.
-
On the Apple menu, click System Preferences.
-
Under Personal, click Security, and then click the Firewall tab.
If the firewall has blocked incoming Lync
connections, see your system administrator.
Cause: Your corporate network connection is not using the network protocol you expect.
 | Solution: Manually configure your network settings. |
When automatic configuration is selected, Lync
uses the TLS protocol. If TLS is unavailable, then Lync
uses the TCP protocol.
To manually configure your network settings:
-
In the Lync sign in window, click Advanced.
-
Click Manual Configuration.
-
Specify the Internal Server Name and External Server Name.
Check with your administrator about the Internal and External server names.
