What it does

How to perform it

Sign Out

Closes you out of your Lync session and makes it so that others cannot see your status or interact with you. After you sign out, the Lync sign-in window appears, and Lync continues to run in the background, making it easier to sign in again when you’re ready (as compared to exiting, which turns off Lync).

Important:  If you share the computer you’re working on with other users or just want to make it more difficult for an unauthorized users to log in with your credentials, when you sign out, click Delete my sign-in information. Doing so also can make it easier for technical support to troubleshoot any sign-in issues.

In the Lync main window, click the arrow next to the Options button, click File, and then click Sign Out.


Closes the Lync main window, but keeps your session running so you still receive alerts and can quickly interact with others who can see your presence status. Return to the Lync main window at any time by clicking the Lync icon at the bottom of your screen.

In the Lync main window, either:

  • Click the arrow next to the Options button, click File, and then click Close.


  • Click the X in the upper-right corner of the main window.


Closes you out of your Lync session and stops the Lync program on your computer. After exiting, to restart Lync, use the Windows Start menu.

In the Lync main window, click the arrow next to the Options button, click File, and then click Exit.
