Sign in to and sign out of Lync

After you install Lync from the Microsoft Office 365 portal and sign in to it for the first time, you’ll be automatically signed in to Lync the next time you log in to that computer.

 Note    For details about Lync startup behavior and how to change it, see Set Personal options.

Sign in to Lync for the first time

  1. Log in to your organization’s network.
  2. Click Start, click All Programs, click Microsoft Lync, and then click Lync 2013.

Your Lync sign-in information is usually configured automatically when Lync is installed. If you can’t sign in, see Troubleshooting Lync Online sign-in errors.

Sign out of Lync

When you want to leave Lync, you can close your display, sign out of your session, or exit from the program. You carry out all three options from the File menu. Here are the differences among the options:

Option How to perform it What it does

On the Lync main window:

  • Click the Options button, then click File>Close


  • Click the X in the upper-right corner of the window.
Closes your Lync display but allows the Lync session identified with your user ID to continue to run, so you’ll be able to receive alerts and quickly interact with others. You can reinstate the display at any time by clicking the Lync icon in the Task Bar or the notification area at bottom of your screen.
Sign out On the Lync main window, click the Options button, then click File>Sign Out.

Ends the Lync session associated with your User ID but allows the Lync application to continue to run in the background. When you sign out, the sign-in window will appear.

 Tip    You can click Delete my sign-in information when you sign out to remove the record of your login ID and password from the computer’s cache memory. Doing so may make it easier for support people to troubleshoot sign-in issues, and it can also help ensure that your sign-in information is secure by making it more difficult for unauthorized users to log in with your credentials.

Exit On the Lync main window, click the Options button, then click File>Exit. Ends your Lync session and shuts down the Lync program on your computer. After exiting, you would go to the Windows Start menu if you wanted to restart Lync.
