Install Lync app

Install the Lync 2013 app on your mobile phone with a couple of steps.

  1. From your phone, go to the App Store, and search for Microsoft Lync 2013 for iPhone.

  2. Tap the Free button in the app, and then tap Install and enter your App Store Apple ID and password. As soon as the app is installed, it appears on your home screen.

Remove Lync app

To remove the Lync app from your phone, do this:

  1. Touch and hold your finger on the Lync app icon.

  2. Release your finger when the icon starts to wiggle on the screen.

  3. Tap the X icon that appears in the upper-left corner of the Lync icon. A prompt appears on your screen, informing you that deleting “Lync” will also delete all its data. Tap Delete.

  4. When the app disappears, press the Home button.

Sign in to Lync for the first time

Important: If you haven’t used Lync on your desktop computer and this is the first time you’re using Lync, you need to have a Lync account created and a sign-in address. If you don’t know this information, contact your technical support team. You cannot create a new Lync account from the Lync app on the iPhone.

The first time you sign in to Lync on your iPhone, here’s what you’ll need to do:

  1. Start Lync by tapping the Lync app icon.

  2. Now you’ll see a note explaining that in order to sign in, you need a Lync account and your IT administrator must turn on Lync for Mobile. To confirm that these are in place, tap OK.

  5. On the Never Miss a Meeting screen, tap the field for your phone number and enter your phone number with country/region codes (this should prepopulate with your call forwarding or simultaneous ring settings that you have set on Lync for the desktop). When Lync cannot use the Wi-Fi or cellular data network to make an audio or video call, Lync will call you back at this number to connect you to the audio portion of the Lync call. When you’ve finished entering your number, tap the Next arrow icon.

  6. The next screen displays two default settings on your phone:

  • Push notifications Alerts you when you get a new IM or a VoIP call (on by default).

  • Click the Next arrow icon to start using Lync.
