What do you want to do?

Require Wi-Fi for VoIP, Video, Content

For more information about these settings, go to Adjust your data use settings.

Mobile Number

Enter your Windows Phone number with country/region codes. When Lync can’t use a 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.

  1. From any screen, tap More () at the bottom of the screen, then tap settings.

  2. Under Mobile phone number, enter your mobile phone number.

Push Notifications

Push notifications let you know about a new or missed audio or video call, instant message, or alert when you’re signed in to Lync but aren’t active on your mobile device. To turn on push notifications, set the Push notifications setting to On.


To show your photo and view the photo of other contacts on your mobile device, set the Show photos setting to On.

Phonebook Access

To allow Lync to access your mobile phone contacts using search, set the Phonebook setting to On.


The Exchange screen is where you go if you need to modify the settings that tell Lync how to connect to the servers that support meetings and voicemail.

Important:  Normally there is no need to change these settings. Don’t turn off Use Lync Credentials or Auto-Detect Server unless your support team directs you to do so and gives you the correct values to enter.

If you are directed to change your Exchange Server credentials:

  1. Move Use Lync Credentials to Off.

  2. Tap the appropriate fields and enter your user name, email address, and password, then close the screen.

If you are directed to turn off the Auto-Detect Server function:

  1. Move Auto-Detect Server to Off.

  2. Tap the empty field and enter the fully qualified domain name (FQDN) or URL of your Exchange Web Server, exactly as it was given to you by your support team. Then close the screen.

HTTP Proxy

HTTP Proxy information may be required if you’re connected to a Wi-Fi network that requires proxy information. If you don’t configure the proxy information, you’ll be able to sign in and also sent an IM or call users who are connected to the same Wi-Fi network. But for any other activity, you’ll need to specify the proxy information in Settings. The app can’t discover the proxy from your phone Settings, so you’ll need to add the proxy information specifically in the Lync app settings. To add proxy information, do this:

  1. At the bottom, tap the More (…) icon, and then tap settings.

  2. Tap HTTP Proxy, on the HTTP Proxy screen type your Wi-Fi proxy information, and then tap Set Proxy.

If you don’t know the proxy information, contact your technical support team.


Text telephone (TTY) mode is used to send text over a telephone line. A TTY device must be connected to the Windows Phone to interpret the modified audio. Otherwise you might experience poor audio quality. Using TTY mode in a conference call might also cause audio quality issues.

  • By default, TTY is turned off. Tap On to turn it on.

High contrast theme

If you use your phone’s general settings to select the high contrast theme, Lync will also display in high contrast. High contrast increases the contrast between text and background, which can make the screen easier to read and navigate. To turn it on:

  1. In the App list, tap Settings > Ease of access.

  2. Turn High contrast on.

Screen magnifier

When you turn on your phone’s screen magnifier, you can use gestures to enlarge any page you’re viewing, including Lync pages. To turn it on:

  1. In the App list, tap Settings > Ease of access.

  2. Turn Screen magnifier on.

  3. On any page you want to magnify, do either of the following:

  4. To zoom in the maximum amount, double-tap the screen with two fingers.

  5. To change the magnification, use two fingers to double-tap and hold, then pan up or down to increase or decrease magnification.

  • To turn on Diagnostic Logging, set Diagnostic Logging to On.
