We’re sorry you’re having trouble signing in to Lync. Here are answers to some common troubleshooting questions.

How do I sign in to the Lync app?

You need a sign-in address and password from an organization that uses Lync Server, or has a business subscription to Microsoft 365. If you’re already using Lync on your desktop, then you have a Lync account. 

How do I reset my password?

If you forgot your password, or it doesn’t work anymore, contact your workplace technical support—typically the person who set up your Lync account for you. Provide them with these links:

What’s the format of my sign-in address and user name?

Your sign-in address looks like this: user@domain.com.

You may be asked for both a user name and a sign-in address. The user name is what you use to sign in to your organization’s network, either user@domain.com or domain\username.

I can sign in to Lync on my desktop, but not on my iPad

If your organization is using Microsoft 365, see Lync Online Sign-in Guided Walkthrough for Users.

If your organization is using Lync Server, contact your workplace technical support—typically the person who set up your Lync account for you. Provide them with this link: Deploying Mobility for Lync Server 2013.

Do I need to enter proxy settings?

If you’re behind an authenticated proxy, you’ll need to provide proxy authentication information, as follows.

  • From the My Info screen, under My Credentials, tap HTTP Proxy and then enter your proxy settings.

When do I need to manually specify an auto-discovery server?

If you can’t sign in, you may need to manually specify the auto-discovery server. For more information contact your Lync support team.

I’m trying to sign in on Lync Server 2010 but I have the Lync 2013 app installed

If you’ve installed the Lync 2013 app on your mobile device but you’re trying to sign in to Lync Server 2010, uninstall the Lync 2013 app and install the Lync 2010 app. To install the Lync 2010 app, do the following:

  1. From your iPad, go to the App Store, and search for Microsoft Lync 2010 for iPad.

  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.

Once you’re signed in you’ll remain signed in as long as there is connectivity. If connectivity is lost for 30 minutes, you’ll be signed out. If you have connectivity but haven’t used the application for 10 days, you’ll be signed out.
