How do I sign in to the Skype for Business app for Office 365?

You need a sign-in address and password from an organization that has a business subscription to Office 365 operated by 21Vianet in China. If you’re already using Skype for Business on your desktop, then you have a Skype for Business 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 Skype for Business account for you.

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.

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 Skype for Business support team.

How long do I stay signed in on Skype for Business app for iPad?

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.
