Skype for Business mobile users can't sign in when Modern Authentication is enabled


Consider the following scenario:

  • Modern Authentication is enabled in your organization.
  • Azure Multi-Factor Authentication (MFA) is also enabled in the organization.
In this scenario, Skype for Business users on iOS and Android mobile devices can't sign in when multi-factor authentication is required and when the Skype for Business organization isn't a pure online organization.


To resolve this issue, use the following options.

For on-premises deployments:

  • Modern Authentication for Skype for Business Server 2015 was released in the March 2016 Cumulative Update (CU2). However, this is only supported for the Windows client without Exchange integration support. There is no workaround to add Exchange integration support.
  • Notice that Lync Server 2013 does not support Modern Authentication.

For Office 365 tenants (pure online):

For Skype for Business hybrid deployments:

  • Modern Authentication for mobile clients is not yet supported in the following deployment topologies:
    • Exchange Online with Modern Authentication turned on and Skype for Business on-premises without Modern Authentication turned on.
    • Skype for Business Server 2015 and Skype for Business Online in a split domain hybrid configuration (for example, SharedSIPAddressSpace = true) with Modern Authentication turned on for both Skype for Business Server and Skype for Business Online.
