“It’s very important to note that users may see multiple prompts in some cases, notably where the MA state is not the same across all the server resources that clients may need and request, as is the case with all versions of the Mixed topologies. Multiple Prompts for Users: the TechNet article referenced above calls out an important point that will happen if MA is not enabled equally across all the server resource the SfB clients are using (e.g. Azure AD needs to be the identity provider for SFBO, and on-premises AD needs to be the identity provider for Exchange on-premises.

Pay Attention to Supported Topologies for Hybrid – Especially the Supported Exchange TopologiesĪs we all know, Skype for Business (SfB) is highly integrated (and therefore dependent) on Exchange, which increases the matrix of topology scenarios. This article highlights 5 specific things you’ll want to have answers to before enabling MA in an enterprise.ġ.

In practice, with potentially a decade of legacy client versions, and a now matrix of possible SfB and Exchange hybrid topologies, supporting MA for all the users in an enterprise requires some planning. Microsoft’s name for multi-factor support is Modern Authentication (MA) and support has been added for Skype for Business Server (SfB), Exchange Server, and more recently, the equivalent online cloud services (Exchange Online and Skype for Business Online).
