These clients are not supported by Skype for Business Server 2019.

Infrastructure requirements for Skype for Business on Mac

The Skype for Business on Mac client leverages both the Unified Communications Management Platform (UCMP) as well as the Unified Communications Web API (UCWA) that our mobility clients use.

The client has the same requirements as our mobility clients in that you must have an Access Edge Server and Reverse Proxy deployed in a supported configuration.

Authentication

The Skype for Business on Mac client supports Cert-based authentication, Microsoft Modern Authentication, and Multi-Factor Authentication when deployed and enabled.

Catalina

Note

Due to a current limitation, the user's Exchange credentials must be the same as their Skype for Business credentials.

Certificates

Certificates in use on the Access Edge, Reverse Proxy and Front End servers must not use the SHA-512 hash algorithm.

The HTTP Certificate Revocation List must be defined and accessible by the client. For example, we don't support an LDAP entry in the certificate as your Certificate Revocation List.

DNS

Mobility must be properly deployed for the Skype for Business on the Mac client to function properly. A common failure scenario is to have both of the following DNS entries resolvable on the internal network:

  • lyncdiscoverinternal.<sipdomain>

  • lyncdiscover.<sipdomain>

For more information, refer to: Deploying Mobility in Lync Server 2013, and the Microsoft Lync Server 2010 Mobility Guide.
