To enable your users to communicate with users who have accounts on a public instant messaging (IM) provider, use the Set-CsTenantFederationConfiguration cmdlet and set the AllowPublicUsers property to True ($True):

Copy Code
Set-CsTenantFederationConfiguration -AllowPublicUsers $True

Note that you must then use the Set-CsTenantPublicProvider cmdlet to specify the public IM providers that your users will be allowed to communicate with.

To disable federation with public providers, set the AllowPublicUsers property back to false ($False):

Copy Code
Set-CsTenantFederationConfiguration -AllowPublicUsers $False
