Summary: Use the Lync cmdlets to add an additional domain to Lync for federation access.
I'm working with a client to set up a federation, and I am trying to easily add their list of domains.
How can I do this with Windows PowerShell?
In Lync, use the New-CSAllowedDomain cmdlet:
NEW-CSAllowedDomain –identity 'fabrikam.com'
NEW-CSAllowedDomain –identity 'contoso.ca'
