Apply Lync External access policy to everyone on Lync 2010/2013.
Recently I have federated our Lync organization with partner Lync on-pre.
Later management want to apply External access policy to everyone to get Lync federation access.
There are couple of available out of box.
NOTE: By default Global policy get applied to everyone.
1. Using ‘Microsoft Lync Server 2013 Control Panel’ you can easily modify the access policy.
2. Either you can modify ‘Global’ policy and enable ‘Federated user Access’ or modify any other policy and apply the policy to user or group of user.
3. You will see eight by default policy under External Access policy.
Best way to apply external access policy to everyone is Lync management shell.
User following command and change policy name per requirement.
Get-CsUser | Grant-CsExternalAccessPolicy -PolicyName "Allow Federation+ Public+Outside access"
If you want to apply different policy then just replace the policy name.
