Changing Skype for Business Meeting Lobby Options

The Skype for Business Meeting Lobby:

This post describes how to reset the amount of time an unauthenticated user is allowed to sit on a conference call without the leader present in Skype for Business. Ever connected to a meeting, only to be disconnected from the Skype for Business Meeting Lobby after a few minutes before the leader can arrive in the? This document describes how to change that behavior.

Skype Meeting Configuration Options:

There are a bunch of different configuration options for meetings scattered around Skype. Get-CsConferencingPolicy, will show you the bulk of the configurable options, but in this case, AnonymousUserGracePeriod is configurable from Set-CsUserServicesConfiguration, which also controls some global maximums such as how many meetings a person is allowed to schedule or how many contacts they can have.

AnonymousUserGracePeriod defines the length of time an external (unauthenticated) user can sit in the lobby of a meeting without an authenticated user being present. It defaults to 10 minutes and can be set as high as 1 day, after which the user will be disconnected.

Modifying AnonymousUserGracePeriod:

1. Login to the FE server and open power shell as administrator.
2. Pull down the current configuration of the variable
3. PS C:\Windows\system32> Get-CsUserServicesConfiguration | findstr AnonymousUserGracePeriod
4. AnonymousUserGracePeriod : 00:10:00
5. Now set it to something reasonable, like 30 minutes instead of the default of 10
6. PS C:\Windows\system32> Set-CsUserServicesConfiguration -AnonymousUserGracePeriod 00:30:00
7. PS C:\Windows\system32> Get-CsUserServicesConfiguration | findstr AnonymousUserGracePeriod

AnonymousUserGracePeriod       : 00:30:00
