Skype for Business Online Conferencing Policies: Part Deux

Boris Karloff in Lab

In a previous post, I described how to apply a conferencing policy to an O365 account’s Skype for Business audio/video settings.

I also pointed towards this Technet article, which provides some additional information about these policies.

Reviewing this material however, I noticed that Technet entries (at least, the ones I’ve found so far) don’t go into a lot of detail about what each of these policies includes and excludes.  In other words, how do you know what you’re turning on and off when using the Grant-CsConferencingPolicy cmdlet to modify an account?

The answer, is that you have to do a bit of research within your tenant.

First, you need to learn what conferencing policies can be applied to users within your tenant.

Here’s the syntax:

Get-CsConferencingPolicy -ApplicableTo

The -ApplicableTo switch returns information about what conferencing policies can be activated for the user specified (and it’s a good bet that the same policies can be applied to others within your tenant).

For example:


Identity: Tag:BposSAllModality

AllowIPAudio: True
AllowIPVideo: True
AllowMultiView: True
AllowParticipantControl: True
AllowAnnotations: True
DisablePowerPointAnnotations: False
AllowUserToScheduleMeetingsWithAppSharing: True
AllowNonEnterpriseVoiceUsersToDialOut: False
AllowAnonymousUsersToDialOut: True
AllowAnonymousParticipantsInMeetings: True
AllowFederatedParticipantJoinAsSameEnterprise: False
AllowExternalUsersToSaveContent: True
AllowExternalUserControl: True
AllowExternalUsersToRecordMeeting: False
AllowPolls: True
AllowSharedNotes: True
AllowQandA: True
AllowOfficeContent: True
EnableDialInConferencing: False
EnableAppDesktopSharing: Desktop
AllowConferenceRecording: True
EnableP2PRecording: True
EnableFileTransfer: True
EnableP2PFileTransfer: True
EnableP2PVideo: True
AllowLargeMeetings: False
EnableOnlineMeetingPromptForLyncResources: False
EnableDataCollaboration: True
MaxVideoConferenceResolution: VGA
MaxMeetingSize: 250
AudioBitRateKb: 200
VideoBitRateKb: 50000
AppSharingBitRateKb: 50000
FileTransferBitRateKb: 50000
TotalReceiveVideoBitRateKb: 50000
EnableMultiViewJoin: True
CloudRecordingServiceSupport: Supported

This reveals what Skype conferencing elements are enabled within the BposSAllModality policy (as the name suggests, it’s “all”).

You can also obtain this information by using the simple cmdlet (without referencing a user):


By examining the properties of each conferencing policy, you can learn what makes sense for your environment.

Skype for Business Online: Modifying User A/V Status via PowerShell


Recently I experienced a bit of trouble modifying users’ Skype for Business audio/video properties using the Office 365 web admin GUI.

For example, when trying to save a user’s modified A/V settings (in this case, enabling audio and video), I encountered the following:

Skype for Business Admin Error

Notice the “Sorry, but we couldn’t save your changes…“error message.  This is a bug within the tenant (being addressed by Microsoft as I type this – details about that in a future post).

Needless to say, this is a job for PowerShell.

If you’re familiar with the Skype for Business PowerShell module (and if you’re not, it’s detailed here) you might be inclined to solve this problem by using the following syntax:

Set-CsUser –Identity <User> -AudioVideoDisabled <True|False>

It certainly seems straightforward enough but, TechNet articles notwithstanding, the actual way to accomplish this is by applying a conferencing policy to a user.

Here’s a listing of the conferencing policies I’m familiar with:


And again, you can learn more about what these mean by going here.

So let’s say you want to enable audio and video conferencing (i.e., Skype call) for the user Clever Boots.

You can change his settings by using the following syntax:

Grant-CsConferencingPolicy -PolicyName Tag:YourPolicyNameHere -Identity

You’ve no doubt noticed that you can plug one of the conferencing policies listed above (as appropriate) into the string to enable features for Mr. Boots.
