Set-CsConferencingPolicy

 

Topic Last Modified: 2014-02-24

Modifies an existing conferencing policy. Conferencing policies determine the features and capabilities that can be used in a conference; this includes everything from whether or not the conference can include IP audio and video to the maximum number of people who can attend a meeting. This cmdlet was introduced in Lync Server 2010.

Set-CsConferencingPolicy [-Identity <XdsIdentity>] <COMMON PARAMETERS>
Set-CsConferencingPolicy [-Instance <PSObject>] <COMMON PARAMETERS>
COMMON PARAMETERS: [-AllowAnnotations <$true | $false>] [-AllowAnonymousParticipantsInMeetings <$true | $false>] [-AllowAnonymousUsersToDialOut <$true | $false>] [-AllowCloudPoll <$true | $false>] [-AllowConferenceRecording <$true | $false>] [-AllowExternalUserControl <$true | $false>] [-AllowExternalUsersToRecordMeeting <$true | $false>] [-AllowExternalUsersToSaveContent <$true | $false>] [-AllowIPAudio <$true | $false>] [-AllowIPVideo <$true | $false>] [-AllowLargeMeetings <$true | $false>] [-AllowMultiView <$true | $false>] [-AllowNonEnterpriseVoiceUsersToDialOut <$true | $false>] [-AllowParticipantControl <$true | $false>] [-AllowPolls <$true | $false>] [-AllowQandA <$true | $false>] [-AllowSharedNotes <$true | $false>] [-AllowUserToScheduleMeetingsWithAppSharing <$true | $false>] [-AppSharingBitRateKb <Int64>] [-AudioBitRateKb <UInt32>] [-Confirm [<SwitchParameter>]] [-Description <String>] [-DisablePowerPointAnnotations <$true | $false>] [-EnableAppDesktopSharing <None | SingleApplication | Desktop>] [-EnableDataCollaboration <$true | $false>] [-EnableDialInConferencing <$true | $false>] [-EnableFileTransfer <$true | $false>] [-EnableMultiViewJoin <$true | $false>] [-EnableOnlineMeetingPromptForLyncResources <$true | $false>] [-EnableP2PFileTransfer <$true | $false>] [-EnableP2PRecording <$true | $false>] [-EnableP2PVideo <$true | $false>] [-FileTransferBitRateKb <Int64>] [-Force <SwitchParameter>] [-MaxMeetingSize <UInt32>] [-MaxVideoConferenceResolution <CIF | VGA>] [-Tenant <Guid>] [-TotalReceiveVideoBitRateKb <Int64>] [-VideoBitRateKb <Int64>] [-WhatIf [<SwitchParameter>]]

The command shown in Example 1 modifies a property value of the conferencing policy SalesConferencingPolicy; in particular, the command sets the value of the AllowConferenceRecording property to False. To do this, the Set-CsConferencingPolicy cmdlet is called along with the Identity parameter and the AllowConferenceRecording parameter.

Set-CsConferencingPolicy -Identity SalesConferencingPolicy -AllowConferenceRecording $False

In Example 2, the same two property values -- AllowAnonymousParticipantsInMeetings and EnableDialInConferencing -- are modified for all the conferencing policies configured for use in the organization. To do this, the command first uses the Get-CsConferencingPolicy cmdlet to return a collection of all the available conferencing policies. That collection is then piped to the Set-CsConferencingPolicy cmdlet, which sets the value of both the AllowAnonymousParticipantsInMeetings and EnableDialInConferencing properties to False for each policy in the collection.

Get-CsConferencingPolicy | Set-CsConferencingPolicy -AllowAnonymousParticipantsInMeetings $False -EnableDialInConferencing $False

The command shown in Example 3 modifies the MaxVideoConferenceResolution property for all the conferencing policies that have been configured at the site scope. To accomplish this task the command first calls the Get-CsConferencingPolicy cmdlet and the Filter parameter; the filter value "site:*" restricts the returned data to policies configured at the site scope. This filtered collection is then piped to the Set-CsConferencingPolicy cmdlet, which sets the MaxVideoConferenceResolution property for each policy in the collection to "CIF".

Get-CsConferencingPolicy -Filter "site:*" | Set-CsConferencingPolicy  -MaxVideoConferenceResolution CIF

Example 4 retrieves all the policies where the maximum meeting size is greater than (-gt) 100 and then changes the value of the associated property (MaxMeetingSize) to 100. To do this the command first calls the Get-CsConferencingPolicy cmdlet to return a collection of all the conferencing policies configured for use in the organization. That collection is then piped to the Where-Object cmdlet, which picks out only those policies that have a MaxMeetingSize greater than 100. The filtered collection is then piped to the Set-CsConferencingPolicy cmdlet, which takes each policy in the collection and sets the MaxMeetingSize property to 100.

Get-CsConferencingPolicy | Where-Object {$_.MaxMeetingSize -gt 100} | Set-CsConferencingPolicy -MaxMeetingSize 100 

Conferencing is an important part of Lync Server: conferencing enables groups of users to come together online to view slides and video, share applications, exchange files, and otherwise communicate and collaborate.

It’s important for administrators to maintain control over conferences and conference settings. In some cases, there might be security concerns: by default, anyone, including unauthenticated users, can participate in meetings and save any of the slides or handouts distributed during those meetings. In other cases, there might be bandwidth concerns: having a multitude of simultaneous meetings, each involving hundreds of participants and each featuring video feeds and file sharing, has the potential to cause problems with your network. In addition, there might be occasional legal concerns. For example, by default meeting participants are allowed to make annotations on shared content; however, these annotations are not saved when the meeting is archived. If your organization is required to keep a record of all electronic communication, you might want to disable annotations.

Of course, needing to manage conferencing settings is one thing; actually managing these settings is another. In Lync Server conferences are managed by using conferencing policies. (In previous versions of the software, these were known as meeting policies.) As noted, conferencing policies determine the features and capabilities that can be used in a conference, including everything from whether or not the conference can include IP audio and video to the maximum number of people who can attend a meeting. Conferencing policies can be configured at the global scope; at the site scope; or at the per-user scope. This provides administrators with enormous flexibility when it comes to deciding which capabilities will be made available to which users.

Policy property values can be configured at the time a policy is created. In addition to that, you can, at any time, use the Set-CsConferencingPolicy cmdlet to modify the property values of an existing policy.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Set-CsConferencingPolicy cmdlet locally: RTCUniversalServerAdmins. To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "Set-CsConferencingPolicy"}

 

Parameter Required Type Description

AllowAnnotations

Optional

System.Boolean

Indicates whether or not participants are allowed to make on-screen annotations on any content shared during the meeting; in addition, this setting determines whether or not whiteboarding is allowed in the conference. The default value is True.

Note that annotations are not archived along with other meeting content.

This setting applies to the user who organizes the conference: if set to False, no conference created by a user affected by this policy will include annotations. However, the user can participate in other conferences where annotations are allowed.

AllowAnonymousParticipantsInMeetings

Optional

System.Boolean

Indicates whether anonymous users are allowed to participate in the meeting. If set to False then only authenticated users (that is, users logged on to your Active Directory Domain Services or the Active Directory of a federated partner) are allowed to attend the meeting. The default value is True.

This setting applies to the user who organizes the conference: if set to False, no conference created by a user affected by this policy will allow anonymous participants. However, the user can take part in other conferences where anonymous participants are allowed.

AllowAnonymousUsersToDialOut

Optional

System.Boolean

Indicates whether or not anonymous users (for example, unauthenticated users) are allowed to join a conference using dial-out phoning. With dial-out phoning the conferencing server will telephone the user; when the user answers the phone, he or she will be joined to the conference.

Note that dial-in conferencing is allowed even when this setting is False.

This setting applies to the user who organizes the conference: if set to False, no conference created by a user affected by this policy will allow anonymous participants to join the conference by dialing out; however, the user can take part in other conferences where anonymous users can join by dialing out.

The default value is False ($False).

The default value is False ($False).

AllowMultiView

Optional

System.Boolean

When set to True (the default value) enables users to schedule conferences that allow multiview; that is, clients can receive multiple video streams during a given conference. This setting applies to the user who organizes the conference: if set to False, no conference created by a user affected by this policy can include multiview. However, the user can participate in other conferences where multiview is allowed.

AllowNonEnterpriseVoiceUsersToDialOut

Optional

System.Boolean

Indicates whether or users who have not been enabled for Enterprise Voice are allowed to join a conference using dial-out phoning. With dial-out phoning the conferencing server will telephone the user; when the user answers the phone, he or she will be joined to the conference.

Note that dial-in conferencing is allowed even when this setting is False.

This setting applies to the user who organizes the conference: if set to False, no conference created by a user affected by this policy will allow users who have not been enabled for Enterprise Voice to join the conference via dial-out phoning.

Description

Optional

System.String

Enables administrators to provide additional text about the conferencing policy. For example, the Description might indicate the users the policy should be assigned to.

DisablePowerPointAnnotations

Optional

System.Boolean

When set to True ($True) users will not be able to add annotations to PowerPoint slides used in a conference. However (depending on the value of the AllowAnnotations property), users will still have access to other whiteboarding features. The default value is False, meaning that PowerPoint annotations are allowed.

EnableAppDesktopSharing

Optional

Microsoft.Rtc.Management.WritableConfig.Policy.Meeting.EnableAppDesktopSharing

Indicates whether participants are allowed to share applications (or their desktop) during the course of a meeting. Allowed values include:

Desktop. Users are allowed to share their entire desktop.

SingleApplication. Users are allowed to share a single application.

None. Users are not allowed to share applications or their desktop.

This setting is enforced at the per-user level. That means that some users in a conference might be allowed to share their desktop or applications while other users in the same conference might not be allowed to do so.

The default value is Desktop.

EnableDataCollaboration

Optional

System.Boolean

Indicates whether users can organize meetings that include data collaboration activities such as whiteboarding and annotations.

This setting applies to the user who organizes the conference: if set to False, no conference created by a user affected by this policy will allow data collaboration. However, the user can take part in other conferences where data collaboration is allowed.

EnableDialInConferencing

Optional

System.Boolean

Indicates whether users are able to join the meeting by dialing in with a public switched telephone network (PSTN) telephone. The default value is True.

EnableFileTransfer

Optional

System.Boolean

Indicates whether file transfers to all the meeting participants are allowed during the meeting. The default value is True.

This setting applies to the user who organizes the conference: if set to False, no conference created by a user affected by this policy will allow file transfers. However, the user can take part in other conferences where file transfers are allowed.

EnableMultiViewJoin

Optional

System.Boolean

When set to True (the default value) clients will attempt to join a conference using multiview (which allows the client to receive multiple video streams during the conference). This parameter will be ignored if multiview is not allowed in the conference being joined. This setting is enforced at the per-user level, and for both conferences and peer-to-peer communication sessions. That means that some users in a session might be allowed to have multiple video streams while other users in the same conference might not.

EnableOnlineMeetingPromptForLyncResources

When set to True, users will be prompted any time they schedule a meeting in Outlook that includes invitees (such as a meeting room) that would benefit from having the meeting held online. The default value is False.

EnableP2PFileTransfer

Optional

System.Boolean

Indicates whether peer-to-peer file transfers (that is, file transfers that do not involve all participants) are allowed during the meeting. The default value is True ($True).

This setting is enforced at the per-user level. That means that one user in a peer-to-peer communication session might be allowed to transfer files while the other user is not.

EnableP2PRecording

Optional

System.Boolean

If True, users will be able to record peer-to-peer conferencing sessions. The default value is False.

This setting is enforced at the per-user level. That means that one user in a peer-to-peer communication session might be allowed to record the session while the other user is not.

Optional

System.Int64

Bit rate (in kilobits) used for file transfers. The default value is 50000.

Force

Optional

System.Management.Automation.SwitchParameter

Suppresses the display of any non-fatal error message that might occur when running the command.

Identity

Optional

Microsoft.Rtc.Management.Xds.XdsIdentity

Unique identifier for the conferencing policy to be modified. Conferencing policies can be configured at the global, site, or per-user scopes. To modify the global policy, use this syntax: -Identity global. To modify a site policy, use syntax similar to this: -Identity site:Redmond. To modify a per-user policy, use syntax similar to this: -Identity SalesConferencingPolicy.

Note that wildcards are not allowed when specifying an Identity. If you do not specify an Identity the Set-CsConferencingPolicy cmdlet will automatically modify the global conferencing policy.

Instance

Optional

Meeting Policy

Allows you to pass a reference to an object to the cmdlet rather than set individual parameter values.

MaxMeetingSize

Optional

System.UInt32

Indicates the maximum number of people who are allowed to attend a meeting. After the maximum number of participants has been reached anyone else who tries to join the meeting will be turned away with the notice that the meeting is full. The number of participants specified in this value can be any 32-bit whole number (any value between 1 and 4,294,967,295), but the recommended size is between 2 and 250, inclusive; the default value is 250.

noteNote:
250 is the maximum for shared pool deployments, based on Microsoft testing. For information about supporting meeting with more than 250 participants, see "Microsoft Lync Server 2010 Support for Large Meetings" at http://go.microsoft.com/fwlink/p/?linkId=242073.

This setting applies to the user who organizes the conference: no conference created by a user affected by this policy will allow more than the specified number of participants. However, the user can take part in other conferences where additional participants are allowed.

MaxVideoConferenceResolution

Optional

Microsoft.Rtc.Management.WritableConfig.Policy.Meeting.MaxVideoConferenceResolution

Indicates the maximum resolution for meeting video. Allowed values are:

CIF. Common Intermediate Format (CIF) has a resolution of 352 pixels by 288 pixels.

VGA. VGA has a resolution of 640 pixels by 480 pixels.

The default value is VGA.

Tenant

Optional

System.Guid

Globally unique identifier (GUID) of the Office 365 tenant account that owns the conferencing policy being modified. For example:

–Tenant "38aad667-af54-4397-aaa7-e94c79ec2308"

You can return the tenant ID for each of your tenants by running this command:

Get-CsTenant | Select-Object DisplayName, TenantID

If you are using a remote session of Windows PowerShell and are connected only to Lync Online you do not have to include the Tenant parameter. Instead, the tenant ID will automatically be filled in for you based on your connection information. The Tenant parameter is primarily for use in a hybrid deployment.

TotalReceiveVideoBitRateKb

Optional

System.Int64

Indicates the maximum allowed bitrate (in kilobytes per second) for all the video used in a conference; that is, the combined total for all the video streams. The default value is 50000 kilobits per second.

VideoBitRateKb

Optional

System.Int64

Bit rate (in kilobits) used for video transmissions. The default value is 50000.

This setting is enforced at the per-user level, and for both conferences and peer-to-peer communication sessions.

WhatIf

Optional

System.Management.Automation.SwitchParameter

Describes what would happen if you executed the command without actually executing the command.

Microsoft.Rtc.Management.WritableConfig.Policy.Meeting.MeetingPolicy object. The Set-CsConferencingPolicy cmdlet accepts pipelined instances of the meeting policy object.

The Set-CsConferencingPolicy cmdlet does not return a value or object. Instead, the cmdlet configures instances of the Microsoft.Rtc.Management.WritableConfig.Policy.Meeting.MeetingPolicy object.
