MS-721: Which PowerShell Cmdlet Enables One-Touch Join for Third-Party Meetings in Microsoft Teams Rooms?

Discover how to configure Microsoft Teams Rooms for third-party meeting integration using the critical PowerShell cmdlet Set-CalendarProcessing. Perfect for MS-721 certification prep.

Question

You have a Microsoft Teams Rooms device that is configured to use Direct Guest Join.

You need to use PowerShell to enable the device to support a one-touch experience for joining third-party online meetings.

Which PowerShell cmdlet should you run?

Select only one answer.

A. Set-CalendarProcessing
B. Set-DeviceConfigurationPolicy
C. Set-DeviceTenantPolicy
D. Set-ResourceConfig

Answer

To enable a Microsoft Teams Rooms device to support a one-touch experience for joining third-party online meetings (e.g., Zoom, Webex), the correct PowerShell cmdlet is Set-CalendarProcessing.

A. Set-CalendarProcessing

Explanation

Teams Rooms devices support a one-touch experience for joining third-party online meetings, also referred to as Direct Guest Join. When enabled, you can use Teams Rooms to join meetings hosted on Cisco Webex and Zoom just as easily as you can join meetings hosted in Teams. The first thing you must do to enable a one-touch join experience from Team Rooms is configure the calendar processing rules for the device’s Microsoft Exchange Online room mailbox. The room mailbox must allow external meetings and retain the body and subject of email messages so that it can see the URL needed to join a third-party meeting. You configure these room mailbox options by using the Set-CalendarProcessing cmdlet.

Why Set-CalendarProcessing?

Direct Guest Join Requirements

Third-party meeting integration requires configuring the device’s Exchange Online room mailbox to:

  • Process external meeting invitations.
  • Retain meeting details like URLs in calendar invites.

The Set-CalendarProcessing cmdlet modifies these mailbox properties.

Key Parameters

Run the command:

Set-CalendarProcessing -Identity <RoomMailboxUPN> -ProcessExternalMeetingMessages $True -DeleteComments $False
  • -ProcessExternalMeetingMessages $True: Allows the mailbox to parse third-party meeting details.
  • -DeleteComments $False: Preserves invite body text containing meeting URLs.

Impact on Teams Rooms

This configuration ensures third-party meetings appear on the Teams Rooms console with a one-touch “Join” button, mirroring the Teams meeting experience.

Why Other Options Are Incorrect

Set-DeviceConfigurationPolicy (B): Manages device-wide settings (e.g., firmware updates) but not calendar processing.

Set-DeviceTenantPolicy (C): Configures tenant-level device restrictions, unrelated to meeting interoperability.

Set-ResourceConfig (D): Manages resource types in Exchange, not calendar processing for Teams Rooms.

For MS-721 certification, focus on Exchange Online calendar processing for Teams Rooms interoperability.

Example Workflow

# Connect to Exchange Online
Connect-ExchangeOnline
# Configure room mailbox for third-party meetings
Set-CalendarProcessing -Identity "[email protected]" -ProcessExternalMeetingMessages $True -DeleteComments $False

This command enables seamless third-party meeting joins.
