Investigate sharing issues

Completed

Sharing is commonly used in online meetings. The organizer, or another authorized participant, might want to share the following elements:

• An entire screen
• A single application
• PowerPoint slides
• Whiteboard
• Shared notes

When users experience problems with initiating shared content in a meeting, review the meeting policies assigned to the organizer and participants. Also review the meeting settings.

Review content sharing policy settings

To review the content sharing settings, open the Microsoft Teams admin center, and review the Content sharing section of the appropriate meeting policy, as shown in the following screenshot.

The following table describes content sharing policy settings.

Setting	Description
Screen sharing mode	Enables you to define the screen sharing mode. Options are Entire screen or Single application. Ensure that Disabled is not selected. This is a per-organizer and per-user setting.
Allow a participant to give or request control	Determines whether a user can give control of the shared desktop to other participants in the meeting. This per-user setting determines whether the Give Control button is accessible during a meeting.
Allow an external participant to give or request control	Determines whether external participants can be given control or request control of the sharer's screen. This is a per-user setting.
Allow PowerPoint sharing	Determines if a user can share PowerPoint slide decks in a meeting. External users, including anonymous, guest, and federated users, inherit the policy of the meeting organizer. This is a per-user setting.
Allow whiteboard	Determines if users can use and share the whiteboard during their meetings.
Allow shared notes	Determines if a user can create and share notes in a meeting. External users, including anonymous, B2B, and federated users, inherit the policy of the meeting organizer. This is a per-user setting.

When considering the effect of policies, remember that per-organizer and per-user policies can sometimes be confusing. Let’s review a couple of examples.

Screen sharing example

Screen sharing mode is a per-organizer and per-user policy. Let’s imagine your global meeting policy allows for Entire screen sharing. However, Adele is assigned a policy with Disabled screen sharing. If Alex schedules a meeting, then anyone that joins the meeting can share their screens or apps. If Adele joins, she cannot share her screen or apps. If Adele schedules a meeting, then no one can share their screen or apps.

Give or request control example

The Allow a participant to give or request control setting is per-user only. Let’s imagine that your global meeting policy has this value On. However, Adele is assigned a policy where this value is Off. If Alex schedules a meeting, he can give control of the shared desktop to other participants. If Adele schedules a meeting, she cannot give control of the shared desktop to other participants. However, if Alex attends that meeting, he can give control.

Tip

You can use the Set-CsTeamsMeetingPolicy PowerShell cmdlet to configure these policy settings.

Verify network settings

Specific network ports must be accessible for screen sharing in Teams. These can be reviewed or managed in the Meeting settings page in the Microsoft Teams admin center. For sharing, the default network ports are: 50040 to 50059.
