Enable or disable calling in a Dynamics 365 Guides environment

Calling in Microsoft Dynamics 365 Guides is enabled by default. When calling is enabled, a Dynamics 365 Guides HoloLens user can call a remote collaborator. The remote collaborator can join the call using Microsoft Teams desktop (PC or Mac) or the Teams mobile app. During the call, the remote collaborator can see everything seen by the Dynamics 365 Guides user, including holograms and the real world behind the holograms.

If you're an admin for Dynamics 365 Guides, enable or disable calling for users in a specific Dynamics 365 Guides environment. Enabling or disabling calling for a specific environment is useful:

  • When operators or authors do not need to work with remote collaborators.

  • You don't want HoloLens users to be able to inadvertently reveal proprietary information through a call.

  4. In the left pane, select Environment, and then move the Enable Calling slider as needed to enable or disable calling for the environment. This action enables or disables the functionality for all configured users signed into that environment. Disabling calling in a Dynamics 365 environment only disables that functionality for Guides and has no impact on that capability in Microsoft Teams.

    If a user tries to start a call while working in an environment where calling is disabled, the user will see the following error message:

    "Your admin may have disabled calling or you may not have a Microsoft Teams or Remote Assist license."
