Hi Team,

Could please provide the following details regarding the Teams Rooms Pro Management Portal Incident Notification Webhook Integration?

Reference: https://learn.microsoft.com/en-us/microsoftteams/rooms/pmp-incident-webhook-integration

A. Known Limitations / Hard Caps for Device Monitoring via Webhook Configuration

Could you please confirm whether there are any documented or undocumented limits related to configuring devices for monitoring through the Incident Notification Webhook integration, specifically:

  1. Maximum number of devices supported
  2. Maximum number of device groups supported
  3. Maximum number of devices that can be included within a device group

B. GA Status Confirmation for Teams Rooms Pro Management Portal Incident Notification Webhook Integration

  1. The Pro Management Portal UI currently lists this capability as Preview. Could you please confirm whether this feature has reached General Availability (GA)? If yes, could you share any publicly available Microsoft documentation confirming its GA status?
  2. If the feature is not yet GA, could you please provide the current roadmap or expected timeline for GA availability?

Additional Context

For the TAC Device State Rule Webhook Notification capability:

https://learn.microsoft.com/en-us/microsoftteams/alerts/device-health-status

We have previously encountered a limitation when onboarding more than 1,000 devices for monitoring. Microsoft confirmed that this is a product-side hard cap by design, although this limitation is not currently documented in any public Microsoft article and microsoft has agreed this is documentation gap.

Given this experience, would appreciate clarification on whether similar hard limits exist for the Teams Rooms Pro Management Portal Incident Notification Webhook Integration.

I would greatly appreciate your guidance and a quick response on the above points.

Thank you.

    Hi Devendra,

    I greatly appreciate the detailed information about your concern.

    Based on the currently available Microsoft documentation, the only numerical limit documented for the Teams Rooms Pro Management Portal Incident Notification Webhook Integration is a maximum of 10 integrations per portal. The documentation does not specify a maximum for:

    • Devices included in a webhook configuration
    • Device groups included in a webhook configuration
    • Devices contained within a device group

    The configuration supports selecting multiple rooms or room groups, but no corresponding device or group capacity limit is publicly documented. Since there is no official article or documentation confirm that the service has no backend hard cap, I cannot provide an unsupported assurance that the integration can monitor an unlimited number of devices.

    As of now, the accurate information I can confirm includes:

    • Documented hard limit: 10 integrations per portal
    • Maximum devices per integration: Not publicly documented
    • Maximum groups per integration: Not publicly documented
    • Maximum devices per group: Not publicly documented

    For the best possible assistance for your concern, I highly recommend reaching out to your IT administrator and ask them to raise a support ticket with Microsoft Support through the Microsoft 365 Admin Center for deeper investigation. They have access to backend configurations and can perform a more in-depth investigation. At the very least, they can provide the most effective workaround to ensure your experience remains smooth and secure. 

    I hope this helps point you in the right direction. If you have any updates or additional questions, feel free to reply back and I'll do my best to assist further.

    Based on the documented information available for Teams Rooms Pro Management Portal Incident Notification Webhook Integration:

    • The only explicitly documented hard limit for the webhook integration itself is that only 10 integrations can be created from a single portal.
    • The documentation does not provide any published limit for:
      • maximum number of devices supported by a webhook configuration
      • maximum number of device groups supported
      • maximum number of devices within a device group
    • The setup flow documents event subscription filters such as Device Type, Ticket State, and Ticket Severity, but it does not document device-count or device-group-count caps.

    For GA status:

    • The available documentation describes the feature and setup, but it does not state that the Incident Notification Webhook Integration is General Availability.
    • No public GA confirmation or GA announcement is present in the available documentation.
    • No public roadmap or GA timeline is provided in the available documentation.

    Other documented limitations that do exist:

    • Available only in Commercial and GCC.
    • GCC-High and DoD are not supported for this webhook integration.
    • Not available in the Teams Rooms Multitenant Management Portal.
    • Customers must host their own endpoint and manage payload transformation and authentication.

    So, for the specific questions raised:

    1. Maximum number of devices supported: not documented.
    2. Maximum number of device groups supported: not documented.
    3. Maximum number of devices in a device group: not documented.
    4. GA status: not confirmed in the available public documentation.
    5. GA timeline / roadmap: not documented.
