💡 Our Technical Review in summary
Starting in mid-March 2026, Microsoft is updating the Call Quality Dashboard (CQD) to align its “Meeting ID” dimension with the standard numeric Meeting ID found in Microsoft Teams calendar invites. Historically, CQD used an internal identifier for this field; that legacy value is being moved to a new dimension called “Thread ID” to make room for the more user-friendly numeric ID.
Impact
- Simplified Troubleshooting: IT Admins and helpdesk staff can now search CQD directly using the numeric Meeting ID provided by end-users from their meeting invites.
- Broken Queries: Any existing CQD reports, saved queries, or Power BI dashboards that rely on the current “Meeting ID” dimension will likely fail or return no data because the underlying value format is changing.
- Data Relocation: The alphanumeric strings previously stored in the Meeting ID field will now be found under the “Thread ID” dimension.
- Administrative Workflow: Documentation or internal tools that automate CQD data extraction will require updates to reflect the new dimension mapping.
Action Required
- Audit Existing Reports: Review all custom CQD reports and Power BI templates to identify dependencies on the “Meeting ID” dimension.
- Update Dimension Mapping: For reports that require the legacy internal identifier, update the queries to point to the new “Thread ID” dimension.
- Update Documentation: Revise internal SOPs and helpdesk troubleshooting guides to reflect that searches should now be performed using the numeric ID from Teams invites.
- Notify Support Staff: Inform IT support teams of the change to ensure they are using the correct ID format when investigating call quality issues after mid-March 2026.
- Test Post-Deployment: Once the change is live, verify that scheduled reports are pulling the expected numeric values in the Meeting ID field.

[Introduction]
Beginning in March 2026, you may encounter issues in Call Quality Dashboard (CQD) when searching by Meeting ID. CQD is changing the Meeting ID value to match the numeric Meeting ID found in Teams meeting invites. The previous value used for Meeting ID in CQD will now be found in a separate dimension named Thread ID.
[When this will happen:]
This change will take place starting mid-March 2026.
[How this affects your organization:]
Who is affected:
- Microsoft 365 administrators and IT staff who use CQD.
- Organizations that search for meetings in CQD using Meeting ID.
What will happen:
- CQD will change the Meeting ID value to match the numeric Meeting ID shown in Teams meeting invites.
- The previous Meeting ID value will no longer appear under the Meeting ID dimension.
- The previous value will be available in a new dimension named Thread ID.
- Existing CQD reports or queries that rely on the old Meeting ID may no longer return expected results unless updated.
[What you can do to prepare:]
- Update CQD queries and reports to use the numeric Meeting ID from Teams meeting invites.
- If needed, update reports to use the Thread ID dimension for the previous Meeting ID value.
- Notify helpdesk and support teams about this change.
- Update internal documentation and training materials related to CQD reporting.
