The user wants to know the definition and possible values of the ShareWithGuests field found in Microsoft Teams raw logs, which is missing from public documentation.

Product: Microsoft Teams
Device & OS: not provided
Scenario: Reviewing or troubleshooting Microsoft Teams raw logs for security, auditing, or compliance purposes.

Before you start

Ensure you have the complete log entry, the date of collection, and the specific product context ready before escalating the issue to Microsoft.

Solution 1Recommended

Submit a Service Request via Microsoft 365 Admin Center

Since raw-log field definitions require internal product information, the best approach is to escalate the query to Microsoft Support.

The 'ShareWithGuests' field is an internal parameter used within Microsoft Teams and Microsoft 365 diagnostic logs. Because Microsoft does not publicly document all raw-log diagnostic fields, obtaining an accurate definition requires direct assistance from Microsoft's technical team.

Gather log information

Collect the complete raw log entry containing the ShareWithGuests field, including the exact timestamp, correlation IDs, and relevant product context.

Contact your Administrator

Reach out to your organization's Microsoft 365 administrator, as they have the required permissions to open official support tickets with Microsoft.

Submit a service request

Have the administrator log into the Microsoft 365 Admin Center, navigate to the Support section, and create a new service request asking for the technical definition of the ShareWithGuests field.

Admin privileges required: Only Microsoft 365 administrators can submit official service requests. Standard users will need to escalate this internally first.
