Supplemental Guidance

Characteristics that identify the status of individuals include contractors, foreign nationals, and non-organizational users. Identifying the status of individuals by these characteristics provides additional information about the people with whom organizational personnel are communicating. For example, it might be useful for a government employee to know that one of the individuals on an email message is a contractor.

Practitioner Notes

This enhancement requires user identifiers to include status information — such as whether the user is a contractor, temporary employee, or has other relevant attributes.

Example 1: Include employment type in Active Directory attributes (e.g., employeeType = "Contractor" or "FTE") and use these attributes in Conditional Access policies.

Example 2: Use a naming convention that includes status indicators — for example, prefix contractor accounts with "CTR-" in your Azure AD to make their status immediately visible.
