Graph /users query with mailboxSettings filters/expands excludes unlicensed users
Hello Microsoft Graph team, I would like to report what appears to be a bug in Microsoft Graph user queries involving mailboxSettings. Issue summary: When mailboxSettings is used in a filter or expand clause on /users, unlicensed users are not returned, even when they should match the filter. Example scenario: Filter used: mailboxSettings/userPurpose ne 'room' Observed behavior: Users without Exchange license/mailbox are excluded from results (or result set appears truncated to mailbox-enabled users). Expected behavior: All users should be considered in /users query evaluation. If a user has no mailbox settings, behavior should be consistent and documented (for example null handling), but those users should not be silently dropped from /users results unless explicitly filtered out by query semantics. Reproduction steps: In a tenant with mixed users: Licensed mailbox users Unlicensed users without mailbox Run a /users query that includes mailboxSettings in filter and/or expand. Compare returned users with a baseline /users query without mailboxSettings conditions. Notice unlicensed users disappear when mailboxSettings is involved. Sample request patterns: GET https://graph.microsoft.com/v1.0/users?$filter=mailboxSettings/userPurpose ne 'room' GET https://graph.microsoft.com/v1.0/users?$expand=mailboxSettings&$filter=mailboxSettings/userPurpose ne 'room'
