About directory user review
What Opselith checks
- The user identity column cannot be empty and the same identity should not appear twice.
- UPN/email-like identity columns are checked for a simple address structure.
- If you choose an email column, missing, duplicate or malformed email values are shown for review.
- If you enter an expected sign-in domain, other UPN domains are shown for review rather than automatically treated as wrong.
- If you choose an account-status column, Opselith counts enabled and disabled users and flags values it cannot understand.
What Opselith does not do
This is a file review, not a live directory check. Opselith does not connect to Active Directory or Microsoft Entra and cannot prove whether an account exists in the tenant.
