Mailbox Privacy Considerations for Invoice Import

Diagnostic goal: Limit invoice intake to the access, messages, and attachments needed for the documented workflow.

Identify the failure before changing the record

For teams evaluating mailbox-based document capture, the target is to reduce unnecessary exposure while preserving useful context. First determine whether the source is weak, the extracted value is uncertain, the document belongs to another transaction or the workflow context is missing. Correcting a field before identifying the cause can hide the evidence needed to prevent the same error.

Diagnostic 1: Define the minimum mailbox scope

• Expected evidence: Permissions match the feature.
• Failure to rule out: Requesting broader access than needed.
• Resolution: Compare the untouched source with the structured record and document the smallest supported correction.

Diagnostic 2: Review provider permissions and revocation controls

• Expected evidence: Revocation is understood.
• Failure to rule out: Keeping imported mail indefinitely without a policy.
• Resolution: Compare the untouched source with the structured record and document the smallest supported correction.

Diagnostic 3: Avoid importing unrelated message content

• Expected evidence: Retention and sharing are documented.
• Failure to rule out: Sharing mailbox-derived data casually.
• Resolution: Compare the untouched source with the structured record and document the smallest supported correction.

Diagnostic 4: Document how attachments and metadata are retained
