Treat the email, protected file, access secret and every local copy as separate control surfaces. A successful handoff proves recipient access without claiming that the email provider, protection tool or deletion action controls the others.
01 / DECISIONProtect the attachment without hiding ownership
Retention must cover the sender’s source, staged copy, sent message, recipient download, extracted plaintext and backups. Provider revocation may affect access through a service, but it cannot be assumed to erase copies already downloaded or extracted.
A sender freezes a confidential package for recipient review. The team first proves the workflow with fictional document files, documents each authorized role and preserves the working source separately.
Run the control sequence
- 01
Identify every source, staged, sent, downloaded, extracted and backup copy.
- 02
Assign a retention basis, owner and review date to each required copy.
- 03
Revoke provider access where available and record its actual scope.
- 04
Delete expired local copies using the approved device procedure.
- 05
Confirm exceptions, holds, backups and recipient attestations before closure.
Preserve decision evidence
Record copy location, owner, retention basis, review date, provider revocation result, local deletion action, backup status, hold, recipient response and approver.
Stop when
- A downloaded or extracted copy is missing from the inventory.
- Provider revocation is described as remote deletion of every copy.
- A legal hold, contract or records duty has not been checked.
The record should show the approved package, tested environment, responsible people and known limitations without storing passwords or unnecessary attachment content.
Separate the surrounding controls
Folder Lock secures files before/after transfer; it does not enable Gmail/Outlook native end-to-end encryption. Encryption does not assign provider permissions, verify a recipient, preserve every backup or remove plaintext working copies automatically.
Attachment handoff questions
Should the encrypted archive become the live attachment?
No. Keep the authoritative source in its approved workspace and create one named, verified handoff copy deliberately.
Does resetting a password recover an existing archive?
Do not assume recovery. Record the tool and version, then test a separate recovery copy with fictional files.
