The final file has been delivered, but an outside project group can still access the working folder. Forgotten permissions are common because visible completion and technical access management are separate tasks. Plan a short closeout review that allows the required handover and then removes access no longer needed for the finished assignment.
Verify handover before removal
Establish which outputs must remain with the project and who will manage them. Files in a departing person's personal account may need an organized handover. Do not revoke the only access before that issue is resolved. Verify the readability and completeness of the transferred material.
Distinguish working files, approved outputs, and personal notes. Access need not end everywhere simultaneously. A limited correction period may justify a documented exception. Record its purpose, scope, and review date instead of leaving an indefinite permission in place.
Look beyond individual invitations
Check direct invitations, group memberships, and general sharing links. Removing someone from a file share may leave access through a parent group. Google Drive highlights the role of parent-folder permissions. Review the actual access routes in the service you use.
Also consider guest accounts, project boards, calendars, and connected applications. An access token or integration may remain independently of a visible folder share. Work through a short list of services used by the project. Remove only access whose scope is understood so other active projects are not affected accidentally.
Record the outcome and its limits
Review the access overview again after changes. Important areas may warrant an appropriate recipient-side test. Record the date, services checked, and remaining exceptions. A concise traceable closeout note is more useful than simply saying everything has been cleaned up.
Revoked permissions do not erase copies already downloaded. Their handling needs a separate agreement and, where appropriate, confirmation. Future projects benefit from time-limited access, clearly defined groups, and an identified owner. Closeout then becomes a normal final task rather than a later investigation.
