WHY THIS MATTERS Large attachments can fail, fill mailboxes, or expose information to the wrong people. BEST APPROACH Use an approved file-sharing method that allows access control, expiration, and removal of access. BEFORE SHARING Confirm the file is necessary, remove unnecessary sensitive information, name it clearly, and verify recipients. ACCESS SETTINGS Use the least access needed. Prefer specific people over public or anyone-with-link sharing. AFTER SHARING Remove access when the file is no longer needed, especially for confidential or time-limited work.
