Admin says “I sent it to you.” Legal says “mine is the revision.” Sales says “the client signed the WeChat version.” Three emails are all named contract. None of them can be the ledger. The taller the inbox, the more it feels like files are under control—you have only hidden the risk in the search box.
The risk is usually versions and access, not a dead hard drive
Email search is strong. Organization is weak. Live contracts, drafts, client returns and lawyer notes sit side by side. Whoever opens first treats it as truth. When someone leaves and the company mailbox closes, policies and contracts vanish—or walk out as a personal forward. In an audit you can produce attachments. You cannot produce “why this version is live, and whether the seal matches.” The role OA plays in compliance: What role OA plays in audit and compliance.
Once seals leave the ledger, email becomes a verbal permit
“Stamp first, email later” is common in small companies. At scale, where the seal went, how many copies, and which perforated pages no longer match a contract number. In a dispute each side holds one email. Put number, expiry and seal count on the same row so renewals are not tribal knowledge—see Once contracts live in one ledger, renewals and seals are not tribal knowledge. If sales, delivery and finance each keep a copy, see Sales, delivery, and finance share contracts: how to split the back office.
Policies fail the same way. The reimbursement standard changed; the old PDF is still pinned. New hires file the old way; finance rejects the new way. A knowledge base needs the current live version, not a museum of attachments. Why files have to become status: Why companies need a management system. DaXi starts with the file type you already get wrong—not an empty document center. Tell us whose inbox holds the contracts on the Management systems service page.
A shared drive and CC-all do not create a live version
Dropping contracts on a shared drive and blasting policies to everyone looks more open than a private inbox. It only copies five “final” files onto more desktops. You still lack: which file is live, who may edit, and who gets the expiry. The wider the CC, the more likely someone uses old terms. If new hires still learn policy by searching mail, onboarding loses a full cycle—see Faster onboarding: the value of a knowledge base and processes. When a mailbox closes at exit, CC history will not restore a single source of truth. Compare How to-dos and permissions survive when a manager leaves.
