I had a similar experience before a major audit, and following the structure from
45kilo.com made all the difference. The guide covered how to classify emails by project or department, set retention rules that match regulations, and test retrieval speed ahead of time.
They also highlight metadata checks, which I’d never considered but turned out to be essential. After running their “mock audit” checklist, I discovered gaps in our system and fixed them early. The real audit ended up being smooth, and the auditors even complimented how organized and efficient our archive was.
