Document Retention Plan
Implementation

The Problem

Every organization needs a retention policy — but most have either
nothing in place or a policy that exists only on paper. Meanwhile, old,
outdated, or sensitive content accumulates across SharePoint, OneDrive,
Exchange, and Teams. With Copilot now surfacing content across the
tenant, retention hygiene is no longer optional. Content that should
have been purged is one query away from being surfaced to anyone with
access.

What This Covers

Working retention plans implemented in Microsoft Purview that
automatically classify, retain, and dispose of content according to your
business and regulatory requirements. Not a policy document — an actual
working system.

What’s Included

• Retention labels and policies configured in
  Microsoft Purview
• Auto-apply rules based on content type,
  sensitivity, or location
• Disposition review workflows for records that need
  human sign-off before deletion
• Documentation of your retention schedule for
  compliance audits

Why Now

Copilot changes the calculus. Before AI search, buried content was
buried — bad practice but low risk. Now every piece of content in your
tenant is queryable by every user with access. A 5-year-old draft
contract with wrong terms, a sensitive HR document in an overshared
site, an outdated policy that contradicts current guidance — all of it
is now one natural-language query away from surfacing.

Architectural Approach

I start with a content audit: what types of content exist, where they
live, what retention requirements apply (regulatory, legal hold,
business policy). From there, I design a label taxonomy, configure
auto-apply rules, set up disposition workflows, and document everything
so your compliance team can explain the system to auditors. The goal is
a retention plan that runs itself — not one that depends on people
remembering to delete things.
