Retention Policies for Copilot Content
How to apply Microsoft Purview retention to Copilot interaction data and Copilot-created artifacts. We'll cover what you should retain (and why), how to align retention with government schedules, and how to test that retention behavior works as expected during a Copilot pilot.
Overview
Copilot can dramatically increase the number of drafts, summaries, and interaction records in your environment. But that doesn’t change your retention obligations. It just makes them more important to get right.
Whether you’re deploying in GCC, GCC High, or DoD environments, you need to ensure Copilot-related content is retained or disposed according to agency policy. This video walks you through identifying what content needs retention, aligning your decisions with government records schedules, configuring Microsoft Purview to enforce those decisions, and validating everything with pilot testing.

Hook: Copilot changes volume, not your obligations
Copilot can dramatically increase the number of drafts, summaries, and interaction records flowing through your environment.
Think about it. Every prompt. Every response. Every document Copilot helps write. That’s new content hitting your systems at a pace we haven’t seen before.
But here’s the thing: that volume doesn’t change your retention obligations. Your agency still has records schedules. You still have legal hold requirements. You still need to demonstrate compliance to auditors and oversight.
What changes is this: getting retention right just became a lot more important. Because if you don’t configure it intentionally, you’re going to end up with either too much data you can’t manage or missing records you legally needed to keep.
So let’s fix that.
What content you’re managing
When we talk about retention for Copilot, we’re talking about two categories of content.
First, there’s Copilot interaction content. That’s the prompts users enter, the responses Copilot generates, and the citations it provides. Depending on your environment and configuration, this data lives in Microsoft 365 as part of the service architecture.
Second, there’s Copilot-assisted outputs. These are the actual documents, emails, SharePoint pages, and Teams messages that Copilot helps users create. Once those artifacts are saved to their normal locations—SharePoint, Exchange, OneDrive—they’re just regular Microsoft 365 content.
Here’s the key framing line you need to remember: retention is about the business record, not whether a human or Copilot helped write it.
If a document is a federal record under your agency’s schedule, it doesn’t matter if a person typed every word or if Copilot drafted the outline and a human refined it. The retention requirement is the same. The record is the record.
That simplifies a lot of your decision-making. You’re not inventing new retention categories. You’re applying your existing records policy to content that happens to involve Copilot.
Choose your retention strategy
Now let’s talk about how to actually decide what to retain and for how long.
You’re going to align your decisions to agency schedules and legal requirements. That’s non-negotiable. Start with your records officer and your legal counsel. They’ll tell you what’s required.
Then you need to make three decisions.
First, what content types are in scope? Are you retaining Copilot interaction content itself, or just the final outputs? Some agencies want to keep prompts and responses for oversight or investigation purposes. Others decide interaction content isn’t a record and only retain final work products.
Second, what’s your minimum retention period? Even for content that isn’t a permanent record, you may need to keep it long enough to support investigations, audits, or Freedom of Information Act responses. Work with your general counsel to define that floor.
Third, what are your disposition rules? Where the law and your schedules allow it, you’ll want to define when content can be deleted. Retention isn’t just about keeping things. It’s also about disposing of records appropriately when their retention period expires.
Here’s the government callout you need to hear: make sure records, counsel, and security agree on the retention posture before rollout. Changing retention policies after you’ve deployed Copilot to thousands of users is painful. Get alignment up front.
Implement in Purview
All right. You’ve made your retention decisions. Now let’s configure Microsoft Purview to enforce them.
You’re going to use retention policies and retention labels. Policies apply automatically to entire locations like Exchange, SharePoint, or OneDrive. Labels let users or automated rules classify individual items.
Here’s what you need to configure.
First, identify the locations where Copilot content lives. For Copilot-assisted outputs, that’s your standard Microsoft 365 workloads—Exchange mailboxes, SharePoint sites, OneDrive accounts, Teams channels. You probably already have retention policies covering these.
For Copilot interaction content, Microsoft’s documentation tells you where that data resides and whether it’s in scope for retention policies. Review that documentation for your specific environment—GCC, GCC High, or DoD—because the architecture can differ slightly.
Next, create or update your retention policies to cover those locations. You can set a retention period, configure whether to retain only or retain and then delete, and define any exceptions for specific sites or users.
If you’re using retention labels, make sure they’re published to the right apps and users. Labels give you flexibility for content that needs different treatment—maybe classified work products get seven years, while drafts get two.
Now here’s the critical part: you need a testing plan.
Before you roll retention policies to your full population, create known Copilot interactions and artifacts in a pilot environment. Generate some prompts in Copilot. Save some documents. Let the retention period start.
Then validate three things. First, does the retention behavior work as expected? Are items being retained according to your policy? Are they being deleted when they should be?
Second, is the content visible in eDiscovery and content search when you need it? Retention doesn’t help if you can’t find the content during an investigation or legal hold.
Third, can you explain what’s happening to an auditor? You should be able to show the policy configuration, demonstrate the behavior, and map it back to your agency’s records schedule.
If your test plan passes, you’re ready to deploy. If it doesn’t, fix it before you go production.
Close: what to document
Let’s wrap with what you need to document for your governance package.
First, document your scope decisions. What content types are you retaining? What did you explicitly decide not to retain, and why?
Second, document your retention periods. Map them back to your agency records schedules or legal requirements. Show the line of reasoning.
Third, document the Purview locations you’ve configured. List the policies, the labels, and the workloads they cover.
Fourth, include your pilot test evidence. Show that you validated retention behavior in a controlled environment before deploying.
This documentation becomes part of your governance package for GCC, GCC High, or DoD approvals. Your authorizing official wants to see that you thought this through. Your auditors want proof you tested it.
And when the next oversight question comes—and it will—you’ll have a defensible answer ready to go.
That’s retention for Copilot content. Align with your schedules. Configure with intention. Test before you deploy. Document everything.
