- Topic: Sensitivity labels and label policies (Program)
- Product: Purview, SharePoint, Teams, Exchange
- Stage: Plan
- Last reviewed: October 15, 2026
- Version: 2

## 1. Purpose

Give everyone one simple, shared way to say how sensitive information is, and decide how much the organization will do for them by default. Labels describe sensitivity; label policies decide whether people use them well. Together they are what DLP, encryption and Copilot protections rely on, so a taxonomy people understand and policies that fit how they work are worth getting right before anything is built.

## 2. Overview

Five or fewer labels with plain names, the protection each applies, what label policies do by default, and which applications are in scope.

- Effort: About 10 to 15 person-days
- Duration: 4 to 6 weeks
- Complexity: Medium
- Who's in the room: Information security lead (taxonomy owner), records or privacy officer, legal, Purview admin, communications lead, two or three department representatives
- Beyond E5: Teams Premium for meeting options in labels, and Microsoft 365 Copilot licences for Copilot features, if those are in scope.
- Risk of not doing it: Without agreed labels and policies, departments invent their own markings, protection is applied inconsistently, and the controls that rely on labels have nothing reliable to act on.

## 3. Key activities

### Prerequisites

1. **Gather the rules your labels must reflect** Collect what already defines sensitivity: any classification policy or security marking scheme, privacy obligations, records requirements, and contract clauses on partner or client information. The labels have to satisfy all of them with as few labels as possible, so knowing the list up front avoids a late redesign.
   Who: Information security lead.
   Produces: A one-page inventory of obligations.

2. **Find out what you are protecting** Purview's data explorer shows which sensitive information types already appear across email, SharePoint and OneDrive, and where. Pair it with short conversations with the departments that handle the most sensitive material. You need enough evidence to decide which labels need real protection and which only need a marking.
   Who: Purview admin with the information security lead.
   Produces: A short summary of where sensitive information lives.

### Decisions

3. **Decision: How many labels?** Microsoft notes that labels work noticeably less well when people see more than five main labels, or more than five sublabels under one. It suggests names such as Personal, Public, General, Confidential and Highly Confidential. Use sublabels only where protection differs; a parent label can't be applied by itself, and Microsoft is replacing parent labels with label groups.
   Options: Mirror every existing classification level; Five or fewer main labels, sublabels only where protection differs. Recommended default: Five or fewer main labels, sublabels only where protection differs.
   Who: Taxonomy owner.
   Produces: An agreed list of labels.

4. **Decision: Which labels encrypt?** Encryption travels with the file but limits who can open it, complicates sharing with partners, and Copilot only uses encrypted content when the person has both the VIEW and EXTRACT rights. Permissions the admin defines in the label work better than letting people set their own. Keep encryption for the tier where an unauthorized reader would cause real harm.
   Options: Encrypt every label above Public; Encrypt only the top tier, with admin-defined permissions; No encryption at first. Recommended default: Encrypt only the top tier, with admin-defined permissions.
   Who: Taxonomy owner with legal.
   Produces: A protection setting and reason for every label.

5. **Decision: Which applications are in the first release?** Labels behave differently in each place, and each brings its own requirements. Files and email carry markings and encryption. A label on a site, group or team locks its privacy and controls guests and sharing, and owners can change those settings by changing the label, but the files inside aren't labelled by it. Meeting options in labels need Teams Premium. In Power BI a label protects exported data, not access. Default labels on SharePoint libraries need a plan for which libraries and how their owners are told. Decide what goes first and what follows.
   Options: Everything at once; Files and email first, then sites and groups, then the rest; Files and email only. Recommended default: Files and email first, then sites and groups, then the rest.
   Who: Taxonomy owner.
   Produces: A scoped first release and a list of what follows.

6. **Decision: What do label policies do by default?** Label policies decide what people experience. Microsoft advises as few policies as possible, often one. Recommended defaults: a non-encrypting default label such as General for documents and email; a justification when someone removes or lowers a label (on by default); email recommending its attachment's label; and mandatory labelling only for groups that must label everything, because without a default it frustrates people, and it makes Print to PDF unavailable.
   Options: No default, labelling optional; Mandatory labelling for everyone; Default label and justification; mandatory only where needed. Recommended default: Default label and justification; mandatory only where needed.
   Who: Taxonomy owner.
   Produces: Agreed policy settings.

7. **Decision: Do labels need more than one language?** Label names and tooltips for files and email can be shown in several languages, but you supply the translations; nothing is translated automatically. Labels for sites and groups show only their original language. In a bilingual organization, translate file and email labels and give container labels names that work in both languages.
   Options: One language only; Translated file and email labels; bilingual names for container labels. Recommended default: Translated file and email labels; bilingual names for container labels.
   Who: Taxonomy owner with the communications lead.
   Produces: A language approach for labels.

8. **Decision: Is automatic labelling in scope?** E5 includes automatic labelling, in Office apps and for stored content. It belongs in the Refine stage, once manual labelling is stable, but the decision affects design now: each label that will be applied automatically needs conditions that clearly match it, such as specific sensitive information types.
   Options: Not planned; Planned for Refine; design labels with it in mind; From day one. Recommended default: Planned for Refine; design labels with it in mind.
   Who: Taxonomy owner with the security analyst.
   Produces: A recorded decision and the labels it will cover.

9. **Decision: Who owns the labels?** Labels sit between security, records, privacy and the people doing the work, so they drift when nobody owns them. Name one owner who decides on changes, with records, privacy and legal as reviewers. IT administers labels but shouldn't decide what they mean.
   Options: IT owns and decides; Information security owns; records, privacy and legal review. Recommended default: Information security owns; records, privacy and legal review.
   Who: Executive sponsor.
   Produces: A named owner and reviewers.

### Pilot configuration

10. **Test names and tooltips with real people** Give 15 to 20 anonymized real examples to people from several departments and ask them to pick a label from names and tooltips alone. Where they disagree, the name or tooltip is wrong, not the people. Rewrite until most testers agree on most examples.
   Who: Communications lead with the taxonomy owner.
   Produces: Revised names and tooltips.

### Production configuration

11. **Approve the label and policy specification** Record every label (name, tooltip, protection, priority with the most restrictive last, languages) and every policy setting in one specification, with the first-release scope. Have the owner and reviewers approve it, and hand it to the Prepare stage for testing.
   Who: Taxonomy owner.
   Produces: An approved specification.

12. **Make it enforceable** The decisions become label policy settings: a default label, justification to lower a label, and mandatory labelling where needed. Until they are tested in Prepare and published in Deploy, they are a document, and a document alone doesn't change behaviour. _Partly enforced. The gaps are a risk until a mechanism covers them._

## 4. Approval and readiness

1. **Draft the specification** Labels, protection, policies and first-release scope in one document.
   Move on when: Every label and setting has a reason.

2. **Test names with real people** (Change: Explain) Run the naming test and revise.
   Move on when: Most testers pick the intended label.

3. **Review with legal, privacy and records** Show how each obligation is met.
   Move on when: No open objections.

4. **Approve with the sponsor** (Change: Inform) Fifteen minutes on the labels, defaults and cost of not doing it.
   Move on when: The specification is approved for Prepare.

## 5. Common challenges

- **If you** Copy an existing classification scheme one-to-one. What tends to happen: People face ten labels, pick the first that seems close, and labels stop meaning anything.. A better approach: Keep five or fewer main labels and map the old categories to them in the guide.

- **If you** Encrypt most labels to be safe. What tends to happen: Sharing and co-editing get harder, so people lower labels to get work done.. A better approach: Encrypt only the top tier; protect the rest with markings and DLP.

- **If you** Make labelling mandatory with no default. What tends to happen: Every save and send is interrupted, and people pick whatever closes the prompt.. A better approach: Set a non-encrypting default and ask for a reason only when a label is lowered.

- **If you** Plan in one language for a bilingual workforce. What tends to happen: Half the organization sees labels in a language they don't work in, and container labels can't be translated later.. A better approach: Decide languages now, and name container labels to work in both.

## 6. Checkpoints

**Pilot:**

- [ ] Can testers pick the intended label from names and tooltips alone?
- [ ] Does every encrypting label have a reason and a defined audience?

**Production:**

- [ ] Is the specification approved, with priority order and languages?
- [ ] Are the first-release applications and default settings decided?
- [ ] Is automatic labelling recorded as in or out of scope?

## 7. Success measures

Capture a baseline before you start, or you won't be able to show the change.

- Testers choosing the intended label (Where you see it: Naming test results; Good direction: Up)
- Main labels in the taxonomy (Where you see it: Specification (five or fewer); Good direction: Steady)
- Open objections from legal, privacy and records (Where you see it: Review log; Good direction: Down)

**Ready-to-use text: Label and policy specification columns**

> Label | Tooltip (EN) | Tooltip (FR) | Who it's for | Protection (marking / encryption / who can open) | Priority | Applies to (files, email, sites, meetings, Power BI) | Automatic labelling later (yes/no, conditions) || Policy | Targets | Default label | Mandatory | Justification | Help link

**Ready-to-use text: Tooltip pattern**

> [Label]: for [who can see it]. For example: [everyday example], [everyday example]. This label [adds a footer / restricts who can open the file].
