Introduction

Data is one of an organization’s most valuable assets. However, organizations must not only protect data but also manage how long it is kept and when it should be deleted. Regulatory requirements, legal obligations, business needs, and security concerns all influence data retention decisions.

Microsoft Purview provides comprehensive retention capabilities that help organizations retain, preserve, review, and dispose of information across Microsoft 365 services. Retention is a key component of information governance and records management.

For the AB-900 exam, it is important to understand the purpose of retention, the difference between retention policies and retention labels, and how Microsoft Purview helps organizations meet compliance and governance requirements.

What Is Retention?

Retention refers to the process of determining:

How long information should be kept
Whether information must be preserved
When information should be deleted
How organizations comply with legal, regulatory, and business requirements

Retention ensures that important information remains available when needed while reducing risks associated with keeping unnecessary data indefinitely.

Examples include:

Retaining financial records for seven years
Preserving employee communications during legal investigations
Automatically deleting outdated project documents
Maintaining business records for compliance purposes

Why Retention Matters

Organizations use retention solutions to achieve several goals:

Regulatory Compliance

Many industries have laws requiring data to be retained for specific periods.

Examples include:

Financial records
Healthcare records
Tax documentation
Legal contracts

Legal Protection

Organizations may need to preserve information for:

Litigation
Audits
Investigations
Regulatory reviews

Information Governance

Retention helps organizations:

Reduce data sprawl
Improve information quality
Eliminate outdated content
Manage storage costs

Security Improvement

Keeping unnecessary data increases risk.

Proper retention practices help:

Minimize exposure to breaches
Reduce attack surfaces
Remove outdated sensitive information

Retention in Microsoft Purview

Microsoft Purview provides retention solutions that work across Microsoft 365 services such as:

Exchange Online
SharePoint Online
OneDrive
Microsoft Teams
Microsoft 365 Groups
Viva Engage
Copilot-related content stored in Microsoft 365

Purview allows organizations to automatically:

Retain content
Delete content
Retain and then delete content

Retention Policies

A retention policy automatically applies retention settings to locations across Microsoft 365.

Administrators create policies that specify:

Where the policy applies
How long content is retained
What happens after the retention period ends

Example

A policy might:

Retain all Teams chat messages for 5 years
Automatically delete them afterward

Advantages

Retention policies:

Apply automatically
Require little user involvement
Work at scale
Provide consistent compliance

Retention Labels

Retention labels provide more granular control than retention policies.

A retention label can be assigned to individual items such as:

Documents
Emails
Files
Records

Labels can be applied:

Manually by users
Automatically by policies
Through sensitive information detection
Through trainable classifiers

Example

A document labeled “Financial Record” could:

Be retained for 7 years
Be declared a record
Be deleted after the retention period expires

Retention Policies vs. Retention Labels

Feature	Retention Policy	Retention Label
Scope	Broad locations	Individual items
User involvement	Usually none	May require user action
Granularity	Location level	Item level
Flexibility	Moderate	High
Records management	Limited	Strong

A useful exam tip is:

Retention policies manage locations, while retention labels manage individual content items.

Retain, Delete, or Retain and Delete

Microsoft Purview supports three primary retention actions.

Retain Only

Content remains available throughout the retention period.

Example:

Retain employee records for seven years.

Delete Only

Content is automatically removed after a specified period.

Example:

Delete temporary files after one year.

Retain and Then Delete

Content is preserved for a retention period and then automatically removed.

Example:

Retain project documents for five years and delete afterward.

Records Management

Records management builds on retention by treating important information as official records.

Organizations can:

Declare content as records
Restrict modifications
Track lifecycle events
Preserve compliance evidence

Examples of records:

Legal contracts
Corporate policies
Regulatory filings
Financial statements

Retention labels are commonly used to manage records.

Retention and Microsoft Teams

Organizations increasingly need to manage communication data.

Purview retention can manage:

Teams chat messages
Channel messages
Meeting content
Shared files

Example:

An organization may retain all Teams conversations for three years to satisfy compliance requirements.

Retention and Exchange Online

Retention can be applied to:

Emails
Mailboxes
Calendar items
Contacts

Example:

All employee email messages are retained for seven years and deleted afterward.

Retention and SharePoint/OneDrive

Retention supports:

Documents
Libraries
Files
Collaboration content

Example:

Project documentation is retained for five years after project completion.

Retention and Microsoft 365 Copilot

Microsoft 365 Copilot uses organizational data stored in Microsoft 365.

Because Copilot accesses existing organizational content:

Retention policies continue to govern underlying data.
Retention labels remain effective.
Information governance policies still apply.
Deleted content generally becomes unavailable after retention requirements are fulfilled.

Organizations should ensure retention strategies are aligned with Copilot usage to maintain compliance and data governance.

Adaptive Scopes

Large organizations often need dynamic retention assignments.

Adaptive scopes allow administrators to target retention policies based on attributes such as:

Department
Geography
User type
Business unit

This reduces administrative effort and improves policy accuracy.

Retention and eDiscovery

Retention supports eDiscovery by ensuring content remains available during investigations.

Benefits include:

Preserving evidence
Supporting legal holds
Maintaining compliance records
Simplifying investigations

Retained content can remain available even if users attempt to delete it.

Retention Best Practices

Organizations should:

Identify regulatory requirements.
Define retention schedules.
Use retention policies for broad coverage.
Use retention labels for specific content.
Regularly review retention settings.
Apply least-privilege administration.
Align retention with records management processes.
Test policies before large-scale deployment.

Introduction

Data is one of an organization’s most valuable assets. However, not all data carries the same level of sensitivity or business value. Some information can be shared publicly, while other information must be protected because it contains financial records, intellectual property, customer data, healthcare information, or confidential business plans.

Microsoft Purview Data Classification helps organizations identify, categorize, and protect sensitive information throughout Microsoft 365. Data classification is a foundational capability that enables organizations to understand their data landscape, apply appropriate protections, meet compliance requirements, and securely adopt AI technologies such as Microsoft 365 Copilot.

For the AB-900 exam, it is important to understand how Microsoft Purview classifies data, the tools involved, and how classification supports security, compliance, governance, and AI readiness.

What Is Data Classification?

Data classification is the process of identifying and categorizing information based on its:

Sensitivity
Confidentiality
Regulatory requirements
Business value
Risk level

Classification allows organizations to answer questions such as:

Which files contain sensitive information?
Where is confidential data stored?
Who can access regulated data?
Which content should be protected or retained?
What data can Copilot safely access?

Microsoft Purview automates much of this process through built-in detection technologies.

Why Data Classification Is Important

Without data classification, organizations often struggle to:

Identify sensitive information
Apply consistent protections
Meet compliance requirements
Prevent data loss
Govern AI access to information

Benefits of data classification include:

Improved data visibility
Better security controls
Regulatory compliance
Reduced risk of data breaches
More effective data governance
Safer use of Microsoft 365 Copilot

Microsoft Purview Data Classification Components

Microsoft Purview uses several components to classify information.

Sensitive Information Types (SITs)

Sensitive Information Types are predefined patterns used to identify sensitive data.

Examples include:

Credit card numbers
Social Security numbers
Passport numbers
Driver’s license numbers
Bank account numbers
Tax identification numbers

Microsoft provides hundreds of built-in SITs covering numerous countries and regions.

Example

A document containing a U.S. Social Security Number may automatically be detected and classified as sensitive content.

Trainable Classifiers

Trainable classifiers use machine learning to identify content based on context rather than exact patterns.

Examples include:

Resumes
Source code
Contracts
Financial documents
Healthcare records
Intellectual property

Unlike SITs, trainable classifiers examine the meaning and context of content.

Example

A contract may be identified even if it does not contain a specific keyword or sensitive number.

Content Explorer

Content Explorer allows administrators to:

View classified content
See where sensitive data exists
Investigate data locations
Analyze classification results

This tool helps organizations understand their data environment.

Activity Explorer

Activity Explorer provides visibility into:

Labeling activities
Classification actions
DLP events
User interactions with sensitive data

Administrators can investigate how classified information is being used.

Types of Data Classification

Organizations typically classify data into categories such as:

Classification	Description
Public	Information intended for everyone
General	Everyday business information
Internal	Information for employees only
Confidential	Sensitive business information
Highly Confidential	Critical or restricted information

Organizations can customize classifications based on their requirements.

Classification and Sensitivity Labels

Data classification often works together with Sensitivity Labels.

Classification identifies the data.

Sensitivity labels protect the data.

Example

Microsoft Purview detects:

Credit card information
Customer account numbers

A sensitivity label is then automatically applied:

Confidential
Highly Confidential

The label can then:

Encrypt the file
Restrict access
Apply watermarks
Block unauthorized sharing

Automatic Data Classification

Microsoft Purview can automatically classify information using:

Pattern Matching

Detects predefined sensitive information.

Examples:

Credit card numbers
Social Security numbers
Passport numbers

Machine Learning

Uses trainable classifiers to recognize content types.

Examples:

Contracts
Legal documents
Source code

Keyword Detection

Identifies content based on specific words or phrases.

Examples:

Confidential
Internal Use Only
Proprietary Information

Data Classification and Microsoft 365 Copilot

Data classification is particularly important for Copilot deployments.

Organizations often ask:

What information can Copilot access?

Copilot respects:

User permissions
Sensitivity labels
Compliance controls

Proper data classification helps organizations:

Understand their data
Identify overshared content
Protect confidential information
Reduce AI-related risks

Classification improves confidence when deploying AI solutions.

Data Classification and Compliance

Many regulations require organizations to identify and protect sensitive information.

Examples include:

GDPR
HIPAA
PCI DSS
SOX
Various privacy laws

Microsoft Purview classification helps organizations:

Locate regulated data
Apply protections
Support audits
Demonstrate compliance

Data Classification and Data Loss Prevention (DLP)

Data classification works closely with DLP policies.

Process

Purview identifies sensitive content.
Content is classified.
DLP policies evaluate the classification.
Protective actions occur.

Examples:

Block file sharing
Restrict email transmission
Alert administrators
Notify users

Without classification, DLP cannot effectively identify sensitive content.

Data Classification and Insider Risk Management

Classified data helps Insider Risk Management identify risky activities involving:

Financial records
Intellectual property
Customer information
Confidential business data

This improves risk detection and investigation capabilities.

Common Data Classification Use Cases

Financial Information Protection

Introduction to Microsoft Purview Sensitivity Labels

Microsoft Purview Sensitivity Labels are classification and protection mechanisms that help organizations secure sensitive information across Microsoft 365. Labels enable organizations to identify important data and apply protections automatically or manually.

Sensitivity labels are part of Microsoft Purview Information Protection and support the principles of:

Data classification
Data protection
Compliance
Governance
Secure collaboration
AI readiness for Microsoft 365 Copilot

Instead of securing locations only, sensitivity labels secure the data itself, allowing protections to remain with content wherever it travels.

Why Sensitivity Labels Matter

Organizations often handle information with varying levels of confidentiality:

Public documents
Internal business data
Financial records
Human resources information
Customer data
Intellectual property
Legal documents

Sensitivity labels provide a consistent method for:

Identifying content sensitivity
Applying encryption
Restricting access
Adding visual markings
Preventing accidental exposure
Supporting compliance requirements

How Sensitivity Labels Work

A sensitivity label can be applied to:

Documents
Emails
Microsoft Teams
Microsoft 365 Groups
SharePoint sites
OneDrive content

Labels can be:

Manually applied

Users choose the appropriate label.

Automatically applied

Microsoft Purview detects sensitive information and assigns labels automatically.

Common Label Hierarchies

Organizations frequently create labels such as:

Label	Intended Audience
Public	Anyone
General	Employees
Internal	Internal users only
Confidential	Specific departments
Highly Confidential	Restricted users

Labels are customizable and vary by organization.

Core Protection Capabilities

A sensitivity label may configure:

Encryption

Controls who can open content and what actions they can perform.

Examples:

View only
Edit allowed
Print blocked
Copy restricted

Content Markings

Visual indicators help users recognize sensitivity.

Examples:

Headers
Footers
Watermarks

Access Restrictions

Limits content access to:

Individuals
Groups
Departments
External users

Expiration Settings

Content access can expire after a specified period.

Major Use Cases for Sensitivity Labels

1. Protecting Confidential Documents

Organizations can label:

Financial statements
Contracts
Product designs
Strategic plans

Example:

A “Highly Confidential” label encrypts a document and restricts access to executives only.

2. Protecting Email Messages

Labels can secure email communication.

Example:

An HR manager sends salary information using a “Confidential – HR” label that:

Encrypts the email
Restricts forwarding
Prevents printing

3. Supporting Microsoft 365 Copilot

Copilot respects existing permissions and sensitivity labels.

If a document is labeled:

Confidential
Highly Confidential
Executive Only

Copilot only uses content that the user already has permission to access.

Sensitivity labels therefore help organizations prepare data safely for AI experiences.

4. Securing External Collaboration

Organizations can share files externally while maintaining protection.

Example:

A company sends a proposal to a partner:

External recipients can read it.
Forwarding is blocked.
Printing is disabled.

Protection travels with the document.

5. Meeting Regulatory Compliance Requirements

Sensitivity labels help support:

GDPR
HIPAA
Financial regulations
Privacy laws
Industry-specific requirements

Organizations can demonstrate that sensitive information receives appropriate protection.

6. Preventing Accidental Data Exposure

Users sometimes unintentionally send sensitive information.

Labels provide:

Classification awareness
Visual reminders
Automated protection

Example:

A user sending customer data receives an automatic recommendation to apply a Confidential label.

7. Protecting Intellectual Property

Engineering designs, research documents, and proprietary information can be restricted.

Example:

Only members of the Research department can access files labeled “R&D Confidential.”

8. Applying Visual Classification

Headers, footers, and watermarks immediately show sensitivity.

Examples:

INTERNAL USE ONLY
CONFIDENTIAL
HIGHLY CONFIDENTIAL

These markings help employees recognize handling requirements.

9. Labeling Containers

Sensitivity labels can be applied to:

Microsoft Teams
Microsoft 365 Groups
SharePoint sites

Container labels can control:

Guest access
Privacy settings
External sharing
Unmanaged device access

Example:

A Team labeled “Confidential Project” automatically disables guest access.

10. Supporting Data Loss Prevention (DLP)

Sensitivity labels integrate with Microsoft Purview DLP.

Example:

A DLP policy may block external sharing of content labeled “Highly Confidential.”

Labels and DLP together provide layered protection.

Manual vs Automatic Labeling

Method	Description
Manual labeling	User chooses the label
Recommended labeling	System suggests labels
Automatic labeling	Purview assigns labels automatically

Automatic labeling reduces reliance on users and improves consistency.

Supported Workloads

Sensitivity labels work across:

Microsoft Word
Excel
PowerPoint
Outlook
Teams
SharePoint Online
OneDrive
Microsoft 365 Groups

Relationship Between Sensitivity Labels and Retention Labels

These labels serve different purposes:

Label Type	Purpose
Sensitivity label	Protect and classify data
Retention label	Govern how long data is kept

Sensitivity labels answer:

“Who can access this?”

Retention labels answer:

“How long should we keep this?”

Benefits of Sensitivity Labels

Organizations gain:

Stronger data protection
Better compliance
Secure AI adoption
Reduced data leakage
Improved collaboration
Consistent classification
User awareness of sensitive data
