Managing business data is harder than ever. Companies deal with emails, files, chats, contracts, and sensitive records every day. Without a clear system, companies can lose important data, delete it by mistake, or keep it longer than needed.

Many companies use Microsoft 365 records management tools to keep data organized and reduce risk. Microsoft Purview records management also helps them meet legal and compliance rules.

This guide explains how records management in Microsoft 365 works and why it matters. It also shows how businesses can build a stronger compliance plan with Microsoft Purview.

Why Microsoft 365 Records Management Matters

Businesses create and store large amounts of information every day. Without a proper system, data can become hard to manage. This can lead to security risks, compliance problems, and higher storage costs.

Microsoft 365 compliance management tools help businesses:

• Keep important records for the right amount of time
• Remove old or unnecessary data
• Apply rules across Microsoft 365 apps
• Lower compliance risks
• Improve daily operations

With Microsoft Purview records management, many of these tasks can run automatically.

Understanding Retention Policies and Labels in Microsoft 365

In Microsoft 365, retention policies and labels help businesses protect data. They also help companies follow compliance rules. The Microsoft Compliance Center uses these tools to manage business information.

Retention Policies and Labels: Guardians of Data

Retention policies and labels stop businesses from losing important Microsoft 365 data. This includes Outlook emails, SharePoint documents, and Microsoft Teams messages.

These tools help organizations:

• Follow company policies and legal rules for keeping data over a set period.
• Reduce risks linked to litigation or security breaches by removing outdated content responsibly
• Improve knowledge sharing by helping users access relevant and updated information

The retention settings in Microsoft 365 records management support different business needs, including:

• Retain-only: Keep content forever or for a set period
• Delete-only: Permanently remove content after a specific time
• Retain and then delete: Keep content for a set period before deleting it permanently

Navigating Retention Settings and Content Interaction

Retention settings help protect content in its original location, even if users edit or delete it. Microsoft 365 automatically keeps copies of retained content across different platforms.

SharePoint and OneDrive

Microsoft 365 keeps copies in the Preservation Hold library to protect important files and documents.

Exchange Mailboxes

Copies stay in the Recoverable Items folder to protect important email records.

Teams and Yammer Messages

Microsoft 365 saves Teams and Yammer message copies in a protected folder.

Revealing Details: Retention Policy vs. Retention Label

Microsoft 365 uses retention policies and labels to manage records and data. Both methods support compliance, but they work differently.

Retention Policies: Container-Level Governance

Retention policies work at the container level. Administrators can apply the same retention settings across entire mailboxes, sites, or locations.

This helps organizations manage compliance across large groups of content more easily.

Retention Labels: Granular Control at Item Level

Retention labels give administrators more detailed control at the item level. This helps when different files or emails need different retention settings inside the same mailbox or location.

Retention labels also move with the content across Microsoft 365. Retention policies stay connected to specific containers only.

Retention labels in Microsoft Purview records management also offer advanced features, including:

• Starting retention from labeling events or event-based triggers
• Using trainable classifiers to identify content automatically
• Applying default labels to SharePoint documents
• Supporting disposition reviews before permanent deletion
• Marking records to provide proof of deletion after the retention period ends

What Are the Rules of Microsoft 365 Retention?

In Microsoft 365 records management, content can use more than one retention policy or retention label at the same time. Microsoft uses retention rules to decide what happens to that content.

Retention Wins Over Deletion Example

An item follows two retention policies:

• Retention policy 1 deletes content after 1 year
• Retention policy 2 keeps content for 2 years

In this case, the longer retention period wins. Microsoft 365 keeps the content for 2 years before deleting it.

Longest Retention Wins Example

An item follows two retention policies and one retention label:

• Retention policy 1 keeps content for 1 year
• Retention policy 2 keeps content for 10 years
• Retention label keeps the item for 2 years

In this case, the 10-year retention policy wins because it has the longest retention period.

This process helps with records retention management and protects important data for the right amount of time.

Explicit Wins Over Implicit for Deletion Example

An item follows:

• Retention policy 1 deletes content after 1 year
• Retention label deletes the item after 3 years

In this case, the retention label wins because it was applied directly to the item. The item gets deleted after 3 years.

Shortest Deletion Wins Example

An item follows two retention policies:

• Retention policy 1 deletes content after 1 year
• Retention policy 2 deletes content after 2 years

In this case, the shorter deletion period wins. The item gets deleted after 1 year.

How to Create and Apply Microsoft 365 Retention Labels

Microsoft 365 records management uses retention labels to manage and organize data.

These labels help businesses follow compliance rules. They also improve records management in Microsoft 365 by applying retention settings correctly.

Note: Users need global administrator or compliance administrator access to create and manage retention labels.

Understanding Retention Labels

Retention labels are an important part of Microsoft 365 records management. They help businesses decide how long content stays saved and what happens to it later.

Step 1: Navigate to the Microsoft 365 Compliance Center

Go to Microsoft Compliance > Records Management > File Plan.

Select “Create a label” to start the process. Add a label name and description that users and administrators can understand easily.

Step 2: Define Label Settings

In the dialog box, enter the label name and description.

This step helps users identify and manage labels more easily.

Step 3: Customize Retention Settings

Set the retention options based on your business needs. Choose:

• How long content stays retained
• When retention starts
• What happens after the retention period ends

You can also add business details for the label. These details are optional and customizable.

File Plan Descriptors Columns

File plan descriptors give businesses more ways to organize and manage labeled content.

Microsoft 365 includes default file plan descriptors such as:

• Business function/department
• Category
• Authority type
• Provision/citation

Define Label Setting

Choose one of these retention settings:

• Retain items forever or for a specific period: Items stay retained for the selected time. After that, Microsoft 365 deletes them from storage.
• Enforce actions after a specific period: Items are not retained. After the selected period, the system can delete or relabel them.
• Just label items: This option only classifies items. Users can still edit, move, or delete them.

Choose What Happens During the Retention Period

• Retain items even if users delete: Users can edit items or remove labels. If users delete items, Microsoft 365 keeps copies in a secure location.
• Mark items as a record: Users cannot edit or delete items. Only admins can change or remove the label.

For SharePoint and OneDrive files, actions depend on whether the record is locked or unlocked.

• Mark items as a regulatory record: Users and admins cannot edit, delete, or remove labels from items. Admins can only increase the retention period or publish the label to other locations.

These settings help improve records retention management and support compliance goals.

Disposition Stages

Disposition stages support content deletion after the retention period ends.

This process helps businesses manage workflows, reviews, and audits before deleting content. Many regulations require this feature.

Disposition review settings work at the label level. Businesses can assign one or more reviewers.

Reviewers only see the content they need to review based on permissions.

Step 4: Review and Create

Review all label details carefully. After that, create the retention label.

Once the label is created, Microsoft 365 shows options for publishing the retention label.

Publishing Retention Labels

Creating labels is only the first step. Businesses must publish labels to use them across Microsoft 365 locations.

Step 1

Go to the Records Management tab. Select Label Policies and click Publish Labels.

Step 2

In the pop-up window, select the labels you want to publish.

Step 3

Admin units help businesses limit policies to specific user groups.

These units also affect location options inside Microsoft Entra ID.

Step 4

Choose whether the policy should be Static or Adaptive.

Step 5

If you select Adaptive in Step 4:

• Click Add Scopes
• Select one or more adaptive scopes
• Choose the locations you want to use

If you select Static in Step 4:

• Choose the locations where the retention labels should apply

This setup helps improve records management in Microsoft 365.

Step 6

Add a name and description for the policy. Review the settings before publishing.

The selected retention labels will then publish across Microsoft 365 locations.

For SharePoint locations, labels usually appear within one or two days.

For Exchange and Microsoft 365 Group locations, labels can take up to seven days to appear in Outlook.

Note

After businesses create and save a retention label or label policy, they cannot change:

• Retention label names
• Policy names
• Scope type (Adaptive or Static)
• Most retention settings
• Record settings

If retention depends on the labeling date, businesses also cannot change the retention period.

Businesses can only delete retention labels that:

• Are not part of retention label policies
• Do not use event-based retention
• Do not mark items as regulatory records

Understanding the Relationship Between Labels and Policies

A retention label can work with many retention label policies. A single policy can also include many labels.

However, auto-apply retention label policies can only use one label.

This setup helps businesses manage labels and improve records management in Microsoft 365.

Publishing Labels

After businesses create labels, they must publish them in the right locations.

Retention label policies decide where Microsoft 365 uses labels and applies them to content.

This process is part of Microsoft 365 records management and helps businesses manage content in different locations.

Conclusion

Creating and applying retention labels in Microsoft 365 takes planning and careful setup.

These steps help businesses manage data and follow compliance rules. They also improve records retention management in Microsoft 365.
