How to use the Microsoft data classification dashboard
As a Microsoft 365 administrator or compliance administrator, you can evaluate and then tag content in your organization in order to control where it goes, protect it no matter where it is, and ensure that it is preserved and deleted according to your organization's needs. You do this through the application of sensitivity labels, retention labels, and sensitive information type classification. There are various ways to do the discovery, evaluation, and tagging, but the end result is that you may have very large numbers of documents and emails that are tagged and classified with one or both of these labels. After you apply your retention labels and sensitivity labels, you'll want to see how the labels are being used across your tenant and what is being done with those items. The data classification page provides visibility into that body of content, specifically:
- the number items that have been classified as a sensitive information type and what those classifications are
- the top applied sensitivity labels in both Microsoft 365 and Azure Information Protection
- the top applied retention labels
- a summary of activities that users are taking on your sensitive content
- the locations of your sensitive and retained data
You also manage these features on the data classification page:
- trainable classifiers
- sensitive information types
- Learn about exact data match based sensitive information types
- content explorer
- activity explorer

Data classification will scan your sensitive content and labeled content before you create any policies. This is called zero change management. This lets you see the impact that all the retention and sensitivity labels are having in your environment and empower you to start assessing your protection and governance policy needs.
In order to get access to the data classification page, an account must be assigned membership in any one of these roles or role groups.
Microsoft 365 role groups
- Global administrator
- Compliance administrator
- Security administrator
- Compliance data administrator
As a best practice, always use the role with least privilege to grant access to Microsoft 365 data classification.

Sensitive information types used most in your content
Microsoft 365 comes with many definitions of sensitive information types, such as an item containing a social security number or a credit card number. For more information on sensitive information types, see Sensitive information type entity definitions.
The sensitive information type card shows the top sensitive information types that have been found and labeled across your organization.
To find out how many items are in any given classification category, hover over the bar for the category.
If the card displays the message "No data found with sensitive information", it means that there are no items in your organization that have been classified as being a sensitive information type or no items that have been crawled. To get started with labels, see:
Top sensitivity labels applied to content
When you apply a sensitivity label to an item either through Microsoft 365 or Azure Information Protection (AIP), two things happen:
- A tag that indicates the value of the item to your org is embedded in the document and will follow it everywhere it goes.
- The presence of the tag enables various protective behaviors, such as mandatory watermarking or encryption. With end point protection enabled you can even prevent an item from leaving your organizational control.
For more information on sensitivity labels, see: Learn about sensitivity labels
Sensitivity labels must be enabled for files that are in SharePoint and OneDrive in order for the corresponding data to surface in the data classification page. For more information, see Enable sensitivity labels for Office files in SharePoint and OneDrive.
The sensitivity label card shows the number of items (email or document) by sensitivity level.
If you haven't created or published any sensitivity labels or no content has had a sensitivity label applied, this card will display the message "No sensitivity labels detected". To get started with sensitivity labels, see:
Top retention labels applied to content
Retention labels are used to manage the retention and disposition of content in your organization. When applied, they can be used to control how long an item will be kept before deletion, whether it should be reviewed prior to deletion, when its retention period expires, and whether it should be marked as a record. For more information, see Learn about retention policies and retention labels.
The top applied retention labels card shows you how many items have a given retention label.
If this card displays the message, "No retention labels detected", it means you haven't created or published any retention labels or no content has had a retention label applied. To get started with retention labels, see:
Top activities detected
This card provides a quick summary of the most common actions that users are taking on the sensitivity labeled items. You can use the Activity explorer to drill deep down on the different activities that Microsoft 365 tracks on labeled content and content that is located on Windows 10 endpoints.
If this card displays the message, "No activity detected" it means that there's been no activity on the files or that user and admin auditing isn't turned on. To turn the audit logs on , see:
Sensitivity and retention labeled data by location
The point of the data classification reporting is to provide visibility into the number of items that have which label as well as their location. These cards let you know how many labeled items the are in Exchange, SharePoint, and OneDrive etc.
If this card displays the message, "No locations detected, it means you haven't created or published any sensitivity labels or no content has had a retention label applied. To get started with sensitivity labels, see:
Public preview release notes
Exchange mailbox count: You will notice a small tool tip appear when you drill into Exchange mailboxes. This is to call out the fact that the aggregate count displayed for sensitive information type, sensitivity label and retention label may not exactly match the number of items that you will find inside the mailbox. This is because the drill-down into the folder fetches the live view of content, which is classified, while the aggregated count is calculated.Information the user should notice even if skimming
Rendering of encrypted documents: SharePoint, Exchange, and OneDrive files that are encrypted don't render in the content explorer. This is a sensitive issue that requires a balance between the need to see file contents in content explorer and the need to keep the contents encrypted. With the permissions granted by Content Explorer List Viewer, and Content Explorer Content Viewer role groups, you will see a list view of the files, the file metadata, and a link you can use to access the content via the web client.Information the user should notice even if skimming
Supported characters in retention label names in SharePoint search:
SharePoint search doesn't support retention label names with
_ in them. For example,
Label_MIP aren't supported. SharePoint search does support those characters in sensitivity label names and sensitive information type names.
OneDrive remains in preview: Thanks for your valuable feedback on OneDrive integration during our preview program. As we work through the specifics, you may run into inconsistent data / flows. We'll continue to showcase OneDrive in preview until all fixes are in place. We appreciate your continued support.
