After you create your labels, you’ll want to verify that they’re being applied to content as you intended. With the data governance reports in the Office 365 Security & Compliance Center, you can quickly view:

You can see each label’s count, location, how it was applied, its retention actions, whether it’s a record, and its disposition type.
Manual vs Auto apply This report shows the count of all content that’s been labeled manually or automatically, and the percentage of content that’s been labeled manually vs automatically.
