Note : Sensitivity labels can not be applied to emails that have already been sent.
As of May 12, sensitivity labels will be available to all employees with a Microsoft 365 A3 or higher license.
Sensitivity labels can be applied directly within Microsoft 365 applications such as Word, Excel, PowerPoint, and Outlook. However, labels are only enforced on:
Files stored in SharePoint, Teams, and OneDrive
Emails sent through Outlook
Sensitivity labels cannot be applied to files stored outside of these locations.
The following file types are currently supported for labeling:
Word: .docx, .docm
Excel: .xlsx, .xlsm, .xlsb
PowerPoint: .pptx, .ppsx
PDF
Users without an employee A3 or higher license will not be able to apply sensitivity labels. However, they may still see the sensitivity label icon and description in the Office apps.
Available Sensitivity Labels
There are four sensitivity labels available: Public, Confidential, Restricted, and Highly Restricted.
Supported files in employee OneDrives (with A3 or higher licenses) will be automatically labeled 'Confidential' in the weeks following deployment. Document owners are responsible for ensuring the sensitivity label applied to a file accurately reflects the sensitivity of its contents.
No. At this time, sensitivity labels are informational only, assisting users with managing the type of data found in documents.
Only Microsoft Office, OneDrive, SharePoint, and Outlook support sensitivity labels. Outlook is the only mail client where labels can be viewed or added.
Applying a new default sensitivity label to a SharePoint document library does not automatically relabel old documents. Documents must be modified (opened and saved) in order to inherit the new default. The label can also be changed manually within the Details pane (… > Details).
Sensitivity labels that have been applied to PDF documents are only visible in the following locations:
The Sensitivity label column in a SharePoint library. This column is not enabled by default and must be added to your view.
The Details pane (… > Details) in SharePoint and the OneDrive web application.
The Info pane (… > Info) in Microsoft Edge. This option is unavailable when the PDF is launched from OneDrive desktop.
To add an existing column without leaving your list or library:
Navigate to the list or library where you want to create the column.
To the right of the last column name at the top of the list or library, select + Add column or +.
In the pop-up that opens select Show or hide columns.
Scroll down to Sensitivity and check the box to display the column.
Scroll back to the top and select Apply.
Sensitivity labels cannot be viewed in the OneDrive desktop application. The Sensitivity column in OneDrive desktop is unrelated to M365 sensitivity labels.
Sensitivity labels can be added to emails. If an email has attachments, it will default to the same sensitivity label as the attachment.
Labels for meetings and meeting invitations are not available at this time.
When attaching a document with a Restricted or Highly Confidential label, the sensitivity of the email will only update automatically if the document has been attached as a copy and not a sharing link.
Automatic updates to labels based on the sensitivity of attached documents is not supported in New Outlook, Android Outlook, and the Outlook web application on Android.
Yes. If the individual has a Faculty A3 license and has been provided with any level of editing access (Full Control, Design, Edit, Contribute), they will be able to change the label. Individuals provided with Read-only or Restricted view permissions cannot change the label.
Sensitivity labels may not appear immediately in Excel online, in which case, the default label will be applied after some time. Users can override this setting and manually apply a label to the Excel document.
