Use Sensitivity Labels on Events in New Outlook After Switching From Classic Outlook

You have moved from Classic Outlook to the new Outlook for Windows and now want to apply sensitivity labels to calendar events. In Classic Outlook, you could set a label directly on a meeting or appointment through the ribbon. In new Outlook, the menu layout changed and the option is not in the same place. This article explains where to find sensitivity labels for events in new Outlook and how to apply them correctly.

Sensitivity labels are configured by your organization’s Microsoft 365 administrator. If you could use them in Classic Outlook, they remain available in new Outlook. The difference is the location of the control and the steps to reach it.

You will learn the exact steps to add a sensitivity label to a new event, edit an existing event’s label, and verify that the label appears correctly after sending the invitation.

Where Sensitivity Labels Appear in New Outlook for Events

In Classic Outlook, the sensitivity label control was located in the Tags group on the ribbon of the event window. New Outlook moved this control to a dedicated Sensitivity button in the ribbon. The button is visible only when you are composing or editing an event. It is not available from the main calendar view or from the reading pane.

The label options you see depend on your organization’s sensitivity label policy. Labels such as Confidential, Internal, or Public appear in a dropdown menu when you click the button. If the button is grayed out or missing, your account may not have the required license or the label policy may not include events. Contact your administrator in that case.

New Outlook uses the same Microsoft Purview Information Protection backend as Classic Outlook. Any label you applied to an event in Classic Outlook remains on that event after switching. You do not need to reapply labels to past events unless you want to change them.

Steps to Apply a Sensitivity Label to a New Event

Follow these steps to add a sensitivity label to a new appointment or meeting in new Outlook.

1. Open the calendar and create a new event
   Go to the Calendar module. Click New Event in the top-left corner of the calendar. The event form opens in a separate window.
2. Locate the Sensitivity button in the ribbon
   In the event form, look at the ribbon at the top. The Sensitivity button is in the center of the ribbon, grouped with other options such as Tags. The button shows a shield icon with a lock.
3. Click the Sensitivity button
   Click the button to open the dropdown menu. The menu lists all sensitivity labels that your organization has published for your group or tenant.
4. Select the appropriate label
   Click the label you want to apply, for example Confidential. The button updates to show the name of the selected label. A tooltip may appear explaining the label’s protection rules.
5. Fill in the remaining event details and send
   Add the subject, location, attendees, and any other details. Click Send or Save to create the event. The label is applied to the event on your calendar and, if it is a meeting, to the meeting request sent to attendees.

Steps to Change the Sensitivity Label on an Existing Event

You can change the label on any event you own, including past events. The label cannot be changed on events you did not create unless you have delegate or editor permissions.

1. Open the event from your calendar
   Double-click the event in your calendar. The event form opens in a separate window. If the event is a meeting, you must open the instance or the series.
2. Click the Sensitivity button
   In the ribbon of the event form, click the Sensitivity button. The currently applied label is shown on the button.
3. Select a different label
   Choose a new label from the dropdown menu. The button updates to reflect the new label.
4. Save the event
   Click Save or Send Update if the event is a meeting with attendees. The label change is applied immediately.

If Sensitivity Labels Are Missing or Grayed Out

Several conditions can prevent the Sensitivity button from working correctly. Check these items in order.

The Sensitivity button is not visible in the ribbon

The button may be collapsed into a smaller ribbon. Click the ellipsis (…) at the right end of the ribbon to expand all buttons. If the button still does not appear, your organization may not have published sensitivity labels for events. Contact your Microsoft 365 administrator to confirm that labels are published and that your account is included in the policy.

The Sensitivity button is grayed out and cannot be clicked

This usually means the event was created by someone else and you do not have owner permissions. Open the event and check the Organizer field. If you are not the organizer, you cannot change the label. Ask the organizer to update the label or give you delegate access.

The label does not appear to attendees after sending

Sensitivity labels are applied to the event on your calendar. Attendees see the label only if they have the same label policy and if their Outlook client supports label display. In new Outlook, attendees can see the label in the event details if they open the event. In Classic Outlook, the label may not appear in the calendar grid but is visible in the event form.

Sensitivity Labels in New Outlook vs Classic Outlook for Events

Item	New Outlook	Classic Outlook
Button location	Ribbon of the event form, center area	Ribbon of the event form, Tags group
Label persistence after switching	Labels from Classic Outlook are retained	Labels remain after switching to new Outlook
Editing an existing label	Open event, click Sensitivity, choose new label	Open event, click Tags > Sensitivity
Visibility to attendees	Label visible in event details when opened	Label visible in event details when opened
Requires Microsoft Purview license	Yes	Yes

The location of the Sensitivity button is the only meaningful difference. The underlying label functionality and the protection rules are identical in both versions.

You can now apply and change sensitivity labels on any event in new Outlook using the Sensitivity button in the event form ribbon. If you frequently work with confidential meetings, consider creating a calendar category with the same name as your most-used label to visually identify labeled events at a glance. To apply a label to a recurring series, open one instance of the series and choose Open the series before changing the label so the change applies to all future occurrences.
