Summary

"Automatically dismiss reminders for past events" will be enabled by default in the new Outlook for Windows. This change will start rolling out in March 2025 and complete by May 2025. Users can re-enable past-due event reminders in Settings. More information is available [here](https://support.microsoft.com/office/add-or-delete-notifications-or-reminders-in-outlook-7a992377-ca93-4ddd-a711-851ef3597925).

Details

The existing Reminder feature in new Microsoft Outlook for Windows pops up over the user's email or calendar to let them know a scheduled event is about to start. We plan to enable the "Automatically dismiss reminders for past events" option for all users, which will stop reminders from popping up for events that have already passed.

You can re-enable your past-due event reminders by visiting Settings > General > Notifications > expanding the Calendar section > and deselecting Automatically dismiss reminders for past events.


When this will happen:

Targeted Release: We will begin rolling out late March 2025 and expect to complete by late April 2025.

General Availability (Worldwide): We will begin rolling out late April 2025 and expect to complete by early May 2025.

General Availability (GCC): We will begin rolling out early May 2025 and expect to complete by mid-May 2025.

How this will affect your organization:

By default, users will no longer receive Reminder notifications for events that have passed.

What you need to do to prepare:
