Using New Outlook on Windows for professional communication and productivity
For new Outlook for Windows, the most relevant checks are these:
- Verify reminder notifications are enabled in new Outlook
- Go to Settings > General > Notifications.
- Under Notify me about, expand Calendar.
- Turn notifications On.
- Select a reminder style such as a popup reminder, and enable sound if needed.
- If reminders for older items are being cleared automatically, check whether Automatically dismiss reminders for past events is turned on.
- Verify a reminder is actually set on the items
- For all calendar events: go to Settings > Calendar > Events and invitations.
- Under Events you create, check the Default reminder value.
- Open one affected meeting and confirm its Reminder value is not set to Don’t remind me.
- For tasks: open To Do, select the task, and confirm Remind me is set.
- Check Windows and Teams conditions that suppress notifications
- Windows settings such as Notifications, Focus Assist, or Do not disturb can interfere with Outlook notifications.
- If Microsoft Teams is in Do not disturb, Outlook notifications can also be affected.
- If the reminders pane stays empty, test with a newly created event
- Create a new calendar event a few minutes in the future.
- Set an explicit reminder time.
- Save it and check whether it appears in the reminders window and triggers a notification.
- If existing items fail but new items work, open the affected meetings individually and re-save their reminder setting.
- If reminders still do not appear, reset the reminder state in classic Outlook only if available
- For Outlook reminder corruption, Microsoft documents
outlook.exe /cleanremindersfor Outlook. - This is intended for Outlook reminder issues such as reminders that cannot be dismissed or keep reappearing.
- For Outlook reminder corruption, Microsoft documents
- If using Outlook on the web as a comparison test
- In Outlook on the web, notifications only appear while Outlook is open in the browser.
If the issue is specifically that the Reminders window is always empty even though meetings and tasks have reminders configured, that points to reminder processing not working correctly in the app rather than just a notification banner setting. In that case, the supported checks from the documentation are: confirm Settings > General > Notifications > Calendar is enabled, confirm each item has a reminder set, and rule out Windows or Teams suppression.
