Question

Meeting Reminder now showing on the new outlook

Byung Seo 0

Meeting Reminder works on the classic O365 outlook, outlook web mail and also on user's mobile phone outlook.

When user switched from classic desktop outlook to new desktop outlook on her laptop, it stopped showing Reminder.

When we checked Reminders pop up screen, it was showing You are all caught up! You have no new reminders.

What is the issue and how can we fix this issue?

Thanks,

Dear @Byung Seo,

Thank you again for reaching out and for keeping me updated on your situation.

If you have already checked the New Outlook settings in both the web and desktop versions and the issue still persists after following my suggestions, I recommend creating a Microsoft support ticket via Microsoft 365 Admin Center > Support > Help & Support for further investigation.

Note: If you are an end-user, please reach out to your IT administrator and ask them to create the support ticket on your behalf.

As a forum moderator, I do not have access to detailed logs or backend systems due to privacy and security limitations. Because of this, contacting Microsoft Support directly is the most effective way to move forward.

A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.

I hope this helps and I wish you a smooth and quick resolution.

Thank you again for your detailed follow-up, as well as your patience and understanding throughout this troubleshooting process.

Dear @Byung Seo,

Good day, and I appreciate the clear explanation of your concern.

Since reminders are working in Classic Outlook, Outlook on the web and mobile, this confirms the mailbox and calendar are functioning correctly. When the issue happens only in New Outlook for Windows, it is typically caused by local notification or Windows system settings blocking reminders, even though they still exist on the server.

Please see the following workarounds that will help you verify the issue:

Ensure that your Windows system and the Outlook application are fully up to date.

Option 1: Verify reminder notifications in New Outlook

Open New Outlook > Select Settings (gear icon) > Go to General > Notifications.

Under “Notify me about” > Select Calendar.

User's image

Turn Calendar notifications On > Expand Calendar > Set the notification style to Reminder (popup).

Enable sound if desired.

This ensures New Outlook is allowed to display reminder pop-ups.

Option 2: Confirm reminders are set on calendar events

In New Outlook, open Settings.

Go to Calendar, then Events and invitations.

Under “Events you create", set a Default reminder value such as 15 minutes.

Next, check an affected meeting directly.

Open the meeting from the calendar.

Confirm the Reminder field is set to a time value and not “Don’t remind me”.

This confirms reminders are configured correctly for both new and existing meetings.

Option 4: Check Windows notification settings

On the laptop, open Windows Settings > Go to System > Notifications.

Make sure “Get notifications from apps and other senders” is turned On.

Confirm Do Not Disturb is Off.

Scroll to the app list and select Outlook.

Make sure notifications are allowed, including banners and sounds if required.

Note: If any notification options are greyed out, they may be controlled by device or organizational policy. In that case, an administrator would need to allow notifications. In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support

For Windows 10 and Windows 11, you can use the Microsoft support article below to review notification and Do Not Disturb settings: Notifications and Do Not Disturb in Windows - Microsoft Support

Option 5: Check Focus sessions and Battery Saver

Open Windows Settings > Go to System > Focus.

Make sure no focus session is currently active.

Then check Battery Saver.

Go to System, then Power and battery > Turn Battery Saver Off.

Both features can temporarily suppress notifications.

Option 7: Repair the New Outlook app
