SharePoint Online Calendar Notifactions not working

[Martin_Koetters]

Hello,

we are facing the problem, that for about two weeks all notifications for SharePoint Online calendars have not been working. Before that everything was working fine.

We didn't change any global settings or whatsoever.

I already checked our Exchange logs, if the mails are just being blocked, but that's not the case. It looks like SharePoint is not even sending them out.

Does anyone else face this problem?

Best regards

Martin

Are you talking about SharePoint alerts or SharePoint List Rules or any Power automate flow email notifications or M365/SharePoint group calendar notifications?

Can you share the screenshot how you configured the calendar notifications?

@Martin_Koetters ok.

First of all check if all alerts are still there and correctly configured (daily/weekly, email address settings, etc.). Follow: Manage, view, or delete SharePoint alerts 

If you are still facing this issue, I will suggest you to raise a support ticker with Microsoft directly and report this behavior. Follow: Get M365 Support - Online Support
