Outlook (for macOS) Notifications Stopped Working

KB ID 0001684


Like most of us I spend my working day based around Outlook calendar meetings and entries, I’ve even got birthdays and anniversaries in there. So recently when the notification pop-ups stopped working, it was a potential problem. Occasionally I could hear the notification ‘sound’, but I had to open outlook and change to the notification window to see them. When you are as absent minded as me, that’s a recipe for disaster.

I don’t know if it was a macOS update or a Microsoft Office update that had broken it, (or if I’d done something stupid myself!).


I tried a few solutions but this is the only one that worked. Click the ‘Apple Icon’ (top left) > System Preferences > Notifications > Scroll down and select Outlook > On your keyboard press the ‘Delete/Backspace’ key, to remove Outlook > Close system preferences.

If Outlook is open close it > Open Outlook > At the notification prompt > Click ‘Allow’.

The problem ceased.

  3. Worked great. Only solution so far.
    And, it didn’t ask me to confirm when I restarted. It just started delivering notifications. (just in time. I have a meeting in 10 minutes 🙂

  4. THANK YOU! THiis is the only site that mentioned these steps and it worked for me! I didn’t even have to remove Outlook. It just showed that I had the notifications off for it.
