I have the same problem. And ist started exactly when I upgraded MS Office to the last version due to the imminent Outlook problem currently exploited by hackers..
Anyway, the version which started that for me is: Microsoft® Word für Microsoft 365 MSO (Version 2301 Build 16.0.16026.20214) 64 Bit
This drives me nuts. I have in the meantime removed the shared calendars of my work colleauges because I did not find a solution. But I cannot work efficiantly that way.
Usually the responses and the hints I found on the internet to this topic (and it seems to be a known issue), only deal with mundane questions (like how to I enable notification, etc.).
People seem not to grasp the problem.
In summary:
- I have added the calendars of my co-workers to my own calendar.
- Until last week, I only got meeting notifications for my own events. That is what i want.
- Since I updatedt Office, I receive, in addition to my own even notifications, also the event notifications of each entry in my co-corkers calendars. This is someting I do not want.
- I have disabled Calendar enhancements in Outlook. That did not solve the issue.
I almost believe that there is clearly a bug (or would microsoft also say "hidden feature"?) of the last Office update.
Any help would be appreciated..
