I think from the function-side this behavior is correct ... if you use some log reader software - you may fade the calendar-requests out 😁 ...but I think we should not change that?!

Generally the Problem is not, that the admin_audit records the requests, the problem is: The requests are there 😜 @LukasReschke

Thanks, so maybe a different, more fine grained log level system might be interesting then.
I don't know if this suggestion is serious or feasable, just popped into my head.

But I will also look into that Calendar App on MacOS, since this is the only user that generates these many entries. Got to see what happens when more people wake up from their vacation.

Thanks again!
