Cannot create recurring calendar meeting

Calendar

I’m trying to create a recurring calendar meeting and getting this error dialog when I try to save it:

So kind of a useless error message.

Any hints as to what’s wrong?

More info: I converted it from an online meeting to a standard meeting and was at least able to save it. So it has something to do with creating an online meeting.

But IMO the error message should give more information about the error and how to fix it.

I’m running version 10.1.4588 (f11e2ab).
