Internatl Error: Unsupported Property
When I try to open a recurring appointment in Outlook 2019, I'm suddenly getting an error message "Sorry, we're having trouble opening this item. This could be temporary, but if you see it again you might want to restart Outlook. internal error: Unsupported Property.
What is this?

I have the same error, which is persistent despite restarting my computer several times. Did you manage to solve it?
