My OS is Ubuntu 21.10 and my version of Evolution is 3.42.2 (flatpak gitca5e2a1). I have linked my @live.com calender to Evolution with evolution-ews following the directions here. https://www.ubuntudocs.com/kb/gnome-evolution/ I created an event in the @live.com calender in Evolution and then deleted it in Outlook. However it is still showing up in the Evolution calender. If I select it and attempt to delete it with the delete button in the top ribbon I get the error message in the attached picture named evolution2.png. If I open the appointment and attempt to delete it I get the error message in the attached picture named evolution3.png. Can you advise how this appointment can be deleted. Thank you.
