Calendar events created from apple mail is missing email reference
When an Apple Calendar event is created from a time/date appearing in an email message (Apple Mail) (I am using MacOs 10.14.2) I do not get a email message reference (URL) in the created event. My problem is that I would like to be able to go back to the email straight from the event. This used to work fine and a link to the original email message was always included when I created events from inside emails. For some reason this stopped working (long ago now, on OSX ). Any help would be most appreciated!
