I'm on outlook 365 Mac. I have 5 emails (in my email account) but only 4 of these emails are in my calendar tab (event). There isn't a option anywhere to make this 1 email to be visible in the calendar tab. I can see events if I search them. I was on a call with microsoft support this morning and we were getting nowhere even though he was very patient and was trying very hard to figure this out. I just deleted the email account and reloaded it, but it still doesn't populate into the calendar tab. If I go into accounts under tools you would think if I clicked on to the account there would be an advanced button but there isn't. You would think that there would be a place to show what you want to see from each email like if your a b c @ d e f . c o m you don't want to show todo's the there should be a place to check a box.
