Calender entrys made from W10M don't show up

[Morku]

Hi,

I have a weird problem related to the calender. I upgraded my Lumia 1520 to W10M and made entrys in the calender. They are made into my Outlook calender.
Still after 24 hours, the entrys wont appear in the Windows 10 desktop calender. I also checked in Outlook 2016. No entrys. First I thought the Windows 10 Mobile didn't sync but than I was checking online under calendar.live.com and everything is there. I compared with other entrys, but can't find a different or wrong option.
When I made calender entrys with Windows Phone 8.1 everything displayed fine and synced.
Now I have no idea why other devices don't like my W10M entrys except the browser version. What can I do?

EDIT: Whoops, forget to check the calender in Outlook 2016. It's also there, but still not in the app. I like to use the app, because of live tile.

I'm having the same issue. I can add events from the Mobile app and they show up everywhere else, but it's almost like the app in the phone is dead. Live tile isn't working either. I'm on a 950 XL.

UPDATE [SOLVED]: After deactivating Facebook calendars the live tile started working. Then I tried to add an event, but this time I manually chose which calendar to add the event to. Everything is working now.
