Original GitHub issue: https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/447

The birthdays are marked with a special tag eventType which is set to 'birthday'.
https://developers.google.com/calendar/api/guides/event-types

They are synced correctly to my Outlook calendar.
But they then sync back to google removing that tag screwing with the Google Calendar.
They are then regular events and not longer birthday events.

Green is my regular calendar with an item that's been synced back.
Test is a new item created as birthday before being synced.

Is it possible to exclude the birthdays from syncing through an advanced setting?
