I've a Samsung Galaxy A5 (2016) with Android 6.0.1
I've added recently my Microsoft Live account to it as MS ActiveSync to be able to synchronize calendar (Samsung S-Planner).
The calendar is synchronized correctly, however I can't hide birthdays and national holidays.
I want to see only my appointments, and not all those community ones.
For other accounts on my phone I can control synchronization for events / birthdays / Contacts ..., however for live account there are only "Calendar" and "Task" options.
Everything is categorized under "Calendar" if it's on I see everything, otherwise nothing.
(in web access, or MS Outlook on pc I can hide birthdays and holidays correctly).
I've searched the web for a solution, however the advice for similar situations was always to go to settings and hide holidays, which option I don't have.
