Microsoft adds new calendar options in Outlook for Android
Firstly, Outlook for Android includes a new option to respond to an event without notifying the organizer. Moreover, you can now set events on your calendar as free or busy, something that wasn't previously possible.
It's also worth noting that the new update brings a new feature that allows Outlook users to include a note when they respond to an event. Last but not least, Android users will now be able to mark events as private to keep them to themselves when their calendar is shared.
As with all Microsoft's update for Outlook, this one includes some bug fixes and performance improvements that should address some small issues and further improve the user experience.
