I am not able to edit the birthday field of a contact. At least I don't see the field.
Please add this feature.

I can confirm the issue. There's no way to add or edit Birthdays via Outlook on Android. This is so inconvenient and makes me want to bring my contacts to Samsung Account.
Please, fix this!

It's not possible to delete and edit entries from birthday calendar. This functions has failure. The data does not come from "Contact". I don't want to see entries of persons I don't have a contact any more.
