@kncowans: Have you tried checking the affected contacts via the desktop version of Outlook to see if the format of the birthday information matches the contacts that are syncing successfully? On the Calendar app itself, try tapping the 3 lines in the top left > Manage contacts > Microsoft account, and check your options here to see if Contact Birthdays is selectable. You can also tap the 3 lines in the top left via the Calendar landing page, then tap the drop down arrow new to your Microsoft account to explore your available options.
