Thank you for the feedback. We’re working on improving the overall experience with birthday calendar and daily agenda mail to make it more personal and relevant. If you prefer not to receive your agenda in mail, you can opt out by going to Outlook.com > Settings > Calendar > Agenda mail.

Nowadays, many phones have push notifications, so, if you could create an options for disabling e-mail notifications for birthdays, it would not notify me the event from the calendar app and e-mail app simultaneously. Also it's kind of annoying to see e-mail full of reminder that I don't need. Hope you can add this feature to fix this issue soon enough. ><
