How to show Contacts' Birthdays on my Calendar ?

There is not an 800#, sorry. You are using Outlook on the web, correct? It might be easier to do some of this in Outlook desktop - especially deleting the contacts after exporting them.

In Outlook on the web, open the contacts folder and on the upper right is a Manage button. click it and select Export. The choose All.

To avoid duplicates, you should delete the contacts - but outlook on the web only deleted 50 at a time. If you have Outlook desktop software, you could delete all at once.

If only some of the contacts have birthdays and you don't want to spend a lot of time deleting 50 at a time, open the exported file in Excel and delete the rows that don't have a birthdate.

When you are ready to import, go back to manage and choose Image.

Did you turn the birthday calendar off at some point? If so, you need to export the contacts and import them so the birthday calendar can pick up the birthdates. Or open each contact and edit the birthdate and save.

Thank you Isra, for your reply but it is turned on.

And the Calendar is still not showing birthdays...

To be sure, do you use Outlook desktop or Outlook web? In the forum category it says that it is Outlook for pc but I would like to be sure.
