I am trying to build birthday and anniversary webpart in office 365. The issue is our local ad users are synced but the birthday and hire-date are not synced in office 365.
I was checking the issue and found that we were using Azure AD Connect and that is not supporting these columns. So I have created 2 custom attribute (birthdate & hiredate) in Azure directory. Then using directory extension attribute sync, I am mapping local ad column in azure ad.
Now I am stuck here. I don't know how can I map these custom attribute with Office 365 columns. Can anyone provide any link how can I do these?
