Outlook.com Calendar birthdays sync issue

I'm having the same issues as the previous users have reported. I must add that some of the names that do appear in my birthday calendar do not use the names I wrote in my contacts list. E.g., my dad's real name from Facebook shows in the calendar instead of "Dad".

Hello fellow MS customers who suffer the same problem!

I followed this thread and related ones dealing with the same issue in both this English and the German support forum for a while now.

I understand that the problem of birthday entries that do not appear or suddenly disappear from both the outlook.com calender and the windows phone 8.1 calender is known since several months.

However, as m@rk summarized concisely in his post from Sept. 9th, this issue has not been solved since then at all.

This is a severe problem and not acceptable for us costumers. If Microsoft seriously wants to increase windows phone's market share above 5% this problem has to be fixed as soon as possible.

Regards,

Steffen
