Outlook.com Calendar birthdays sync issue

Unfortunately, still we're playing birthdays roulette. For this month, here's my birthdays calendar and screenshots of contacts with known birthdays, currently missing in the calendar:

I permit to summarize again:

• Birthdays disappear and sometimes re-appear in calendar by random
• All types of contacts are affected**: standalone Outlook.com contacts, linked contacts, standalone Facebook/ Skype etc. contacts**
• Manual sync of birthdays calendar doesn't resolve
• Un- and relinking contacts as well as deleting and recreating the birthdays calendarmight result in more or less complete listing of birthdays on short-term -but it doesn't solve the service bug in general**: birthdays will randomly disappear and re-appear again**

This issue is reported since months! Might get assumed that just syncing a Birthdays calendar properlyshouldn't mean rocket science for a company like Microsoft ...

@Moderators: what does it take to make you just take this issue serious, reported and confirmed repeated?Wasting our time by annoying users with senseless boilerplates again and again doesn't resolve the issue! What exactly is the state of investigation? Have you even reported this to Microsoft? Are they aware of this thread for instance?

@Microsoft - aren't yourselves using your offered services? Please realize: an inconsistent birthdays calendar service is worthless. Please analyze the birthday calendars' sync processes and finally fix the service!

Any kind of serious support is highly appreciated. We're all curious about findings and results. Since months...

Thanks.
