Outlook.com Calendar birthdays sync issue

Microsoft is not taking this seriously, so I suggest that everyone who hasn't done so already:

• refers an Answer Tech to this thread on http://support.microsoft.com/ContactUs/TechnicalSupport (Outlook.com)
• reports the problem on https://status.live.com/report?productid=cal (Something else)
• clicks on 'Me Too' under 'Had this question' next to the original post

Any other routes? :)

I just permitted to post a corresponding comment on "Blogging Windows", where Windows 10 gets big hype and attention preliminary, encouraging everyone here to follow:

Thanks! The last reply from Microsoft was on September 27; they are turning a blind eye...

just ask on twitter... #BirthdayRoulette @MicrosoftHelps

We'll ser how this turns out. But I thing we'll see us next year here too. So merry xmas and a happy new year, see you in 2015

Escalate this problem (I'm talking about being ignored) one step further.

Here is the link to the feedback form for Outlook:

Tell Microsoft that we are not satisfied. 

Be sure to reference this post in your comments so that MS sees that we are all talking about the same issue

I have been experiencing this very same problem since months and no solution is in sight:

The Birthdays Calendar service is completely unreliable and Microsoft's silence on it is such a shame!

I cross-linked the two threads and encourage everyone to express negative feedback on http://go.microsoft.com/fwlink/?LinkID=255155 referencing this thread in the comments:

It does make one wonder what Microsoft's agenda is - do they want us all to purchase Outlook or some other expensive Microsoft software??  Perhaps we should all just ditch our current emails and go to another provider - that might help Microsoft to sit up and pay attention, but of course then it will be too late, we will all have gone.

Just had the same issue here, on two separate accounts:

1. built out a list of contacts in People and added Birthdays (using website People via outlook.com)
2. Added bespoke Birthdays to the website Calendar (which generated new contacts)
3. Calendar worked fine
4. Exported contacts list
5. Imported contacts to second account
6. Calendar self populated with Birthdays
7. Sync'd both with Surface Pro 3 Calendar & People app
8. All fine for 2 days
9. This morning went to add new event on Calendar app on Surface
10. All Calendar resync'd and removed all birthday events automatically
11. Checked 2nd account and same happened, all Birthdays removed.
12. Checking all contacts in the website People and their Birthdays all exist
13. Can't get them to appear on the Calendar automatically anymore
14. Not going to manually add them again.
15. Normal events (i.e. meetings) still exist, so I could manually add everything as a meeting with a Birthday charm.

Note - also noticed that the People app in win 8 (on Surface) doesn't show Birthdays and you can't add them here, assume the birthday data still exists - just want to confirm in case its a sync issue between device and web client.

Cheers
