Outlook.com Calendar birthdays sync issue

I ran into this problem as well today.  I checked the Calendar this morning and almost all my contacts' birthdays were gone (they were still there last night). The birthdays in my "Birthday calendar" are exclusively from Skype contacts (there may be some birthdays from Messenger contacts too).

I think I managed to fix the problem by deleting my "Birthday calendar" (gear icon --> "Options" --> "Birthday calendar" under "Edit your reminder and calendar settings" --> "Delete" at the very top of the page --> "Delete" in the "Delete calendar" box) and then re-creating it (little arrow next to "New" --> "Birthday", etc.).

I say I'm not sure it worked because, while it looked like everything came back, I didn't go through all my contacts individually to make sure that all their birthdays appeared on the Calendar. Also, from what people are saying in this thread it sounds like the problem might reappear without warning.

By the way, I think it's important to point out that this problem has existed at least as far back as July 2013: http://www.theevilels.de/?p=2574.

tried, doesn't work...

Hi, I was able to delete the birthday calendar as you suggested but haven't found a way to re-create it. Could you please walk me through the steps? Thanks.

We understand your concern with urgently resolving this issue with your birthday calendar and we apologize for not getting back to you sooner. However, we've checked your inquiry and determined that it's still under investigation by our Support Specialists. Rest assured that we are doing our best to fix this. We'll notify you on this thread as soon as updates about it have been provided.

Have a happy November, all together!

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 repeatedly?Wasting customers time by annoying them 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.

I have seen many posts about people having problems with getting birthdays to sync between People and Calendar.  I'm having the same problem myself.  I added all my birthdays to Calendar and they showed up fine for a couple of days, then they all disappeared.  I discovered that they are all now showing up in People, but NOT in Calendar.

I see that you are telling folks you will reply to them privately, rather than acknowledging that this is an issue and posting some kind of a fix.  

So I'm posting my message and hoping you will contact me directly.  My email is ******@nmi.org and I would be happy to provide you with screen shots of my People and Calendar which are NOT synching properly.

Thanks.
