birthday dates move forward one day when entered in outlook.com but synced to mobile (British summer time)

I have worked out that if I correct the birthday dates and anniversary dates either on Outlook.com, Outlook 2010(with outlook connector) or Live mail the following happens.

When synced to my HTC Titan the anniversary dates remain correct, but all of the birthday dates in the "birthday field" on the phone that fall during British summer time (GMT+1)between the 25th of march and 28th of October move forward 1 day? However the birthday dates that are added to the "birthday calendar" remain correct? .

This problem does not affect dates in the Anniversay field only the birthdays!

If I correct the birthday field on  my titan for any of the dates that have moved forward one day then when I check back to Outlook.com, Outlook 2010 or Live mail the birthday has moved back one day from the original date!

I do not believe it is a fault with the Titan software, it appears to be with the server setting for birthdays that fall between the daylight saving times in the server.

If I add a test contact to outlook.com with a birthday and anniversary of 24th March 2001 then both dates sync to titan with correct dates, but if I change both dates in outlook.com to the 25/03/2001 then the birthday field on the phone changes to 26/03/2001 but the anniversary field stays at the 24/03/2001. This remains true for every date up till 28/10/2001 when both times become the same again with no offset.

I have checked every time zone and location setting in Outlook.com, PC and my titan and they are all United Kingdom, GMT London etc.

EDIT, Things get worse!

I have just installed Office 365 on my laptop and if i add a birth dat of 09/07/1970 to one of my contacts using the drop down calendar as soon as I save the change Outlook 2013 updates the date to 08/0701970? Outlook 2013 actually takes a day off the correct date which is then reflected in Outlook.com, Live mail etc.

This has got to be a problem with the database on the server!

    Is there any update on this?  It seems to be a fault with the way that dates are managed when you add someone's birthday details to their contact details.  If I create a separate calendar for holding birthdays as normal calendar events, that doesn't suffer the from the problem.

    Hi Michelle,

    I'm seeing the same problem but not consistently.  On some iDevices (iPad, iPhone) the Birthday entries are shown as being 1 day wrong, on the Outlook client some show correctly.

    Is there anyone out there (Microsoft???) who has a fix for this?  Very frustrating.

    Just an guess - looks like in my case (iPhone 6, IOS 10, Live.com account) shift of dates happened last March, 2017 when there was Daylight saving time change.

    So, may be there is something wrong in processing of this particular time change. Like, date is stored with time 0:00 midnight and after the switch to summer/winter time it is 01:00 of next day or 23:00 of previous?

    I still have the bug with Outlook 2016 and the outlook.com account. Imported all contacts from Google with the correct date. In outlook 2016 it was correct too but it wasn't at outlook.com and I didn't even saw the contacts in the birthday calendar before i corrected them manually...
