iCloud added anniversary dates to all contacts.

I'm on iCloud & Outlook 2007 so my suggestion is an uncertain one - but here goes.........

In Outlook: suggestion one:-

Go contacts and select view as Phone List.

Select Customize View, then Fields, then All Contact Fields, and add Anniversary.

Thus Anniversary is now a column.

You can delete that field's data individually. I don't know of a way to delete all the column in this view.

Laborious yes with 1500 contacts, but do a bit at a time?

Suggestion two is to export the contacts as a CSV, edit that file in Excel, and delete the data there. Of course bulk delete is possible here. Save. Then re-import the resultant CSV.

At all steps, backup backup etc etc :-) Cheers @PedroStephano

I have exactly the same problem.

Thanks for the suggestion PedroStephano, but the problem is not in Outlook contacts - they show anniversary as "none". The problem is in the Apple devices such as iPhone, where all the contacts that were synched from Outlook to iPhone (via iTunes) are showing anniversary date of 01/Jan/4051.

Please help!

I just posted a question about the same problem, iphone, icloud, outlook sync, 2000 contacts, anniversary jan 01 4501, dint notice this discussion, I hope some one can find a solution.

thank you

Any updates on this one chaps?

If youre on outlook, I'd suggest using that as your field editor. It's possible to show the anniversary fields column in "Phone" view mode, and then edit and delete each field pic.twitter.com/YtzRhys78a Slow to do 2000, but do ten at a time and you''ll get through them eventually.

Thanks PedroStephano, but as I mentioned before the silly dates do not show up in the Outlook contacts. They only show up in the iPhone.

Then refresh icloud through outlook

I would also like to know how to DELETE the "anniversary date" without having to "manually" access and EDIT each one.

This happened to me as well. Same date. Still no answers?

Unfortunately, the problem does originate with Microsoft. They use January 1, 4501 to represent 'None' in the date field. Outlook interprets it as a blank field. Apple does not. Doesn't get us any closer to an easy solution, but at least it tells us where it started. Little bit of background at:

SSo the long and short of it is no solution. Don't bother deleting them on iPhone- they just come back. I guess we live with it. Surprised with all the smart ppl at Apple a solution can't be found. Seems like an algorithm to deal with shouldn't be that hard.

HI to all. After reading a lot of blogs and pages you finally get something. its very simple but we aren't aware of some facts

when we sync our contacts with iCloud from outlook for the first time it automatically inserts a anniversary field in your contacts. And in outlook it might look blank but in iCloud and on the iPhone it will come up as 4045 or whatever. so our job is to get them all to "none" in the anniversary feild. So when you read about how to move them all into the group in list view where there's the group of contacts that have a none by anniversary and it will change all your contacts to anniversary none!!! But one little tip no one told us is that in order to change it into a "none" you first have to give and create a anniversary date, doesn't matter which date. Only then can you really get it to become none. And like this you first change them all to with a date and then back to with out a date and then you will no longer see anniversary in you contacts. And you can change them all in one shot.

THanks. I hope this helps someone.
