Friend of mine has needed to close his 2 yahoo accounts. So, I delete them in the "contacts" app area where I also have his (and everyones) u.s. mail addresses, phone numbers, etc... When I type in the 1st letter of his name the two email addresses still pop up to select! SO, I deleted his entire contact in the "contact" app. to see if that would do it. NO email addresses STILL showing up!
Anyone know how to delete an email address so it won't keep coming back up?
Deleted them out of Outlook Express so when it syncs I was hoping that would do the trick. Wrong.................

I am having the same issue, non contact email addresses continue to pop up when I type in the first letter.
Seems like a privacy issue as well.
Can anyone help me delete non contacts from mail?
Thanks!

I was beginning to think it was just me! Hopefully some resolution to
this with the OS update later this year...

Greetings,

Alas, I do not have an answer. I am experiencing the same challenge and I am running the most recent version of the OS (4.2.1). Further I have tried every trick I can think of in Contacts to delete the rogue email address or at least disable the association to no avail. Earlier today I was in an Apple Store and presented the problem to 2 different techs. Neither had a fix.

Wonderful. Of course it can't be as simple as "delete".

It seems to be responsive to e-mail address that are used a lot. Can you just select the right one several times as a trial and then the last used might show up first and the others eventually disappear. I’m new so I may be wrong, but it seems worth a try.

Have you tried deleting address' from your host computer?

You haven't said if your email account is on a server accessible from a browser like gmail or from a private provider.

Both.

I am using the Outlook type of mail. I never put contacts in my iPAD, they all come from my Outlook server. So I assume in your case , you should find a way to delete the source on your server.

The same thing just happened to me. Entered a typo, and now it's stored in Auto fill, yet not in contacts ( comes up under a recently used name though.)
There are lots of postings on this on other sights, but no answers, ( seems common on iPhone also) we need a way to clear "recent contacts" like on a real OS x machine. I've tried every way I could to trick it, even adding it to a real contact and deleting it- no luck
Any one figured this out?
