This is my first post so excuse my if I have done it all wrong.
We have had some email abuse so I have changed my email address and deleted all my contacts from my ipad. Now if I go to write a new email if for example the email address starts with rog as soon as I type in r it brings up some of my old email addresses that I have deleted from contacts plus it bring up `message email reply` with a lot of letters and number next to it. I am worrid this relate to the person that sends the abusive emails. How can I get rid of this?
Unfortunately, you've run into one of Apple's "features.
And, I'm sorry but you can't delete those addresses. That's a "helpful" feature by Apple that, well, isn't. At the present time (and since the start of the iPad) there is no way to remove those addresses from a stock iPad. The best you can hope for is for them to get pushed further down the recommendations list because you don't use them.
We keep hoping for a change but so far, no luck. Again, sorry.
