How to delete an incorrect email address showing in profile history

The YouTube video does not work on a Windows phone. I tried to follow the steps but the email address still shows in the auto-complete(suggest) list when I start typing the to address. The only way I was able to get rid of the address was to "hard" reset
the phone. Which was painfull in getting it set back up the way I wanted to.

 

email address blacklisted

Hi Hazem,

The first thing that needs to be done is to get rid of the malware itself. You may start troubleshooting the issue with your email and resolve it, only to find out that it will be blacklisted again since the malware still exist. We need to ask you the following
questions so we can help you with your concern:

• Are you using an Outlook.com email address or other email domain?
• Have you already tried to do a full system scan on your computer in attempt to get rid of the malware?
• Have you identified what malware infected your computer?
• What other troubleshooting steps have you done so far?

We will be waiting for your response.
