Cleaning up Email Addresses in Outlook

From time to time I’m cleaning up email addresses in Outlook or more precisely: in the Outlook Auto Complete List. Because I know that sometimes the simplest things make us struggle most I post today a little guide on how to get rid of old or mistyped email addresses in Outlook.

As we know,  Outlook remembers every address we have typed in one of these fields: “To:“, “Cc:” or “Bcc:“.
This can be very helpful in case  we don’t remember anymore a name or an address because as we start typing, Outlook automatically suggest the entire contact.

Unfortunately, Outlook remembers old addresses as well as current ones and they do not make any difference between mistyped and correct addresses. And therefore, what was thought as a help can easily end up in a huge list of  “dead” addresses. That’s why from time to time I’m cleaning up email addresses in Outlook and delete all the mistyped or old ones. The question is…
