I have a bunch of contacts that are not really contacts showing in the autocomplete lists. The are not people I have sent mail to before but have sent me email. This is confusing me, and usually I can type “TRA” and get to my customer named Tracy very quickly. Instead, sometimes other entries are added to this list even though I have never added them as contacts. This is not to be confused with the privacy/whitelist issue reported elsewhere, mine is blank, or the setting that adds all emailed people as contacts, mine is off.
When The recipient is added as a recip in the email, if I right click on it , it is a contact. If I open the contact I see it is myaccount/Contacts/Recipient Cache/ . Is there any way to stop this?
