When I type in the first letter of my contact’s email address in the “To”, “Cc” or “Bcc” address bar, I no longer get a drop down menu of all my contacts starting with that letter. They were all there on Friday but have simply vanished over the weekend somehow. Can anybody tell me how I can get them back as I do not save every email address I reply to or send to, to my Contacts list and now I am missing a few important email addresses.
