Outlook 2013 finding phantom profiles that do not appear in the Mail Control Panel applet

Outlook 2013 running on Windows 8, straight POP client configuration. Client calls me today to say her email is not working. I remoted in to find that Outlook was pointed to the wrong location, reset the data file path to the correct one, Outlook starts, the expected email store is there, but getting data file error: Task 'work - Sending' reported error (0x8004010F) : 'Outlook data file cannot be accessed.'

I create a new profile, point to the old data file, same error. I create a new profile point to a new data file, Outlook still opens the old data file! So, I delete ALL profiles, Outlook starts with a profile that it finds, who knows where! I set profiles to always prompt, with NO profiles in the Control Panel Mail app showing at all, they are all deleted, but when I start Outlook there are two old profiles in the prompt list! Where are they coming from??? No matter what I do, Outlook finds one of these "phantom" profiles, starts up, but does not work of course, with the error as above: Task 'work - Sending' reported error (0x8004010F) : 'Outlook data file cannot be accessed.' Help!

On further investigation, I found that BOTH Office 2010 and Office 365 (Office 2013) were installed. I removed Office 2010, did a full repair on Office 2013, and lo and behold, the "phantom" profiles appeared in the Control Panel Mail applet. I deleted them, created a new one, and we are working again.
