I have M-10 system it was slowing down so I purchased an exterior HD and started transferring thing to the F Drive low and behold my system is tell me I have lost my outlook profile.pst file. I don't know where it is I've tried you tube google but it's too confusing for an old geezer. I'm using Yahoo for email and my iPhone, if one of you young wipper snappers know how to make it easy I'll give it a shot. Thanks PS. Not sure I'm using the FR system correctly.
