Well, my email on Outlook.com didn't last long. I wasn't happy with how the server operated within the Windows 10 Email or Outlook clients (uses a web api and not a true IMAP server). Webfaction, my hosting company for the past five or so years, also handles email but I never used it. I set it all up and moved my wife's domains over to it as well. They worked with me to upload 10GB of archive mail (since 1999) that my wife collected. I don't hang on to email that long so I didn't have a lot to move over.
All of our secondary accounts now forward to one main account on Webfaction. Its nice to actually have a real, authentic, IMAP server and not a Google imitation.
