I use the default Samsung Mail app that comes with the Galaxy series (I prefer this over every other mobile email app for its usage of space, swipe options , appearance and many other features!) After using NFC to sync my old phone and the new one, my Outlook email opened in the Gmail app which I definitely do not want to use. Stranger though, I could not add my Outlook account in order to sync my contacts because the account was already in use. Removing the account introduced new problems – now I couldn’t add the Outlook.com account at all.
Microsoft changes its supported email clients (goodbye OE and Live Mail, hello Windows Mail or the browser). Compounding the issue are the constantly changing addresses from which your account will retrieve mail – remember, these are statically set on a mobile device or a client, not automatically redirected with DNS as when you are using the web interface.
A number of Microsoft help pages tell you to use alternate mail servers – m.hotmail.com, s.outlook.com, among others. None of the suggested addresses yielded different results.
On a hunch, I tried using “m” (which I can only assume is for “mobile”) in front of “outlook.com”.
