In absolutely typical UK fashion (i.e. the corporations are contemptuous of consumers) it is hard to make a UK edition Kindle Fire HD device talk to your o2 email servers. This is despite o2 publishing all the technical details! What information the support sites omit is the remedy! From internet comments, the firm just cannot be bothered to tell you what ORDER to do things, given some quirk in the Kindle software.
First make your incoming email work (ignoring any and «all» fields to do with outgoing) email settings. That is the magic. This really means changing the word “pop3” in the suggested domain-name for the incoming email server to the word “mail”. Now make it work, before proceeding.
Later on, once the incoming email is visible as expected, go change the suggested outgoing port to 25. Do not do anything else! Do not fiddle with names, logins, addresses, passwords….
O2 know this, but don’t let on. Keep the English peasants stupid and dependent, apparently. Make money by hiding information. Now O2 can deliver “service”.
Don’t forget, peasant, that when trying to make incoming email work you may be in a world in which you may have already configured your Outlook client to be also downloading incoming emails from O2. And, you MAY WELL have set outlook settings “to delete the emails from the server” upon delivery (to outlook). You need to reconfigure outlook for your kindle – so outlook leaves the emails on the server upon receipt. That is, ensure outlook only deletes the server side copy when you delete a message using some device’s app’s delete button. This way, you will see your incoming test emails in your kindle – since no longer may outlook be having the server delete from the server (before the kindle has a chance to connect)
Oh O2! Real customer service is NOT that hard.
