I have finally managed to set up the Mail app on Windows 8, to send/receive emails from my Outlook.com account, and my two other IMAP accounts.

However, the Live tile does not work (just shows an envelope), and the system does not check for new emails automatically (I have to open the application and click the Sync button to get new email messages).

I have tried changing the 'Download New email' settings under each account (have tried the 'As they arrive' and 'Every 15 minute' options), but still no luck.

I have updated the Mail app (now have the version which includes email grouping), and it still doesn't work.

Any help is much appreciated.
