In outlook.com, we are trying to get outlook.com to access a POP mail account.

In Settings: More email settings: Your email Accounts, we have added a Sending and Receiving POP Email Account.  We provided the Incoming and Outgoing server info, server address, username and password.  We saved these details. 

This allowed us to see our new mails on the mailserver as expected.  However, any mail that arrives subsequently isn’t visible, requiring us to go back into ‘Edit your account’ page where the mailserver password needs to be entered again as it appears to have changed.  When the correct password is entered again new emails become visible, but any subsequent emails require the process to be repeated.

Any suggestions?
