Outgoing mail hangs on Outlook

For some reason my outgoing mail has started hanging and moving to the Outbox and just staying there. The problem started about a week ago for no apparent reason (have been using the mail successfully for some time now w/o glitches).

I am using Office 2010 and Windows RT mail - both programs hang.

I have deleted and then added my .me account onto the RT and still hangs.

I have confirmed the settings:

Incoming:

• imap.mail.me.com
• SSL - yes
• Port 993
• User name user@me.com
• Password - ditto

Outgoing:

• Server: smtp.mail.me.com
• SSL - yes
• Authentication - yes
• User: user@me.com
• Password - ditto

Could somebody please help?

Thanks!
