1. To send your e-mails via the Hotmail web page (rather than Outlook), right click on the link and select 'Copy Shortcut'. Go to the Hotmail page and start a new message. Right-click in the address bar and select 'Paste'
2. (This is based on Outlook Express but I think it's the same in Outlook). To send mail without the missing send button, go to File > Send message.
3. (Also based on Outlook Express). To recover the missing button, open a new mail (either directly or from a link). Go to View>Toolbars and click on 'Standard'.
