Note: The new web mail client supports Internet Explorer 8 or newer, Chrome, and FireFox.
If you are not seeing your email in Internet Explorer 8 or above, click Tools and make sure Compatibility View is not checked.
If you are setting up a new Office 10 Outlook to get mail, give us a call. Office 10 apparently can set up your email account as an Imap account and Pop is much better unless you are comfortable with Imap.
On a side note, if you want to empty a webmail directory select it on the left, click Action, click Manage Selected Folder, click Empty and you can empty it all at once.
