Error while retrieving messages with Outlook.

Error while retrieving messages with Outlook.

I've got a renegade e-mail that will not download to my Outlook mail.  I logged in manually to Zoho and do not have any new messages online.  But Outlook is advising I have one.  When I click the SEND/RETRIEVE button, it advises it begins RETRIEVING 1 OF 1...  eventually, it times out and I get an error message that says:
 
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'mailpop.zoho.com', Server: 'mailpop.zoho.com', Protocol: POP3, Port: 995, Secure(SSL): Yes, Error Number: 0x800CCC0F
 
 
 
Is there a way to clear this "cache" and delete that piece of e-mail that seems to be getting hung up for some reason??  I tried deleting my Zoho POP3 account from Outlook.  Then I set it up again hoping that would somehow do the trick and it is still there. 
 
Anyone have any ideas?????     Help??
