Deleted items not going to Outlook Trash

Deleted items not going to Outlook Trash

I recently set up Zoho, including IMAP through Outlook 2010.

In Outlook, when I delete an item, it does not go to the Trash folder in Outlook, only in my Zoho webmail.  How can I also have it go to my Outlook Trash folder?  

Also, is there anyway to have it so that my Trash folder is not emptied without my knowledge or permission?

Thanks.
