Apple Mail issues

Dear Sir or Madam,

I am trying to configure my Zoho mail account to Apple Mail.  It is not working.  It seems to need more information (perhaps a path prefix?) than is shown in your tutorial (<www.zoho.com/mail/help/apple-mac-imap.html>). 

After plugging in the info for the incoming mail server info, it simply reads "additional account information required".  When I then click next, it wants me to plug in path prefix (which I left open), port (I put 993 and use SSL), and authentication (I chose password from the dropdown menu).  This is perhaps where the problem lies?  What should I put here?

When I then click next, I again just plug in the info from your tutorial.

When I open the connection doctor in Apple Mail, it is the IMAP connection that is listed as red and failed.  It says to verify that the username and password are correct.  I have completed this process several times, and made sure that the username and password are correct.  Please help.  Thanks in advance.

Kind regards,
P
