"Invalid Credentials(Failure)" when configuring IMAP (Outlook)

"Invalid Credentials(Failure)" when configuring IMAP (Outlook)

Getting the below response when attempting to configure Zoho mail in Outlook 2016:



Notes (what I've done so far):
  1. Zoho mail on web client is working with no issues.
  2. Though I was certain the username & PW were correct (was using same credentials on web client as I was attempting to utilize in Outlook 2016), just in case, I went ahead and changed my password on the web client and re-attempted Outlook configuration; same error response.
  3. IMAP for my email account was enabled on the web client (and POP was disabled; am I correct to disable POP, or does it even matter?).
  4. Followed all of the configuration instructions from here: https://www.zoho.com/mail/help/outlook-imap-access.html. Am 100% certain that all of the details were correct, including 
    1. Incoming/outgoing servers
    2. Logon information
    3. More settings: General, Outgoing Server, and Advanced tabs (and on Advanced tab, ensured that Incoming and Outgoing servers were correctly input and SSL was chosen from drop-downs.
Appreciate your help!

Best regards,
Peter
