[ALERT] Invalid credentials(Failure)." - Unable to set up IMAP on Outlook MAC

[ALERT] Invalid credentials(Failure)." - Unable to set up IMAP on Outlook MAC

I am trying to set up access via Outlook on MAP so I can view my emails and I have tried using POP and IMAP and I get the same error each time.

The details log in fine on the Zoho website but I am unable to access emails via Outlook or via Mail client on MAC. I have searched the forum for this alert message and am yet to find a solution. I sent an email to Zoho yesterday and still no response. 

Can anyone lead me to an answer or help. 

I am using IMAP - 
  • Incoming mail server for organization accounts - imappro.zoho.com
  • smtp.zoho.com
