IMAP and CalDAV not working

IMAP and CalDAV not working

Good afternoon,

I cannot seem to get the IMAP en CalDAV integration working. I followed the guide on https://www.zoho.com/mail/help/outlook-mac-imap-access.html but all I get is "Unable to verify account name or password".

Imap is enabled in my account and all data (username and password) is correct.
