I keep my domain on GoDaddy, and just would like to host a few email addresses on Zoho.

These are the settings I use to set up Imap in Outlook (it's in German, but it's pretty clear):

I chose SSL 993 and 465 for incoming and outgoing, and applied all other recommendations. However, everytime I try to save the settings I get this message:

It keeps on popping up a couple of times, until I get an error message that the set up is not working.

What's wrong here?

Thanks a lot for your help,

Michaela
