Hello im new here and i have a very important issue.

A third party company uses one of my emails to send invoices to our customers.

My problem is that cannot connect to zoho mail server.

my imap settings are corrent

imappro.zoho.eu 993

smtppto.zoho.eu 465

i can connect to outlook with these settings but the third party company connection failed.

I tried to get a new pass for third party apps from accounts/security/password but they dont accept it ....

So what am i doing wrong.
