Zoho does not send invitation email if meeting is created in calendar

Hello
How to overcome the problem with not sending invite letters about creating an event in the calendar?
Read https://help.zoho.com/ many requests on this topic. And not one answer. In addition to the standard answer - write to us by mail in support

The invite does not come to zoho or to other services like gmail.com, etc.
