Invite External People to Event in Zoho Desk

Invite External People to Event in Zoho Desk

Hello,

Can I add external people to an event I create in activities in the Zoho Desk?

I can see that I have the option to add Contact Name under my event but when I create my event the Contact Name I enter (that has an email connected to him) doesn't receive the event to his calendar.

So I wanted to know if this option is available or dos the event is for internal use in Zoho Desk only?

Best regards,

Maxim
