Can't add new user for domain

Can't add new user for domain

Hi,

I am the super user for the domain " forkylninghosbarn.se "

I tried to add new users to the domain, but I got error message

"You do not have permissions to create this account in Zoho Mail. Reach us at support-as@zohocorp.com for further assistance."

I've already subscribed to two mail lite accounts.

Can you check it up?

Thanks
