Error inviting new user to organization

Hello @suguru, thank you for reaching out to our team, and sorry to hear about your invitation issue.

If you have reached a maximum of 10 free users on a free space plan, organization owner would have to add valid credit card details in order to go into overages.

In order to add credit card details, please follow these steps:

  1. Organization owner needs to log into the account
  2. Click on organization name in top-left corner > Organization settings
  3. On the right side of the screen you will see Your Payment Details section
  4. Click on Enter payment details

Alternatively, you can refer to the following article: Steps: How can I update my credit card details?

Hope this information helps!
