If you have a Proton for Business(new window) plan or a legacy Visionary plan with a custom domain(new window), you can create an organization(new window) and add users to it.
Learn how to add users to an organization(new window)
This article explains how to remove users from an organization. To do this, you must have administrator(new window) rights.
How to remove members and secondary administrators from an organization
1. Log in to your Proton Account at account.proton.me(new window) and click Settings → Go to settings → Organization → Users and addresses.
2. Click the arrow next to the Edit button in the Action column for the member you wish to remove and select Delete from the dropdown menu.
3. You’ll be asked to confirm the name of the user you wish to delete. This is a security feature to help ensure users are not deleted by accident. Enter this and click Delete.
How to remove the primary administrator from an organization
Warning: Removing the primary administrator (admin) from an organization can have serious and unrepairable consequences.
For example, if an issue arises with the DNS settings for your organization’s custom domain and the required DNS records stop propagating, all custom domain addresses will become disabled. If this happens, none of your organization’s users will be able to log in and re-authenticate the domain.
If no such issues arise, then all users can continue to access their organization emails as usual.
The instructions for removing a primary admin are identical to those for removing a member or secondary admin (see above). Only another admin can delete a primary admin account.
