If I delete a user or users, can I assign their storage space to other users or administrators?

How can I create a user with a Proton Mail address or add Proton Mail addresses to users’ accounts?

Unfortunately, it’s not possible to create users with Proton Mail addresses, and you cannot add Proton Mail addresses to existing accounts. We’re planning to develop this option in the future.

It says I cannot enable multi-user support even though I am already subscribed to a Proton for Business plan.

Proton for Business plans come with only one user by default. If you want to enable multi-user support, you’ll need to add extra users to your plan.

To add users to your plan:

1. Log in to your Proton Account on a computer at account.proton.me and go to Settings → All settings → Dashboard → Your plan → Customize plan.

2. Go to Customize your plan → Number of users and add users to your account using the + icon (or remove them using the – icon).

Can I create a user with the exact custom domain email address I’m already using with my primary admin account?

It is possible to create a user with an email address you’re already using.

For example, suppose your primary account is harry@protonmail.com and you send and receive mail personally using a custom domain address harry@protonuser.me.

To create a user with harry@protonuser.me without deleting all your old emails:

1. Log in to your administrator (admin) Proton Account on a computer at account.proton.me and go to Settings → All settings → Organization → Users and addresses.

2. Find your primary admin user with the address you want to re-assign to a new user and click Edit.

3. Click the dropdown menu next to the address you want to re-assign and click Disable.

You’ll no longer be able to send or receive emails from this address, but your old emails will still be available in your primary mailbox (i.e., harry@protonmail.com).

4. In the same Users and addresses tab, click on Add user and create the email address again for your new user.
