If you delete a user, you will have unallocated storage space and VPN connections. The remaining storage and VPN connections aren’t automatically re-allocated to the other users.
If you wish to re-allocate storage space or VPN connections, you can assign this to specific users or administrators:
1. Log in at mail.protonmail.com and go to Settings → Go to Settings → Organization → Users and addresses.
2. Locate the user you would like to allocate extra storage or VPN connections to and click Edit.
3. Click on the dropdown menu next to Account storage and select the total storage you want for this user. If you’re subscribed to a VPN plan, you can also allocate extra VPN connections to this user with the VPN connections dropdown.
4. Click Submit.
