There are two types of users:
- Non-private users (the default)
- Private users
You can only access the mailboxes of your non-private users. If you set a user as private, you cannot undo this, and the mailbox cannot be accessed by any administrators.
To access a non-private user’s mailbox:
1. Log in to your administrator Proton Account at account.proton.me(new window) and click to Settings → Go to settings → Organization → Users and addresses.
2. In the Actions column next to the user whose account you wish to access, click ∨ and select Sign in from the dropdown menu.
You will be asked to enter your login password for the admin account you are currently using.
