Create your hosted mailbox

Provisioning happens during signup.

This registration flow creates the app account and provisions the hosted mailbox behind it, so the first login lands in a real inbox instead of an empty shell.

Mailbox creation

Signup provisions the hosted account and sync metadata needed to send mail.

Password

Use your mailbox password. It is reused for the immediate post-signup login.

Hosted domain

Addresses must belong to the hosted domain configured for this deployment.
