# Mailbox migration

To migrate a mailbox from a previous provider to Hosterra Email, use the [mailbox synchronization feature](https://hosterra.help/books/mail-hosting/page/mailboxes-synchronization "Mailboxes synchronization").

Once you've entered the standard parameters (target and source mailboxes, server and port of your previous provider), run a first simulated synchronization (penultimate checkbox in the window). If the simulation was successful, you can activate your task and save it.

<p class="callout info">The minimum synchronization frequency is 20 minutes. You must therefore wait until this time has elapsed for the first synchronizations to take place.</p>
