For the **bidirectional synchronization** option **with Mailbox.org** to avoid conflicts in bookings, click on **"Add"**, choose the Mailbox.org calendars with which you want to perform the bidirectional synchronization to avoid conflicts in the bookings made from the TuCalendi calendar and click on **"Apply"**.

When you have checked the options you want, click **"Save"**. The synchronization between the TuCalendi event and the Mailbox.org calendars you have selected will be done.

From now on, when your customers book the event with you from your TuCalendi calendar, it will be **added to the Mailbox.org calendar** of your choice. If you have added events in Mailbox.org, those **times will be blocked** in TuCalendi and will not be bookable.
