It's strongly recommended to regularly back up your address book. To do so, follow these steps:
- Go to Recipients (address book) in the left menu
- Next, click on the Export all Recipients button in the top menu
- Finally, click on Export to CSV. If you have a large address book, this can take a while.
- This will generate a CSV file. It will normally automatically be saved in your Downloads folder. Please keep this file somewhere safe, as we will need it if we ever have to restore your address book for any reason.
