You have a number of different options for accessing your e-mails using your smartphone with mailbox.org:

Option 1:

Simply use a web browser to log in to your mailbox.org Office. This allows you to access all mailbox.org Office functions. Our mailbox.org Office recognizes when it is accessed by a mobile end device and adjusts the websites to be displayed on your device.

Option 2:

Use your own e-mail client. There are many different e-mail clients available for smartphones with Android. We recommend K-9 Mail. This enables you to use your GPG key on your mobile end device using the OpenKeychain app. This way, you can encrypt and decrypt your e-mails even when you are on-the-go. You may install both apps from Google Play store or F-droid Store.

Setting up your mailbox

Please keep in mind that the e-mails stored on your smartphone are not encrypted as standard. If you want to be on the safe side, we recommend encrypting your e-mails on your mobile device. For information on encrypting your e-mails, see our instructions.
