Our mailbox.org Office interface provides you with a number of different options for synchronizing your calendars, address book, e-mails, and files with your different devices. This overview is intended to help you select the right option for you. Here we list the synchronization methods for the different systems (though with some hard work, you may be able to find more… :-))

We recommend

using these data synchronization methods if possible:

  • E-mail: Using IMAP and SMTP with your e-mail program
  • Calendar and tasks: Using CalDAV with your calendar program
  • Address book: Using CardDAV with your address book program
  • Files: Using the Drive Client or the web interface

We also offer ActiveSync, which is easy to set up, but often causes problems. Some functions many be limited or unavailable depending on your version of mobile device. For example, sometimes multiple calendars or address books cannot be synchronized, e-mails may only be available for a limited time, or tasks may be synchronized without the specified times or repetitions. Note that ActiveSync was developed to transfer current information to mobile devices as quickly as possible. It is not designed to synchronize mailboxes with a large volume of e-mails or to keep old e-mails synchronized on a permanent basis. If you would like to keep a large amount of data or all of your data on your mobile device, use one of the recommended synchronization methods described above. Please note, that we cannot offer support for activesync problems.
