How to do backups

E-mail Print PDF
You are responsible for making backups of your entire mailbox data on a regular basis. Here we'll show you how to do frequent backups of your online data:
  • Microsoft publishes a very nice tool for Outlook that makes backup of your data easy. You can download it here directly from Microsoft:
    • After installing it you find a new Menu option in Outlook
    • Click on File --> Backup Copy and follow the backup steps.
  • You can do it manually as well:
  • Open Outlook, click File --> Import/Export --> Continue.
    Choose Export to a file --> Personal Folder File (.pst) --> Continue.
    Choose the folder you wish to export (if in doubt just choose the topmost folder) and click on it. "Include subfolders" should be checked.
    Choose a location to store the file (e.g. "Desktop") --> Complete.
    Click "OK".
    Wait for the export to go through without any errors; this may take some time depending on the size of your Outlook data files. You should save the export file in a secure location.
  • If you are using the Desktop Application (Windows, Mac, Linux, see Downloads section), then backups are very easy:
    • Click on Preferences (Options) --> Import/Export
    • In the "Export" section, activate "All Folders", check the box "Advanced Settings"
    • Choose what to export (Mail, Contacts, Calendars, ...)
    • Click on the "Export" button.
  • For users of other applications we have an easy backup solution as well:
    • Log in to interWaysMAIL  Webmail (
    • Click on "Preferences" (Options)
    • Click on Calendar
    • Kalender Einstellungen Screenshot
    • Click on "Export as .ICS File" in the "Import/Export" section
    • Save the exported file on your computer or external backup media
    • Kalender Export Screenshot
    • Click on Address Boook
    • Choose a file format (Standard: Outlook 2003 csv) in the "Import/Export" section.
    • Click on "Export"
    • Kontakte Export Screenshot
    • Save the exported file on your computer or external backup media
    • For Emails: Use an application like Thunderbird or others for POP3 download of your mails to your computer (see: Server Settings)
    • Frequently download your mails to your computer using this application

Please make your backups frequently (best: daily) and thoroughly.

The backup files created following these steps are standards-conforming and can be used with most applications and providers.
