How do I import my Thunderbird address book into Posteo webmail?

The easiest way is to set up address book synchronisation and drag your contacts with the mouse from Thunderbird to your Posteo address book.

There is another way (for a large number of addresses) that functions using a special export plug-in, which you have to install for Thunderbird.

Right-click this link and choose “Save as”. Download the file, in order to install the plug-in in Thunderbird via “Extras” → “Add-ons”.

Now you are able to export the address book as a “vCard”: Go into your address book and right-click on the desired address book. Choose “Export as vcf file”. This file can then be imported into the Posteo webmail address book.
