I would like to create shared address book for Thunderbird and Outlook.
Partly, I did this using Radicals as a CardDav server and addons to Thunderbird (tbSync) and Outlook (CalDav Synchronizer).
But in this case the groups does not work. (The group created in Thunderbird is only valid for other Thunderbirds. Similarly: The group created in Outlook is only valid for another Outlook.
Can anyone tell me what should I do (which soft to use) to make it work?
