The most popular usecase is to synchronize a server with a local folder and use a set of other programs to change the local events and contacts. Vdirsyncer can then synchronize those changes back to the server. However, vdirsyncer is not limited to synchronizing between clients and servers. It can also be used to synchronize calendars and/or addressbooks between two servers directly. It aims to be for calendars and contacts what OfflineIMAP is for emails. Users 1 vdirsyncer Documentation, Release 0.18.1.dev82+gdb6da70 2 Users CHAPTER 1 When do I need Vdirsyncer? 1.1 Why not Dropbox + todo.txt? Projects like todo.txt criticize the complexity of modern productivity apps, and that rightfully. So they set out to create a new, super-simple, human-readable format, such that vim suffices for viewing the raw data.

Client configuration Thunderbird on Desktop computers (Windows, Mac, Linux) 1. Install CategoryManager app in Thunderbird –> Add-ons 2. Download SOGo Connector and manual install from file. Make sure to pick the correct version for Thunderbird. 3. If the SOGo Connector cannot be installed as an app, download the SOGo Connector with a right-click on the button, then install it from file in Thunderbird. 4. Open Address Book, then click File –> New –>Remote Address Book. Right click on the new address book, disable periodic sync, and enter the following URL to connect, replace “user” with your user name.: Synology DSM: https://your.domain.tld:8443/addressbooks/users/user/addressbook/ ownCloud server: https://your.domain.tld/remote.php/dav/addressbooks/users/user/default/ 5. If you have an existing remote address book, change the URL to sync existing contacts. Right click the remote address book and select Synchronize. If you don't, you must initiate the first sync from your mobile device. 6. Thunderbird will ask for the access credentials to your DAV server, enter them, and select save to Password Manager. This way, you will not need to enter the credentials repeatedly for Address Book and Calendar sync. 7. After the first manual sync, change the settings of the Address Book to Periodic sync. 1. https://github.com/jobisoft/DAV-4-TbSync/issues/59#issuecomment-459685281 Contacts on iOS 10 1.
