How to get started
The TbSync Add-On is listed in the Mozilla Add-On repository. To install the official version of TbSync open Mozilla Thunderbird, go to the Add-On page and search for "TbSync". Install TbSync from the results list.
The official version might not be the latest release. To install the latest release, download the "XPI" file from the latest Github release page, open Mozilla Thunderbird, go to the Add-On page, click on the gear icon located in the upper right corner, select "Install from file ..." and select the downloaded XPI file.
After the Add-On has been installed successfully, the current status of the Add-On is shown in the lower right corner of the main Thunderbird window. A single click on that status field will open the TbSync account manager.
There is not much to see until some accounts have been defined. Open the account actions menu in the lower left corner to add a new account.
Choose a name to identify the ActiveSync account, enter the user name (probably an email address) and your password. Most ActiveSync servers support an automated configuration process called Autodiscover. If this is not working for your ActiveSync account then you'll have to select custom configuration and enter the server details by yourself.
A fully-configured account will look like this:
Below the server settings are a few additional settings which should be self explanatory.
To connect the account and to initialize the synchronization, click on Connect account. TbSync will then retrieve and display the list of folders available on the ActiveSync server (the configuration options will be hidden):
TbSync supports contact folders, tasks folders and calendar folders. The default folders will be synchronized automatically. To subscribe/unsubscribe a folder, double click on it.
The status of each folder will contain the name of the local synchronized item. In this example, the default calendar of the shown Outlook account has been synchronized to a Thunderbird calendar called Kalender (Outlook) and the default address book has been synchronized to a Thunderbird address book called Kontakte (Outlook). You are free to change these auto-generated names. If you delete one of these local items, they will be recreated during the next synchronization.
At the moment, TbSync does not support push sync. Changes will only be synchronized, if you click on "Synchronize this account". However, you can enable AutoSync by settings up a sync interval in minutes. TbSync will then synchronize your account automatically.
