First, there seems to be several names for this utility: for the record, ThunderTray, TB-Tray and Thunderbird-Tray are all denomination of the same Windows utility developed to minimize Thunderbird to the Windows system tray, start Thunderbird minimized, and more.
Alternatively, there is a Thunderbird extension called Minimize To Tray, also for Windows, which allows you to minimize Thunderbird to the system tray, as well as Firefox and the Mozilla Suite set of applications.

ThunderTray is a very practical utility (small computer program) for Thunderbird users on Windows. ThunderTray allows you to minimize Thunderbird to the tray area (near the clock) instead of the taskbar, where other minimized windows usually appear.
ThunderTray is not part of the Thunderbird package, but developed by Felix Geyer, an independent German programmer, who offers it as a free download - he accepts donations though.
Aside from its basic functionality, ThunderTray can start at the same time as Windows, run Thunderbird at the same time, etc. There are several configurable options.
To change or add functionality to ThunderTray, setup profiles, add items to its menu, start Thunderbird minimized, etc., you need to run a separate program, but it is very easy to do.
Go to the
C:\Program Files folder, locate the ThunderTray folder, and open it. Once inside, double-click the program called
TBTray-Config.exe. (Depending on your Windows settings, you may or not see the ".exe" at the end.)
Restart ThunderTray after your changes, and you're done!
