How to Lock Email Folders in Mozilla Thunderbird
Mozilla Thunderbird email software is popular, easy to use, and free. The open source movement has allowed programs like Thunderbird to spread quickly. Like other Mozilla programs, Thunderbird provides considerable customization. However it doesn't have many of the standard features of other email software. The ability to lock email folders is a straightforward process in competing software, but this feature is not provided by default in Thunderbird. With some patience and ingenuity, it is possible to lock email folders in Thunderbird so no one else may access them.
