From EmailAdept: Email Recovery for Thunderbird allows recovering messages that were wiped from the Trash folder or deleted with Shift+Del. Even better, this software works where other programs fail, enabling you to recover emails after Thunderbird has compacted folders! Email Recovery can also retrieve correspondence lost due to hard drive crashing or being formatted, a particularly malicious virus infecting the system, power going off in the middle of a session, or any other reason. A truly indispensable undelete tool, Email Recovery is not only powerful but also convenient. While it allows retrieving all your deleted email correspondence, you can also choose to recover only select messages. Thanks to the built-in flexible filter you can find an important email or a message of sentimental value with a few mouse clicks, preview it, recover and rename it to make sure it will be easy to find. With its advanced recovery capabilities, Email Recovery is the best choice if you don't always remember to regularly back up your data or just want to save time while enjoying protection against Thunderbird email data loss.
