Rated 5 out of 5 stars

This addon has helped me tremendously.

The old importexporttools addon has stopped working, this updated version allowed me to restore my system after a computer failure required new hardware and a system reinstall. That coincided with a new thunderbird release and the loss of access to all my email backups....

After (at first panicking) then installing this updated addon I was able to restore all old backup emails from my stored weekly schedule via the mbox files on my secondary hard drive.

My new system hard drive with the new thunderbird and importexporttools NG had no problems whatsoever reading the mbox file and restoring my emails in their entirety, attachments and all.

I was honstly expecting all kinds of problems but it really was a warm summer breeze getting everything back to how it was before disaster struck. A huge relief.

Thank you.

This review is for a previous version of the add-on (4.0.4).
