Very nice tool Rated 5 out of 5 stars

This is just what I needed - however, I was not able to export attachments in the HTML format or if it does they cannot be viewed. However, it does the job nicely in the EML format but then you need a EML viewer. Otherwise this is a GREAT tool and fast and accurate.

Not signed Rated 1 out of 5 stars

Looks like a good program, but my FF 45.2 will not allow me to install it because it "has not been signed". Please digitally sign this program so FF will allow us to install it! Thank you! :)

Easy to use, save a lot of time Rated 5 out of 5 stars

I have to export many emails of a conversation, means I have to mix receive and sent mails and bring them into the correct order.
Very easy with this tool, thanks so much, saved me a lot of time!

ImportExportTools Rated 5 out of 5 stars

EXCELLENT PAOLO! Mozilla NEEDS to get this into Thunderbird; I popped a gut trying to import eml's with their Import option under Tools = worthless, but yours was spot on.
However, this naturally begs the question of why you can't, won't or are unable to coordinate this with them?
If we get an answer we can believe [old timer], how about a donation coming your way via 12allen and TYVM [have donated to Mozilla more than once……good people].

Excellent Rated 5 out of 5 stars

Excellent Add-on Rated 5 out of 5 stars

ImportExportTools allowed me to re-import messages that had been saved off by accident. It didn't take to long to figure out how to do it or to re-import over 27 years worth of email.

Thanks for this great tool!

awesome Rated 5 out of 5 stars

very good

NOT WORKING Rated 1 out of 5 stars

Installed "ImportExportTools" extension as instructed, but the "Import mbox file" option is grey i.e. not usable under menu "Tools/ImportExportTools".
Can anyone please tell me any other alternative to import mbox file? Thank you very much!

As it's written above,

"Note: if you want to import messages or MBOX files, you must first select a valid folder as a target, otherwise the import options are disabled"

Select "Local Folders" and the option will be active

No longer works Rated 1 out of 5 stars

Importing messages/directories is now greyed out. Uninstalled

Hopless Rated 1 out of 5 stars

Whats the point in this programe?? I backup every night yet just now I tried to restore my emails and I get the mess "NO EMAILS IMPORTED" now thanks to my stupidity depending on this programme I've lost my deleted emails after backing them up ?? Wtf

You haven't lost anything, backup files are in MBOX format, so you must use the option to import MBOX files.

Brilliant! Rated 5 out of 5 stars

Saved me a divorce after I deleted my wife's emails when I was trying to sort out a Thunderbird problem. Thanks for a great piece of software.

Thx A lot - Great plugin ! Rated 5 out of 5 stars

Thanks for your great Job ! You give me a chance to keep my job and escape from the anger of my CEO 

I encounter an issue with a massive import of .eml files, from a 40GB export .pst file .
No error message, but the import seems to crash after few directories creation.
Is there a limitation or recommendation of size for mass import ?

Can't figure it out Rated 1 out of 5 stars

I have an 800MB archive (one folder containing many) I had simply dragged out of the TB Email folder last year. Thousands of Emails properly sorted. I wanted to add new Emails to it but dragging the folder back (it would be so simple!) doesn't work (TB doesn't see it - thanks Mozilla for that!). Either I get tons of new folders with meaningless names created, or I get folders that are empty when I try importing a sub-folder. Needs better documentation. I'm not willing to risk my Email archive getting corrupted by this add-on.

Works Great Rated 4 out of 5 stars

-Works great, saves hours of work.
-Easy to understand.
-Many options.
Will not import messages from a single mbox file (forwarded from an account, to the same account.) e.g. sent to

It works, but can be confusing - there is no progress bar... Rated 4 out of 5 stars

1. When exporting a folder, be sure to right click on the folder itself inside TB. Otherwise, you are exporting whichever folder you happen to have highlighted when you start -- this isn't made clear anywhere.
2. It is slow, and no progress bar. Just go to the exported file location and watch the file size change. If changing, then working...

Export All Email Addresses Rated 5 out of 5 stars

love this tool, thanks :)

is there a way to export all email addresses, even those that are not in my address book?

Simples e funcional Rated 5 out of 5 stars

Exporta minhas menssagens de maneira simples e rápida. Posso salvá-las em uma mídia externa, agora.

Export/Import Profile option is awesome!! Rated 5 out of 5 stars

Used the ImportExportTools EXPORT PROFILE option before wiping my computer and performing a fresh install of Windows 10.
After installing Thunderbird and adding ImportExportTools again I used the IMPORT PROFILE option and it worked perfectly. (Mailboxes, folders, addresses, THE LOT! )

TOP TIP: During the import process, select the folder then just type whatever you like in the box 'Name of the profile to import'.

no pst files Rated 1 out of 5 stars

Import no .pst files and those files are the most important oultlook files.

This review is for a previous version of the add-on (3.2.4).
