Worked for me! Rated 5 out of 5 stars

Be careful to apply the "message synchronization" hint!

Yes thank you, excellent! Rated 5 out of 5 stars

Yes. This is exactly what I was missing. Thank you, works perfect!

Not working in 45.2 Rated 1 out of 5 stars

In previous version it was OK. Transfered a lot of emails in minutes and you could still work with Thunderbird. Now having latest TB version it copies one mail in minute and TB got stuck. I know it is not compatible but will you one day update this plugin?

for my purpose it s just a useless add on

Can't copy account to Local Folders in TB45.1.1 Rated 1 out of 5 stars

Totally worthless waste of time. Attempt to copy account to Local Folders always generates error:
"Failed get messages from: <source account> aborting"
To author: Pull it down until you can get it working!

Has difficulties with Subfolders Rated 3 out of 5 stars

More often than not, this app will fail to copy the contents of subfolders, although it's happy to create the subfolders itself. Most of the time it can go one subfolder deep, but beyond that, it just doesn't work properly. Otherwise, works well.

Problems in TB45 Rated 4 out of 5 stars

Workaround is to disable color folders extension

Problems with TB45 Rated 3 out of 5 stars

This addon was really valuable for me until the update to TB45. Now I only get the recents folders as targets as hejwazzup22 also wrote some days ago.
It would really be great if the addon would work again. Obviously something basically has chnaged concerning folders as the colorfolder addon also quit working.

I tried to disable Color Folders addon but this did not help. The context menu only shows "Copy To - Recent -" the other entries in the menu are missing.

EDIT2: Still with 45.1.1 it does not work, same behaviour as before, no matter if Color Folders is installed or not or disabled or not.

Doesn't work anymore @ Thunderbird 45.0 Rated 2 out of 5 stars

I love this add-on, but it doesn't work anymore with version 45.0
When I press 'copy to' it only states 'recent' en no more choices... Can you please fix it?

Unbrauchbar - kopiert unvollständg Rated 1 out of 5 stars

Die fehlende Kopierfunktion für Ordner und Ordnerstrukturen durch ein Addon nachzurüsten ist sicher eine gute Idee, doch leider funktioniert dieses Addon nicht zuverlässig. Wie in anderen Bewertungen bereits geschrieben, werden nicht alle Emails eines Ordners kopiert. Ich habe in einem umfassenden Versuche viele große Orderstrukturen kopiert und fast bei jedem der ca 150 Ordern fehlen einige Emails. Es ist auch nicht nachvollziehbar welche Mails fehlen. Wenn man eine fehlende Mail gefunden hat, kann man die problemlos "händisch", also ohne das Addon, rüberkopieren.
Aufgrund dieser Unzuverlässigkeit ist das Addon leider unbrauchbar. Es wäre schön, wenn der Entwickler sich hier mal auf Fehlersuche begeben würde.

Works great! Rated 5 out of 5 stars

I used this add-on to copy mail to our new mail server as we migrated to a different host. A few bumps with folders that weren't subscribed to in the destination account, but other than that it worked perfectly! :)

Hangs, abort,s does not copy all emails Rated 1 out of 5 stars

Tried to copy gmail to local. Copies less than 1/2 of 144,000 emails. Tried copying a group of folders and each folder and sub folder is missing one or more emails. Some folders have emails copied that are corrupt. Space usage says 101% at 15 gig, on a Mac this limit should not be happening. Unreliable. DO NOT USE THIS ADDON!

Wonderful idea, but not working. Randomly 'forgets' messages to copy. Rated 1 out of 5 stars

Wonderful idea, wished it would work OK,
But unfortunately not working. Randomly 'forgets' messages to copy in a subtree.
(I could show the developer screenshots of the differences)
It's more than nothing. It does copy all the subfolders. So the structure is copied at least, then per (sub)folder I copy or move the messages and then remove the duplicates.

FAIL Rated 1 out of 5 stars

It creates folders from saved searches (virtual folders) in the destination, and then it freezes after creating the folders, without copying anything.

Copy but why not MOVE? Rated 3 out of 5 stars

I'd rather MOVE than copy the messages. If copying, you'll end up with lots of duplicate messages because the copy process never runs through but you'll have to start over several times.

Btw, this is the typical WTF-moments you unfortunately get with Copy Folders after like three hours:

v 2.1
if i select multiple folders it copies only the first one. so then i select one by one and it wont copy the subfolder content. but then again working randomly. try/testing gmail to hosteurope. win7 x64 TB 38.1

Randomly misses copying all messages. I really could use something like this if it ever works more accurately.

This is seriously S..L...O....W. And now I am reading emails in my new IMAP hotmail account and they reverse their "Read" status back to "Unread".

Rated 1 out of 5 stars

This is the extension i was looking for. Unfortunately I cannot use it because:
It does not work between IMAP and LOCAL folders. All emails are marked as new!
When an email message is stored in a local folder Thunderbird adds some extra control records. (x-mozilla....). Copy Folders should ignore these records when comparing IMAP and LOCAL folders.

Fonctionne a moitié Rated 1 out of 5 stars

Ne fonctionne que pour les comptes en imap apparemment. Ne fonctionne pas sur les comptes en pop (0 dossier, 0 message alors que le dossier est bien crée).
En imap je n'ai testé que sur une petite adresse email. Vu le problème sur le pop, je n'ai pas osé tester sur un compte contenant 16Go de mails ...

dommage ... avait l'air prometteur ..
