Hugely helpful Rated 5 out of 5 stars

Copying folders from dovecot imap (local) to gmail turned out to be very unreliable. For more than 10 messages, TB usually failed. This plugin seemed to do the job properly. Big thanks!

Not needed, didn't work Rated 1 out of 5 stars

I actually found the very easy way to copy folders from one IMAP account to another, and their emails - just select all the folders in one account and drag them over to the other account. No more complicated than that.

Won't load to TB 52.4.0 (64-bit) Rated 1 out of 5 stars

Maybe I'm doing something wrong...but I've tried every possible method and this add on will not load. Can someone help?

Does what is says Rated 4 out of 5 stars

Works fine for me in TB 56 (current beta version). Only issue is speed. It took ~15 minutes for 170 emails to get copied from one account to the other - in one main and two subfolders. This was a first test run, we see how the next one goes.
FYI, my folder structure was:
[main folder]
....|-- [subfolder 1]
........|--[subfolder 2]

does not work if you have subfolders Rated 1 out of 5 stars

tbird 52.3.0. copy folder worked for one folder from non-imap account to local folders, but failed trying to copy a folder that has subfolders to local folders. i wonder why many people reported that it works for them - are they copying folder/subfolder structures? or just single simple folders one at a time?

only "recent folders" shown Rated 1 out of 5 stars

Same problem described by elhennig, since the upgrade to TB 52

Still not able to choose destination folder Rated 1 out of 5 stars

Since some version s of Thunderbird I only get the recent folders to choose to copy the messages to, The other entries are missing. Please fix this or give me a hint, how I can fix it myself.

This user has a previous review of this add-on.

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?

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

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.
