894035 - No error when copying IMAP folders between accounts fails

Status: UNCONFIRMED

(Thunderbird :: Folder and Message Lists, defect)

Description

[Bear]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.72 Safari/537.36

Steps to reproduce:

I dragged an imap folder from my Gmail account to my Dreamhost account.


Actual results:

Attempt 1: The folder was copied.
Attempt 2: The folder was copied.
Attempt 3: Nothing (literally).


Expected results:

When copying a folder from one account to another using IMAP the user should be notified when there is a problem and appropriate server error messages, if present, should be provided.

Additionally, no errors are present in the error console.

When I drag the folder and drop it, literally nothing happens.

Comment 2

I have discovered that I can copy one folder each time Thunderbird is restarted.

Comment 3

When I try to copy a folder with subfolders I get:

The current command did not succeed. The mail server for account [account name] responded: [TRYCREATE] Mailbox doesn't exist: INBOX.[folder name]^^[subfolder name].

It looks like the receiving IMAP server is trying to create the folders with the same special characters used by Gmail and failing; that Thunderbird is failing to report this.

I have narrowed down the problem:

Anytime Thunderbird encounters an unhandled error when moving messages in IMAP, it does not present an error and it refuses to process further move commands.

So dragging and dropping a folder after an error occurs means nothing happens when the folder is dropped.

I have around 30GB email to move them from IMAP to Local folder. There is no solution in Thunderbird if this won't be fixed.

This is still an issue. I just copied 500 messages to outlook.com and only about 200 made it. No error message.
