486952 - After migration from Outlook folders are empty

Status: RESOLVED WORKSFORME

(Thunderbird :: Migration, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9.0.8) Gecko/2009032711 Ubuntu/8.10 (intrepid) Firefox/3.0.8
Build Identifier: 2.0.0.21

Process of migrating a 700 MB Outlook pst file to Thunderbird version 2.0.0.21 on Windows XP SP2 platform.

Step 1: Outlook is default email client. Installed Thunderbird. After first launch went for the Import wizard. Settings didn't import - errors. I didn't follow up as I rather set this configurations by hand in Thunderbird.
Step 2: Import of address book went fine.
Step 3: Import of folders. Thunderbird imported all folders and email properly into a folder call Outlook in the Local Folders directory. Around 120 folders in 6 levels with approximately 1200 emails stored for reference.

All email are marked unread. There is presently no function in Thunderbird to mark all email in all folders read. That means all that had to be done by hand. 120 times to go to each folder and mark folder read.

Copy/Move the imported folders inside Thunderbird via drag-and-drop copy/moves sub folders and and emails only partly but not complete. The folder size showed 0 Kb.
The solution is to close Thunderbird and do the copy/move entirely in the file manager (Explorer). For that 3 files per folder (all files with the same name but different file extensions) (only parent folders have to be copied) have to be copied/moved from the Local folder directory to the destination directory. 
The move/copy works fine as long as the mailbox is small (for home use) but when migrating office mail boxes this problem occurs.

Reproducible: Always

Steps to Reproduce:
Step 1: Outlook is default email client. Installed Thunderbird. After first launch went for the Import wizard. Settings didn't import - errors. I didn't follow up as I rather set this configurations by hand in Thunderbird.
Step 2: Import of address book went fine.
Step 3: Import of folders. Thunderbird imported all folders and email properly into a folder call Outlook in the Local Folders directory. Around 120 folders in 6 levels with approximately 1200 emails stored for reference.
Actual Results:  
Folders with several layers (subfolders) don't copy with all emails included 

Expected Results:  
Copying folders with several layers (subfolders) should copy with all emails included

This bug is still valid. Migration of large mailboxes within TB is dangerous and leads very often to incomplete folders. I have not tested this on TB3 as Lucid is on the way and we are working on LTS versions only.

Juergen/Blue .. can you retest with version 3.1 or (better yet) 3.3alpha?

I have no test files any more with loads of meails. All users got migrated in the last year :-)
However TB 3.1 looks much more stable and so far I didn't have a loos. However - before moving folders with 100 or more emails I do make a copy first.

RESOLVED INCOMPLETE due to lack of response to last question. If you feel this change was made in error, please respond to this bug with your reasons why.

I have not any problems with migration of large folders after TB version 3.1
