I have also been assisting a couple users with the same problem in
Thunderbirs version 6 (can't create sub-folders like you used to
in TB - older versions).
I've gotten it to work, but rather wary of this solution:
We were told in the past (Client Svcs.
colleages) to be sure the first 2 check-boxes under the
Advanced server settings were NOT checked
( Show only subscribed folders, and,  Server supports
folders that contain sub-folders and messages), and this has
worked for using folders/sub-folders up until now.
My co-worker and I tested by checking that 2nd box, and then I
was able to create a new folder (to contain only folders), and
then created a sub-folder within. I closed and re-launched TB
and I could see both. I then turned off that setting, closed
and re-launched again, and then was NOT able to create another
sub-folder (but this method works for now).
I am able to create a new folder with a sub-folder in Webmail
and it shows up fine in TB. I use both TB and Webmail at home
and have not had
issues with finding my stored messages.
Not sure if that's entirely helpful but you could try it. I
looked on Mozilla's site and did other searches, and I also
contacted the Helpline last week but wasn't able to glean much
else. These are some tips the Helpline gave me:
1) Click the "View" tab, then click
"Folders," and make sure that "All" is selected.
2) Reinstall Thunderbird. You can do this by uninstalling and
then reinstalling following the directions at this website: http://www.mozilla.org/en-US/thunderbird/6.0/releasenotes/
and clicking first on the instructions for uninstalling, then
on the instructions for reinstalling. As the website says, you
will not lose your data, as the data is stored in the profile
folder stored at a separate location. If you try both of
these things and you are still not satisfied, you can try
contacting Mozilla at their website.

We've been experiencing some erratic behavior from Thuderbird when
attempting to create subfolders. We create a folder that holds
"Folders Only" properly but when attempting to create the
subfolders the "New Folder" option is not always available. You
can create one new subfolder and then the "New Folder" option is
not available for subsequent folder creation. When restarting
Thunderbird the option is available again but you can use it only
once. The only way to get it to work properly is to start
Thunderbird in Safe Mode and have all Add Ons disabled.
If you are clicking on the main account>New Folder>Create as
a subfolder of: you cannot select "choose this for the parent"
for any subfolder.
This sounds crazy but I was able to reproduce this on another
machine and have had reports of the same behavior from other parts
of the office.
Anyone have any insight?
