I don't have actual ideas on the problem, but I can offer up some help 
on how to debug it. Save the below as "runtbird.bat" and place it on the 
user's desktop, and tell them to run this instead of the ThunderBird 
icon. This will log all the debug info from the client so you can go 
through it:

== snip ==
set mydate=%date:~-4,4%%date:~-7,2%%date:~-10,2%
set mytime=%time:~0,2%%time:~+3,2%

set NSPR_LOG_MODULES=IMAP:5
set NSPR_LOG_FILE=c:\thunderbird_%mydate%_%mytime%.log

start /d "c:\program files\mozilla thunderbird" thunderbird.exe
== snip ==

Obviously adjust the log location and ThunderBird install folder as 
appropriate. If you want to log all modules instead of just IMAP (SMTP, 
e.g) then replace "IMAP" above with "all".

Note the above will create a date/time stamped logfile for each run, so 
you won't lose the previous logs. The 'mydate' and 'mytime' are a little 
bit of smarmy batch-fu, make sure you get all those percent chars and 
whatnot in your copy/paste.
