I generally set all of my folders to offline mode, but do *not* set my
accounts to Sync... that way, I basically get 'Sync on demand' (only
messages that I actually click on are downloaded).I do this mainly to
avoid having to download attachments repeatedly (in my business we deal
with a lot of large attachments).
So, I do have the mbox files, although they are generally very small
compared to how much mail is in the folder...

The only other thing I can think of is some kind of AV on the local
computer, but it seems like that would affect OE too - unless you had
configured it to not scan OE connections...

It would be good if you could confirm this, but, I think that if its a
config issue, its more likely a TB config issue (especially since OE
seems to not have a problem) - too bad TB doesn't have a way to dump the
config changes like dovecot/postfix...
Did you make any manual config changes to TB using about:config or
applying manual changes to user.js?
