Using Moz .9.3, I get 'Unknown Error 80470002' when compressing mail files.

I'm guessing one of the files is corrupt, but it'd be nice to know which one so
I can fix it by hand.

Can you attach the folder data file (found in your mozilla/mail/* directory) as
an attachment here? Do you have any testcase so we can reproduce this bug? Can
you try a later nightly build (downloadable from

I can't attach a test case because I don't know which folder is causing the

OK, I feel better now.

I'll try one of the nightly builds and start searching for the offending folder.

Never mind, I can't reproduce it any more.  I think it was a .msf file that was
corrupted, since it disappeared when I deleted some of them.  Be nice if the
front-end let me know which file it was, though.  Sigh.

Good news is that this is by far the best mail reader I've ever used, and
perhaps even the most stable (with the stability stuff that went into .9.3 -
before that it was a dog).

No. I don't think this is dup of bug 97497.
I actually saw this alert one or two times before on IMAP.
But I couldn't reproduce it again......

You can compact them one by one using right click menu on a folder "Compact This
folder" to find out which one is doing and when you find the folder, try 
deleting the msf file for that folder. Allow it to be built again and then 
try compacting it again. I think it will most probably fix the problem

Is this still a problem on recent builds. Please comment. Are u seeing this on 
newer profiles?  If so please mention the folder name causing the problem.

I had the same problem, but upgrading to 0.9.4 fixed it for me. Have not had a
problem with compressing folders since.

Problem seems to be fixed as of around .9.4.

FYI, I haven't seen this happen in quite some time. I _think_ it went away in
0.9.8, but wouldn't swear to it.
