Of course, fixing the cause makes sense when possible, but if Outlook and
other tools all work OK, then it is a bug in spambayes that we don't.

Excellent!  The more common pattern is to catch pythoncom.error, but
pywintypes.com_error is an alias for the same object, so your code is just
fine.

The only thing is that we are wrapping the recursive call to
_BuildFolderTree in the exception handler.  I would generally prefer to only
catch the operation in error.  Is it possible for you to include the full
traceback without this patch applied?  Then I will get it into CVS.

Thanks for digging in to find this problem!

Mark.
