The reason why I didn't reply to your post was because I could not think of
any other solutions than the ones I had already posted. Many users
(including me) have come to the conclusion that the Mail importer is broken,
and the strategy I described in an earlier post (exporting Mail's folders as
..mbox folders and then importing them into Entourage) is the one I think to
be the most effective and reliable. As I said, there were other posts on
that same topic, and I invited the original poster to search the Google
archives for them. If I remember correctly, someone suggested renaming Mail
2.0's separate message files by changing their .emlx extension to .eml, and
then dragging the resulting files into Entourage. But it's all there in the
Google archives, in case you want to read more on this.
If these methods do not achieve the result you want, then I'm sorry, but I
can't help you any further. I don't know why the importer behaves the way it
does, nor do I know why it works for some people while it doesn't work for
others. In your special case, my guess would be that you installed Tiger on
April 30, and, as I've already said, Apple changed the way Mail messages are
stored with the new OS, so Entourage was only able to read the older
messages which you received when you were still using a pre-Tiger OS. This
is, I would think, a sound hypothesis which might explain why some of your
mail is missing, but it doesn't really get you any further, does it? So,
once again, try one of the above methods; you should eventually get there.
On a non-related note, I generally don't reply to personal e-mails, so
please use this discussion group for further questions; that way, it will be
beneficial for other users as well. If you don't get an answer to a post,
then it generally means that either people don't know the answer, or they
haven't had the time to post it yet.
