Windows live mail does not download all of my mail

That's strange! Is there anything common to the messages it isn't downloading? (E.g., from a certain folder, from a specific sender, etc.)

No. The messages are from a variety of senders. I can't see anything common.

I spoke with a tech at my server. We moved all the messages in this account to a temp folder, deleted the account, then reestablished the account, with all the appropriate settings, and it now worked correctly. We then moved the messages in the temp folder back into the correct inbox. Hope this helps if anyone else has this problem.

Glad you got it fixed!
