For some reason, in the past week, it keeps re-loading the thousands of emails that I have already read.  I checked with my email service and went through some tests; they said it was an Outlook issue.  I rebuilt the database to no avail.  In Prefs>Reading, I have always had checked "Mark Mail as Read"--Never and had not had a problem until now.  Otherwise, the accounts that I have set up seem to work just fine.

I searched here and could not find an answer.

Please help!

Thanks.
