Getting DOUBLE EMAILS in MS Outlook 2007

[LivingInParadise]

My email goes to MS Outlook 2007 and to my BlackBerry Storm. Every once in a while (maybe every 10 days) I get a whole set of double emails in Outlook.

Anyone know why? How can I stop this from happening? Thank you.

Your incoming email is duplicated in Outlook but not on your BB? That sounds like an issue with your mail server/Outlook. I don't think it's a blackberry issue Either it is failing to send the correct response code when the incoming message arrives so the sender's server transmits again, OR the messages are not marked in the Outlook list so it gets them twice from the mailbox.
