I am running Exchange 2003 and Outlook 2003. When I open my Outlook on my desktop I can get e-mail from the exchange server. However, those items are not kept on the exchange server. Is there an easy way to fix this. I want the items to remain in the inbox on exchange so that when I view my inbox through OWA, I can see the e-mails. I don't know why they are being removed from the inbox. Any help would be greatly appreciated.

change the mail delivery location of your email account in control panel > email > accounts > exchange server from Personal Folders to Mailbox-Usename This happens when Outlook is setup to use PST and deliver mail to the PST file.
