Every half hour, Outlook Mail requests I re-enter my password for a synced account (exchange account). Is there any way to save the password so I am not constantly prompted?

Thanks in advance.

Please check if this article Fix For Outlook 2007 Constantly Asking for Password on Vista helps.

In my case I tick "Save Password" but prompt didn't stop. This article resolved my password prompt
