I am using Outlook 2010. All day long I repeatedly get a popup asking for my password, for all 4 of my email accounts. The popup has the password populated, I click the box to "remember" and send it off, only to get it back again and again every 30-60 minutes or so.

This also happens to 2 other people that use Outlook in our small office - our PC's are on a MS SBS2003 server. 2 of us use XP Pro and one uses Windows 7 Pro. Any suggestions would be greatly appreciated.
