Configuring Outlook 2003
We only recommend the use of Outlook for users of Microsoft Exchange. The following instructions are for those who, through personal choice, wish to use Outlook for IMAP email.
Open your Tools menu at the top of the screen and select email Accounts. Then select "View or change an existing account". These settings should already be correct, but check them to be sure. Note that you should not tick the SPA box, and instead click on the "More Settings..." button.
Pressing "More Settings..." brings up this tabbed window. Move across the tabs ensuring that your details are correct.
