outlook 2007 not saving username and password

[gaz003]

One of the directors uses Microsoft outlook as their main e-mail and links to the live@edu system, I set this up from the office and it logs on OK each time with no issues nor does it ask for the users e-mail address and password. This user also used the English room to teach, when they logged on and clicked on outlook it asked for their username and password, I thought it might have being a windows update issue but it seems that any machine she logs on to she has to manually enter these details – it doesn’t automatically save the settings in the users profiles? Is there any way around this?
