You have successfully logged off from Outlook Web Access. We recommend that
you close all browser windows at this time.

Are you still running the same Windows session now as you were before
(i.e., has Windows been running and you still logged on since your first
OWA use)? If so, have you look in the Processes tab of Task Manager
after you thought you closed IE8 to see if there were any remnant
instances of iexplore.exe still loaded?

Logged out of your Windows session and logged back in yet? Tried
rebooting yet?

Diane mentioned purging the web browser's cookies which you said didn't
help. Did you make sure ALL cookies got purged? If the Preserve option
is enabled under the delete settings then cookies for those sites don't
get purged.
