Recently, there was a problem with the server and several times each day
Outlook 2007 asked me to enter my username and password for calendar sharing.
After doing this for a while I got tired of being diligent about what I
typed. Now it seems that the incorrect username and/or password has been
recorded in Outlook and I can no longer access any of my subscribed
calendars. I have deleted all cookies in IE8 but that did not work. Any ideas
how to reset things within Outlook so I can re-enter the publishing username
/ password? Thanks.
