Recently upgraded to Outlook 2007 and found that the shared calender list I
had in Outlook 2003 was no longer there. I re-opened the calendars to have a
list of "People's Calendars" again, but after a couple of days of shutting
down and rebooting in the evenings, the calendar list (other than my personal
calendar) is gone and I have to re-select/re-open the calendars. Has anyone
else had this problem and do you know of a solution so I don't have to repeat
the selections every few days?

Thanks for your help!
