We have the same problem. It seems to only happen when we have Outlook open
when the Exchange server is rebooted. Anyone else having this problem?

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!
