Other Calendars list has dissappeared from Navigation Pane

My "Other Calendars" list has dissappeared from my navigation pane in
Outlook 2003 SP1. I am pretty sure I deleted it while trying to
troubleshoot another problem. The shared calendar I want to view side
by side with my own is in a public folder. I could do it before when I
had the "other calendars" list but now it won't let me "Add to Other
Calendars". Is there any way to restore this list to the navigation
pane? I can't add shared calendars without this list.

Thanks,
Jeff

Ok, I finally figured it out....or at least I was able to hack a way to
do it. In my file C:\Documents and Settings\myusername\Application
Data\Microsoft\Outlook\MS Exchange Settings.xml, the sharedcalendars
section was missing. So I copied it from somebody else (I had to copy
the whole thing even though I don't need all of the calendars that he
did) and pasted it right after the calendars section with outlook
closed. When I opened outlook again, the "Other Calendars section was
there again and I could use it as I could before.
