Can I share Outlook 2007 calendar with Outlook 2003 users?

I am currently using Outlook 2007, Vista. I am trying to share my Outlook
calendar with other 2003 Outlook users. So far I am unsuccessful.

How are you trying to share it?

I am trying to set up a master calendar in Outlook 2007 and then share it
with Outlook 2003 users. I can share with a fellow Outlook 2007 user and am
unsuccessful sharing it with Outlook 2003 users... Any thoughts on how I can
do this? Thanks Diane.

I am trying to share it through Outlook... Right click on the calendar and
choose "share calendar", then sends email to whom I want to share with. Opens
with fellow 2007 user but not with 2003...
