Hi James,

have a look on this site with descriptions:

I prefer to export the calendar into a PST file (that is stored on the
desktop) and this PST file, you can send via email.

The receiver can open this PST file very easy. He must save the PSt file on
the desktopn and open it in Outlook under "File/Open/Personal Folder PST"

How to export a folder in Outlook into a PST file:

le.htm

another way is described on this site:

"Can I send my Outlook calendar to someone by email?"

Maybe it help.
