To my knowledge, he doesn't get an error message. Using the slipstick method, he sees my regular calendar, but the sub-calendar just isn't there. Using the "open a shared calendar" or File | open | Other User's Folder does the same thing. I've gone through all of the properties and sharing menus of my mailbox, inbox and calendar, but he is listed in those names exactly the same as everyone else. I dont know why he wouldn't be able to access it but everyone else can.
I dont have 2002 so I dont know what he's looking at. If I did, I might be able to figure it out, or at least tell him where to click, but I was told his view is completely different from what I have.
Thank you for trying to help! Still hoping ...
