Remote web access Shared Calendar

[nortelfan]

I am trying to create a shared calendar for use on SBS 2003 Exchange. When I access the remote web interface and go into Outlook, I have no problem. When I go to Pulic Folders and right click to create a new folder, I can enter the name and then try to select Appointments as the "Folder contains", but the system pops up a login windows saying my session has expired. I can log back in and try again and it does the same thing.

I can add to my calendar fine, but for some reason I get this strange action everytime I try to create a public folder. I am a member of administrators and domain admins.

Thanks
