Thanks for the quick reply madman. I thought as well that you'd need an exchange server, but outlook 2003 will allow internet publishing:
----Quote from MS help site (see link in first post)---
For organizations that do not use Exchange Server
If your organization is not using Exchange Server, you need to set up your computer so that Outlook 2003 can access users' schedules. Before you can access your team members' schedules or allow them to access yours, all team members need to publish their free/busy information and set their free/busy search locations.
[...]
Free/busy status information can be stored on a local server on the LAN or on a remote server by using a file path, FTP, or HTTP.
[...]
If team members are located outside your network, everyone can publish their free/busy information to an FTP or HTTP server. Or you can use a combination of the two publishing methods if needed.

So, I think it is possible without Exchange server. Leaves the question of security, where setting ftp access hopefully comes in. Here's an example link they use, and I hope to find something like this for TCH that works... ftp://myName:myPassword@ftp.tailspintoys....ules/%name%.vfb
I tried to set up ftp accounts in panel, but the accounts appeared under the public_html folder. I can't find info on this ftp stuff at TCH. I'm not a complete newb to ftp either, I've been using an ftp client for years to upload websites (although I let FrontPage 2003 do it now).
