These are both problems when using the OWA access method. If you are using the web URL's to connect then NEITHER of these above items are available. Which BTW: Unless I'm going nuts, Outlook doesn't even allow you to connect via the OWA URL's on Windows Office Outlook.

However if you connect to the server directly or via VPN and NOT via OWA then both of these above items work.

For those who don't know about the OWA access method for Entourage, you need OWA for your company to be available from the Internet

Under Edit Account, Server Information, Exchange Server enter the URL: http://webmail.yourcompanyname.com/exchange
(WILL VARY, but make sure the /exchange is on the end - this URL will be the one you see once you are logged into OWA)

You *CAN* access Public Folders and Calendar from this method as well under Edit Account, Advanced Settings, Public Folder Settings, Public Folder Server:
webmail.yourcompanyname.com/public
(ENSURE NO http:// is in front of this - this URL will be the same as the above one, minus the http:// (or https:// and will have a /public at the end instead of a /exchange )
