Peter, We are running Exchange 2003 SP1 as well and from what I know we have a cluster environment currently with a front-end server and one or more back end servers. When we turned on "REQUIRE SSL", information from delegated (shared) calendars was no longer being updated. The user can access his own calendar, mail, etc but can not access data from another person's calendar. With the SSL change, we had to check the Entourage Advanced setting to "Use SSL for WebDAV".
I have confirmed via a TCPDUMP on the Entourage client machine that Entourage attempts two SSL connections to the back-end server on a periodic basis but no traffic returns from the server. User mailboxes reside on the back-end server. All other traffic for the user's own data is being directed through the front end server (which is the exchange server name put in the Entourage setup windows). The back-end server host name appears NO where in the setup parameters of Entourage so Entourage is obtaining this information during the delegate connection to the shared mailbox or via a DNS lookup? I have spoken to Systems and the backend server does not have SSL enabled nor does it have a certificate. This seems to be the problem. Systems is going to set up a test environment to confirm this but that unfortunately will probably add weeks to a solution. Can you confirm that all your Exchange servers (front-end and back-end) have SSL enabled and certificates installed? I am using Entourage 2004 with SP1 (11.1). Bill Bryson p.s. I would be curious what a TCPDUMP might look like on your system. Here is the procedure to capture TCP/IP traffic to a log file in Mac OS X: Run Terminal in Utilities type: sudo tcpdump src [your-machines-IP-name-or-number] > log.txt Open up Entourage and access your Exchange information Quit Entourage Switch back to the Terminal window and type Ctrl-C to stop the capture of data by TCPDUMP The file "log.txt" will have lines containing all the TCP/IP traffic for the time interval. Here are some sample lines from my log file: 10:05:32.821289 IP mymachine.css.txstate.edu.50199 > backend.txstate.edu.https: S 13347914:13347914(0) win 65535 <mss 1460,nop,wscale 0,nop,nop,timestamp 1910336288 0> 10:05:32.922375 IP mymachine.css.txstate.edu.50200 > backend.txstate.edu.https: S 579396201:579396201(0) win 65535 <mss 1460,nop,wscale 0,nop,nop,timestamp 1910336289 0> 10:05:49.376087 IP mymachine.css.txstate.edu.50198 > front-end.txstate.edu.https: P 3600:4205(605) ack 3166 win 65535 <nop,nop,timestamp 1910336321 169281> -- To unsubscribe: <mailto:[EMAIL PROTECTED]> archives: <http://www.mail-archive.com/entourage-talk%40lists.letterrip.com/> old-archive: <http://www.mail-archive.com/entourage-talk%40lists.boingo.com/>
