We have over 150 Mac users all setup the same way, but only one is having the issue. The settings are EXACTLY the same on every computer including this one. What happens is you open up Entourage and the account connects but it will not pull down the folders, emails or, calendar items into the main window. The folder list does not populate, the calendar appears blank. The weird part is that the public folders list will populate, if you click on folder properties for the account it WILL pull all of the folders and their current sizes. If you give another entourage user delegate access, they can pull up the calendar items but not the email. We then configured entourage with MY account information on the same computer and it pulled everything correctly. We tried his account information on my computer, which is running Snow Leopard, and it had the same issues. We put his account information in Apple Mail on my Snow Leopard machine and it did pull all of his emails properly. So it seems to be something specifically with his account and entourage but our email admin cannot seem to see anything different that any of our other Mac users. Server Specifics: Outlook Web Access version: 220.127.116.11 Microsoft Exchange Client Access server version: 18.104.22.168 Mailbox server Microsoft Exchange version: 22.214.171.124 Entourage: Version 13.0.3 (091002) (We did just upgrade to 13.0.4 yesterday but it did not change anything) Any ideas?
