We are using outlook 2010 and exchange 2010. We have a webfiltering software that shows websites being accessed. I will randomly see on the web filtering log that people are accessing https://server.domain.com/server.domain.com443. Is Outlook 2010 configured wrong, is the server configured wrong, any thoughts? I would think that Oultook would be connecting direclty to the server. Thank youEZ

Outlook uses Exchange Web Services for the offline address book, free-busy data, managing out of office and some other features. That URL you posted indeed looks wrong, so you might want to see if any of your virtual directories' ExternalURL or InternalURL settings are configured wrong. On a workstation running Outlook, hold the Ctrl key down, click on the Outlook icon in the system tray, select Test E-mail AutoConfiguration, enter your e-mail address and password, clear the Guessmart checkboxes and then click Test. You'll see the URLs that Exchange is providing to Outlook. Perhaps one of them is wrong.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

That is good, I should be seeing that traffic. I did the test as you suggested, I think it is ok. Internal OWA URL: https://"ServerName"."DomainName".com/owa Availability Service URL: https://"ServerName"."DomainName".com/EWS/asmx OOF URL: https://"ServerName"."DomainName".com/EWS/Exchange.asmx OAB URL: https://"ServerName"."DomainName".com/OAB/81600c58... On the log tab it shows: https://"ServerName"."DomainName".com/Autodiscover/Autodiscover.xml Succeeded. The ServerName is the internal computer name. Does this all look correct?EZ

Yes, then its fine, if you see format like you said above. But URL which you have posted in first post don;t look relevent.Anil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com

Agree. https://server.domain.com/server.domain.com443. is not a regular format. generally, the Exchange web-based service URLs look like below: https://servername/service/pagename/ for more informaiton, please refer to the link below: http://technet.microsoft.com/en-us/library/bb124251.aspx. Fiona
