when a cleint connects via OWA they are able to view free/busy information, but my outlook 2007 clients simply say: "No busy/free information could be retrieved". I checked client side and control right cliking and then selecting test e-mail autoconfiguration returns the following XML<?xml version="1.0" encoding="utf-8"?><Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006"><Response xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a"> <User> <DisplayName>Me</DisplayName> <LegacyDN>/o=SMTPdomain PTA/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=Me</LegacyDN> <DeploymentId>cb4389e1-7d04-40aa-bf36-74d6a24e79c0</DeploymentId> </User> <Account> <AccountType>email</AccountType> <Action>settings</Action> <Protocol> <Type>EXCH</Type> <Server>hermes1.SMTPdomain</Server> <ServerDN>/o=SMTPdomain PTA/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=HERMES1</ServerDN> <ServerVersion>720082AD</ServerVersion> <MdbDN>/o=SMTPdomain PTA/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=HERMES1/cn=Microsoft Private MDB</MdbDN> <ASUrl>https://owa.SMTPdomain/EWS/Exchange.asmx</ASUrl> <OOFUrl>https://owa.SMTPdomain/EWS/Exchange.asmx</OOFUrl> <UMUrl>https://owa.SMTPdomain/UnifiedMessaging/Service.asmx</UMUrl> <OABUrl>http://owa.SMTPdomain/OAB/6de0cdee-64bc-468f-92e2-3f2b69bd56a5/</OABUrl> </Protocol> <Protol> <Type>EXPR</Type> <Server>mobile.SMTPdomain</Server> <SSL>On</SSL> <AuthPackage>Basic</AuthPackage> <ASUrl>https://owa.SMTPdomain/EWS/Exchange.asmx</ASUrl> <OOFUrl>https://owa.SMTPdomain/EWS/Exchange.asmx</OOFUrl> <UMUrl>https://owa.SMTPdomain/UnifiedMessaging/Service.asmx</UMUrl> <OABUrl>http://mobile.SMTPdomain/OAB/6de0cdee-64bc-468f-92e2-3f2b69bd56a5/</OABUrl> </Protocol> <Protocol> <Type>WEB</Type> <External> <OWAUrl AuthenticationMethod="Fba">https://mobile.SMTPdomain/owa</OWAUrl> <Protocol> <Type>EXPR</Type> <ASUrl>https://owa.SMTPdomain/EWS/Exchange.asmx</ASUrl> </Protocol> </External> <Internal> <OWAUrl AuthenticationMethod="Basic, Fba">https://mobile.SMTPdomain/owa</OWAUrl> <Proocol> <Type>EXCH</Type> <ASUrl>https://owa.SMTPdomain/EWS/Exchange.asmx</ASUrl> </Protocol> </Internal> </Protocol> </Account></Response></Autodiscover>Test-Outlookwebservices returns the following: Id : 1003Type : InformationMessage : About to test AutoDiscover with the e-mail address Administrator@SMTPdomain.Id : 1007Type : InformationMessage : Testing server owa.SMTPdomain with the published name https://owa.

check your OAB virtual directory. yours is set to http, needs to be https. Set-OABVirtualDirectory -Identity "server\oab (Default Web Site)" -InternalUrl https://owa.smtpdomain.com/oab Hope that helps.

Fixed it, but no change. One thing I did notice, if I go to the autodiscovery.xml file via internet explorer it ask me to authenticate, I have to enter domainname\username and password before I get the right bit of XML back, is this correct? I tried test-outlookwebservices again but with my details instead of it going default with administrator and got a bit less this time around:S] C:\Documents and Settings\Administrator.SMTPDomain>Test-OutlookWebServices -Ientity:me@SMTPDomain | flId : 1003Type : InformationMessage : About to test AutoDiscover with the e-mail address me@SMTPDomainId : 1013Type : ErrorMessage : When contacting https://autodiscover.SMTPDomain/autodiscover/autod iscover.xml received the error The underlying connection was closed: Unable to connect to the remote server.Id : 1013Type : ErrorMessage : When contacting https://autodiscover.SMTPDomain/autodiscover/autod iscover.xml received the error The operation is not allowed on non-co nnected sockets.Id : 1006Type : ErrorMessage : Failed to contact AutoDiscoverMaybe something wrong with the way autodiscover site in IIS autenticates?

Small update, when I enable loggin on outlook 2007 I get the following error in the olkas logs, Sending requestRequest sentResponse error code: 00000000HTTP status code: 0----------------------------------There is an error in request/response.XML response:-----------------------------------Getting ASURLFailed to get ASURL. Error 8004010FThat error seems to be as generic as saying there is something wrong with my autodiscover, does it mean anything to anyone?

Yeah, it's so helpfulthank you

so..so.. great answer

make sure you have intergrated authentication enabled on your IIS virtual directory for the autodiscovery vdir.

I am having this same issue - what did you do to solve this? I appreciat any assistance! Thanks.
