in a customer with exchange 2007 over windows 2008 all the sudden out of office stopped working from outlook 2007 and 2010 clients, the only thing they did was to renew the self-signed certificates i've checked this thread http://social.technet.microsoft.com/Forums/en-GB/exchangesvrclients/thread/b27f77c3-6b88-43b8-a07a-4040ffe8c05e and the 3 virtual folders marked in the proposed solutions are already as told. testing with an outlook 2003 client worked perfectly any other ideas? edit: i ran test-outlookwebservices and this is the output: Id : 1003 Type : Information Message : About to test AutoDiscover with the e-mail address Administrator@semino.com.ar. Id : 1007 Type : Information Message : Testing server DS01.domain.com.ar with the published name https://ds01.semino.com.ar/EWS/Exchange.asmx & .

Hello, The issue happened on internal or external? Is it working on owa website. Please run GET-Webservicesvirtualdirectory |FL, get-autodiscovervirtualdirectory |fl and check the result. Best Regards, Lisa

You shouldn't be using self signed certificates, as they are not designed for production use. If you have simply renewed them then it looks like the SSL certificate is corrupt. Remove and recreate, or better still replace with a commercial SSL certificate with the relevant names in it. http://exchange.sembee.info/2007/install/multiplenamessl.asp Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK?

there's only internal site, in owa it's not working either Lisa, if i enter that command as it is it returns an error in the comma: Missing argument in parameter list. At line:1 char:37 + GET-Webservicesvirtualdirectory |FL, <<<< get-autodiscovervirtualdirectory |fl if i remove the comma, it returns empty, or you meant two different commands? i've run them separate and they simply return a list of the virtual directories, i don't see anything wrong in them. Simon, they simply renewed the old cert, so the names are correct as all the data should be the same except expiration date(they won't use commercial ssl certs, there's no need to incur the cost for this installation) Also, from OWA it works perfectly edit2: i did a test autodiscover from the O10 client and it returns error 0x800C8203 what i do find odd its that i can access autodiscover url WITHOUT HTTPS, with http it works ok, but https directly fails. how do i need to have the virtual server configured?, does it need to have required HTTPS and 128bit enabled? edit3: i've enabled the require ssl and 128bit, the https site fails to load directly but http works.... any idea? edit4: i seem to have fixed it, since the certificate was the suspicious thing, i did a get-exchangecertificate and noticed that IIS was not on the list of enabled services, so i enabled it for IIS as well and now the autodiscover webstie can be browsed succesfully from a browser and out of office appears to be working

Is the server not being accessed from the internet at all? If not, then continue to use self signed certificates. If the server is being accessed from the internet then you should use a commercial certificate. Simon. Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
