Out of office not working behind proxy for Outlook 2007 users.
Out of office not working behind proxy for Outlook 2007 users.
- Hi Everybody,
I have upgraded my Exchange 2003 to Exchange 2007SP1. Everything works fine, except Out Of Office of Outlook 2007 users. Whenever they click on out of office message appears as " Your out of office settings cannot be displayed, because the server is currently unavailable. Try again later." Authentication for Autodiscovery in IIS is Windows Authentication and on EWS is Windows Authentication. All PCs are joined to domain. Out of office works fine in OWA as well as for other Outlook clients only issue with Outlook 2007 users. Another strange thing is if I de-select proxy settings in Internet Explorer connection settings, Out of Office box appears and works perfectly. As soon as enable proxy settings in Internet Explorer, message stated above again appears. What extra settings I need to do? Can somebody help me?

- What kind of proxy are you using? Is this a ISA?
If yes, Have you configured ISA to let through traffic to the /OAB directory. This is configured on the webpublishing rule and path tab
Also check and make sure that you have configured autodiscovery correct with all URL's containing names that are also in the used certificate.
Also have a look into the followin links

Raj - Yes, we are using ISA and it is configure for /OAB directory. Certificate contains all the URLs which we normally use to access the mailbox. Only thing I have observed is when I run get-WebServicesVirtualDirectory -identity "CAS01\EWS (Default Web Site)" |fl, nothing is displayed infront of externalurl field, i.e., externalurl is not defined. Is is necessary to define the externalurl?
Mukesh Sutar Ideally yes, you need to set the URL for EWS. Can you try setting the URL http://technet.microsoft.com/en-us/library/bb201695.aspx

Hi,
I agree with Rajinish. You need to configure the external URL for EWS.
Also you can publish the EWS virtual directory via ISA when you publish Outlook Anywhere.

- Hi,
It has been configured. I have configured External URL for ews and in ISA also EWS is publised, but nothing helped much. Getting the same error.
Mukesh Sutar - common friends, please help me to resolve this.
Mukesh Sutar - When I run Get-AutodiscoverVirtualDirectory -Server cas01 | fl InternalUrl,ExternalUrl, both URL are blank. Is this has to do something with the OOF? How I can set these two URLs?
Mukesh Sutar is your certificate properly set? Run these two commands
1. Set-OutlookProvider EXPR -Server $null -CertPrincipalName $Null
2. Set-OutlookProvider EXCH -Server $null -CertPrincipalName $Null
Raj- What will be the effect of this two commands?
I ran following command get-outlookprovider, output is as below
Name Server CertPrincipalName TTL
---- ------ ----------------- ---
EXCH 1
EXPR 1
WEB 1
What it indicates?
Mukesh Sutar - Can somebody help me?
Mukesh Sutar - We had this same issue and either adding the CAS server to the proxy exception list or ( in our case ) add *.yourdomain.com to the exception list in IE on the affected clients seemed to resolve it. We use an iPrism proxy server.
- Thanks. It worked without any glitch. problem has been resolved for users sitting behind proxy server. We are using squid as proxy server to access the internet. It didn't worked for users, whose machines are not joined to domain. I joined those machines to domain, logged in to domain with user id and password. I connected to net using dialup connection, and tried to set out of office, it worked.
Only problem remaining is, some top management user's machine are not joined to domain, they use administrator account to log into workstation. Do I need to change authentication settings on IIS on exchange CAS server? Current authentication is set to Basic+Integrated Windows.
Mukesh Sutar - That´s easy it means that when Outlook looks for the cas server´s the query goes to the proxy..just add the cas fqdn on the proxy exclusions to bypass.
cheers

MCSA - MCTS Exchange Server 2007 - If user is connected to internet via dial-up connection, whether exclusion in proxy settings does really matter?
