  • Uses a user’s email address and password to provide profile settings to Outlook 2007, Outlook 2010, or Outlook 2013 clients and supported mobile phones.

2.What information the Autodiscover service returns to the client?

  • The user’s display name;
  • Separate connection settings for internal and external connectivity;
  • The location of the user’s Mailbox server;
  • The URLs for various Outlook features that govern functionality such as free/busy information, Unified Messaging, and the offline address book;
  • Outlook Anywhere server settings.

3.When the virtual directory handles Autodiscover service requests?

  • When a user account is configured or updated;
  • When an Outlook client periodically checks for changes to the Exchange Web Services URLs;
  • When underlying network connection changes occur in your Exchange messaging environment.

4.What two pieces of information does the SCP object contains?

  • The serviceBindingInformation attribute;
  • The keywords attribute.

5.What conditions Outlook 2007 automatically connects to the Autodiscover service?

  • Every time that the application starts;
  • At intervals on a background thread;
  • Any time that the client’s connection to an Exchange server fails.

6.For a certificate to be considered valid, what criteria for the Autodiscover service must meet?

  • The client can follow the certificate chain up to the trusted root;
  • The name matches the URL that the client is trying to communicate with;
  • The certificate is current and has not expired.

7.What are the solutions for certificate problems?

Not using a trusted certificate?

Use a 3rd party cert provider.

The certificate name does not match the DNS name\s?

Create a new cert request containing all the names used to access the server. Minimum of


<InternalName>.domain.local (if using for internal systems also)

Can’t resolve fully qualified domain names (FQDN)?

Make sure that the FQDNs for our external URLs as well as autodiscover have A records registered in DNS;

Verify we can access the autodiscover XML file

SCP Record does not contain the correct value?

Test from outlook:

– Hold CTRL and Click the outlook Icon in the system tray and select “Test Email Auto Configuration”

–  Deselect the “Use Guessmart” and “Secure Guessmart Authentication” and click Test.

Check SCP value returned

– If we get info on the results tab then AutoDiscover is working

– If not, go to Log tab and look at the URL that is returned

– Test the URL (Type it into Internet Explorer) if it is not working, change SCP to a valid URL, using Set-ClientAccessServer cmdlet.

– Set the SCP along with the internal URL: Set-ClientAccessServer CASServerName -AutoDiscoverServiceInternalUri https://mail.domain.local/Autodiscover/Autodiscover.xml
