In order to use Microsoft Outlook to connect to your Virtuworks Hosted Exchange account, it is necessary to setup Outlook Autodiscovery. This will enable Outlook to retrieve and configure your account settings automatically from the Virtuworks mail server. This will also prevent any errors from occurring due to misconfiguration. There are a few steps required to setup autodiscovery for your domain.


If your DNS is hosted with Virtuworks, or you would like Virtuworks support team to perform these actions on your local network:

If your DNS is NOT hosted with Virtuworks and you would like to perform these actions yourself, follow the steps below:

Note In order to make the following changes to your network configuration, you should have administrative permissions to modify the DNS record for your domain.

If you have multiple primary SMTP address domains in your organization, you must create an Autodiscover SRV record in each zone.

  2. Use the following parameters to create a new SRV record:
    Service: _autodiscover
    Protocol: _tcp
    Port Number: 443

  2. Autodiscover posts to This fails.
  3. Autodiscover performs the following redirect check:

    This fails.

  4. Autodiscover uses DNS SRV lookup for, and then “” is returned.
  5. Outlook asks permission from the user to continue with Autodiscover to post to
