CAUSE
This issue occurs if one of the following conditions are true:
 * The Exchange virtual directory is configured to require Secure Sockets Layer (SSL).

-or-
 * Forms Based Authentication is activated on the Exchange virtual directory.

Outlook Mobile Access uses the Exchange virtual directory to access Microsoft Outlook Web Access (OWA) templates on the Exchange back-end server that contains the user’s mailbox. When the Exchange virtual directory is configured to require SSL or if Forms Based Authentication is activated, Server ActiveSync and Outlook Mobile Access cannot access the Exchange virtual directory. This problem does not occur when these settings are activated on the Exchange virtual directory on a front-end server.



RESOLUTION
To resolve this issue, use either of the following methods:  Activate SSL or Forms Based Authentication on front-end Exchange servers only. Follow these steps to activate SSL or Forms Based Authentication on back-end Exchange servers:  Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager. Locate the Servers/ /Protocols/HTTP/Exchange Virtual Server folder. Right-click Exchange Virtual Server, click New, and then click Virtual Directory. Type the name of the new virtual directory that Server ActiveSync and Outlook Mobile Access will use. For example, type /Exchange-oma.

Note The name that you type is not the name of the virtual directory that OWA clients connect to.</li> In the Exchange Path section, click Mailboxes for SMTP domain, and then make sure that the correct SMTP domain is listed.</li> Click OK to return to Exchange System Manager.</li> Click Start, click Run, type regedit, and then click OK.</li> Locate and then click the following registry key:

</li> Click the  key.</li> On the Edit menu, point to New, and then click String Value.</li> Name the new key that you created in step 10 &quot;ExchangeVDir&quot;.</li> Double-click the ExchangeVDir key, and then type name of the virtual server that you created in step 4 in the Value Data box.

For this example, type /Exchange-oma .</li> Click Start, point to Programs, point to Administrative Tools, and then click Internet Services Manager.</li> Right-click the virtual directory that you created in step 4, and then click Properties.

In this example, the virtual directory is named /Exchange-oma .</li> Click the Directory Security tab.</li> Under IP address and domain name restrictions, click Edit.</li> Click Denied access, and then click Add.</li> Click Single computer.</li> Type the IP address of the server that you are configuring in the IP address box, and then click OK.</li> <li>Click OK to return to the Directory Security tab of the virtual directory properties page.</li> <li>Under Anyonymous access and authentication control, click Edit.</li> <li>Verify that the Integrated Authentication check box is selected. If the Integrated Authentication check box is not selected, click to select this check box.</li> <li>Click OK.</li> <li>Under Secure communications, click Edit. Make sure that Require secure channel (SSL) is not selected.</li> <li>Click OK to close the remaining dialog boxes.</li> <li>Repeat steps 3 to 20 for each of the back-end servers where SSL is required for the Exchange virtual directory or where Forms Based Authentication is activated on the Exchange virtual directory.</li> <li>Click Start, point to Programs, point to Administrative Tools, and then click Services.</li> <li>Stop and restart the World Wide Web Publishing service.</li></ol> </li></ul>
