SYMPTOMS
When you try to log on to Outlook Web Access (OWA), you may be prompted for credentials three times, and then you may receive the following error message:

You are not authorized to view this page You do not have permission to view this directory or page using the credentials you supplied.

HTTP 401.1 - Unauthorized: Logon Failed

Internet Information Services



RESOLUTION
To resolve this issue, follow these steps.

Step 1: Verify Exchange Virtual Directory Settings

 * 1) Start Exchange System Manager. To do this, click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
 * 2) Expand Servers, expand  , expand Protocols, expand HTTP, and then expand Exchange Virtual Server.
 * 3) Under Exchange Virtual Server, right-click the Exchange virtual directory, and then click Properties.

Important Make sure to verify Domain Name System (DNS) settings and to verify the e-mail domain of the user who is experiencing this issue. If the e-mail domain is set incorrectly, you can resolve this problem by setting the e-mail domain correctly.
 * 1) Click the Access tab, and then click Authentication.
 * 2) Click to select the Basic authentication check box, if it is not already selected.
 * 3) In the Default domain box, type \ (the backslash character), if it is not already present.
 * 4) Click OK, click OK again, and then quit the Exchange System Manager snap-in.

Step 2: Verify Default Web Site Properties

 * 1) Expand Default Web Site, right-click the Exchange virtual directory, and then click Properties.
 * 2) On the Virtual Directory tab, verify that the Local Path box points to the M drive, and then make a note of the path.
 * 3) Verify that the Application name box contains the Exchange virtual directory application.

NOTE: When a valid application is displayed in this box, the Create button is not displayed. Instead, a Remove button is displayed next to the Application name box. If a Create button is displayed next to the Application name box, click it. Exchange then appears in the Application name box.
 * 1) Click the Directory Security tab, and then click the Edit button under Anonymous access and authentication control.
 * 2) Click to select the Basic authentication (password is sent in clear text) check box, if it is not already selected.
 * 3) Under Authenticated access, click the Edit button.
 * 4) In the Domain Name box, type \ (backslash character) if it is not already displayed.
 * 5) Click OK, click OK, click OK, and then quit the Internet Information Services snap-in.

Step 3: Verify Exchange Recipient Policy

 * 1) Start Exchange System Manager.
 * 2) Expand Recipients, and then click Recipient Policies.
 * 3) In the right pane of the Exchange System Manager window, view the Properties pages of the recipient policies to determine if an SMTP address that corresponds to the folder in the M drive (which you noted earlier in step 6 of &quot;Verify Default Web Site Properties&quot;) is listed on the E-Mail Addresses (Policy) tab.
 * 4) In the left pane of the Exchange System Manager window, click Recipient Update Services under Recipients.
 * 5) In the right pane, right-click Recipient Update Service (Enterprise Configuration), and then click Rebuild. Click Yes to confirm this operation.
 * 6) Right-click Recipient Update Service (Enterprise Configuration), and then click Update Now.
 * 7) Right-click Recipient Update Service , and then click Rebuild. Click Yes to confirm this operation.
 * 8) Right-click Recipient Update Service , and then click Update Now.
 * 9) Quit the Exchange System Manager snap-in.
 * 10) Wait for a few minutes to allow the Rebuild opeartion and the Update operation to complete, and then test Outlook Web Access (OWA) from a client computer.
