[EX2013] Simplify the Outlook Web App URL

1. Start IIS Manager.
2. Expand the local computer, expand Sites, and then click Default Web Site.
3. At the bottom of the Default Web Site Home pane, click Features View if this option isn't already selected.
4. In the IIS section, double-click HTTP Redirect.
5. Select the Redirect requests to this destination check box.
6. Type the absolute path of the /owa virtual directory. For example, type https://mail.contoso.com/owa.
7. Under Redirect Behavior, select the Only redirect requests to content in this directory (not subdirectories) check box.
8. In the Status code list, click Found (302).
9. In the Actions pane, click Apply.
10. Click Default Web Site.
11. In the Default Web Site Home pane, double-click SSL Settings.
12. In SSL Settings, clear Require SSL.



Note:

If you don’t clear Require SSL, users won’t be redirected when they enter an unsecured URL. Instead, they’ll get an access denied error.



13. For the new settings to take effect, open a Command Prompt window, and then type iisreset /noforce to restart IIS.
