In September 2010 we told our Live@edu customers about a required URL change for connections to Outlook Web App to support better interoperation with Live ID.
This URL change requires schools to now use the URL http://outlook.com/<domain> to access Outlook Web App. You also have to modify any single sign-on solutions to reflect the URL change. After posting the original message, we heard from many customers that more time would be required to test integration and the deadline to make the required changes was extended to March 1, 2011.
This date is now here, and we would like to remind our Live@edu customers to make this change. However, we have revised our implementation plans and your current solutions will continue to work beyond March 1. Please do make the change before June 30, 2011 to ensure that your users do not experience problems and your organization is prepared for future platform changes.
We have summarized the required changes below for your convenience.
URLs that go directly to Outlook Web App, such as http://outlook.com or http://outlook.com/owa should be changed to go to http://outlook.com/<your domain name> - for example, http://outlook.com/contoso.edu. To prepare for URL changes:
If you are using the URL http://outlook.com/ecp to access the Exchange control panel management interface, you will also want to modify that URL to look like this: http://outlook.com/ecp/?realm=contoso.edu.
Single sign-on solutions using the Live@edu SSO toolkit must make the following changes:
Custom solutions have to make this change also, though the location will vary.
In addition, we have seen some cases where Live ID removes URL parameters, resulting in undesired behaviour. To mitigate this issue, we advise that all single-sign-on solutions add the parameter exsvurl=1 as a setting in the URL. This setting will force the URL parameters to be preserved. Typically, the setting is appended to the end of the redirection URL and preceded with an ampersand, like this: https://outlook.com/edu&exsvurl=1.
