If you have configured OWA redirect in my case through TMG (Setting up an OWA Redirect in Forefront TMG 2010), you will see the following notification for a while:
Your browser will be automatically redirected. If your browser does not support automatic redirection, browse to the original URL again.
If your browser does not support automatic redirection, you will see ONLY the notification despite of successful authentication.
How to enable automatic redirection:
- Open Internet Explorer or Control Panel
- Internet Options
- Click the “Security” tab and click the “Custom Level” button
- Click the “Enable” radio button underneath the “Allow META REFRESH” header.
- Close and reopen browser to finish enabling automatic redirect.
