Die kenn ich schon.
Genau so hab ichs gemacht.
You can enable users in your corporate network to access Outlook Web Access. At the same time, you can deny access to external clients. The key to this approach is a combination of a recipient policy and a special Hypertext Transfer Protocol (HTTP) virtual server.
To use this approach, follow these steps:
1. Create a recipient policy with a Simple Mail Transfer Protocol (SMTP) domain name. Users who connect to an HTTP virtual server must have an e-mail address with the same SMTP domain as the virtual server. Creating a recipient policy is an efficient way to apply the same SMTP domain to multiple users.
Note Outlook Web Access users do not have to know the name of the SMTP domain.
2. Apply the recipient policy to the user accounts that you want to enable access for.
3. On the front-end server, create a new HTTP virtual server that specifies the domain that is used in the recipient policy.
Funktionieren tuts leider nicht.
