@Carsten17: Blog comments are an important feedback mechanism that ties the Exchange community to the Exchange team. We review all comments, and a large number of comments and feedback are responsible for generating follow-up actions within the product
team. Such actions may not be immediately visible to customers, and include follow-up blog posts, creation and release of hotfixes or interim updates, documentation changes, and new product features or changes to existing features.
While we attempt to answer most questions posed in blog comments, we can't respond to each comment or question individually.
We recommend that you post questions related to your particular Exchange deployment in the Exchange forums on TechNet (http://social.technet.microsoft.com/Forums/en-US/exchange2010/threads),
where many community experts, including MVPs and Microsoft employees, can answer them. For assisted support, please contact CSS (https://support.microsoft.com/oas/default.aspx?&gprid=13965&&st=1&wfxredirect=1&sd=gn).
