Due to these postings I was able to install and configure Exchange 2013.
Very nice job!
Also, I have a problem:
I created a Distribution Group,
On the "Group Delegation" property of which I added a "username" to the "Send As" option.
In the mailbox of that "username" I activated "Show From" - but only that "username" appeared (no Distribution Group name)?
Thank You,
