Hello fellow expert-exchangers,
I am in the middle of rolling out a new SBS Standard 2011 install. I have configured Exchange, I am able to send and receive emails with no problem. The question I have is I need some end users to be able to receive and send from other email accounts. I have gone through all the permission settings for the accounts I want the end users to use. I have given the end users full rights to the mailbox I want them to be able to receive and send from. The end user is able to receive emails from the other email accounts but when she tries to send as another email address it automatically gives her a undelivarable error.
Any suggestions to resolve this issue are greatly appreciated.
