I have a SBS 2011 and the customer wants to be able to send email from an email address that is not there own.
They are using Outlook 2007 I set up a separate profile with email@example.com on each of there computers. They exit Outlook and open this new profile. Everything is fine until they go to send an email and they it says they do not have permission to send on behalf of estimates.
I have given everyone Full Access Permissions to this account but they still get that error.
