I wonder why I am still unable to "send as" from my Outlook using this particular mailbox ? eventhough:
1. I was able to open up the Mailbox successfully as additional mailbox in my Outlook
2. Grant my self "FULL ACCESS" and the "Send on Behalf"
do I have to make this mailbox as "Shared mailbox" instead of normal mailbox ?
FYI: I'm using the following:
Exchange Server 2007 SP1
Outlook 2007 SP2
Domain functionality level: Windows Server 2003
Forest functionality level: Windows 2000
and I still don't understand why after recreating the user mailbox and making the configuration the same I still cannot "send on the behalf of" this new user mailbox ?
the previous mailbox is a shared mailbox which was created long time ago since Exchange 2003 and now I have deleted that after exporting all of the mail content.
