Sending emails from mailboxes added to Outlook

Posted on 2007-10-20

If a user has been given another user's mailbox in their own Oulook (i.e. mail box added, so it opens when their own outlook opens), how do they then also send emails from this mailbox.

They have been given mailbox rights, but is there a permission that lets them send mail. If so where is it?

    ...ooops forgot the main part.

    Is it just the granting permissions that lets the "user send on behalf of" that we need.

    If not what is it?

    ok , just create new message and then press accounts botton over TO: field, then select the 2user account and send the message the message will send using the 2user account.

    On Exchange 2003, for a user to be able to send email as someone else while the mailbox is open in Outlook, they need two permissions...

    1. Full Mailbox Access. This allows them to open the mailbox. It used to also grant "Send As" permission, but this has now been removed.

    2. "Send as" or "Send on Behalf" permissions. You need to set one of these. They are different and you cannot set both.
    "Send on Behalf" sets the header to say "User 1 on behalf of User 2" and therefore makes it clear the message was sent by someone else. This is set on the Exchange General, Delivery Options.
    "Send As" allows the message to come from the user without any reference to the actual sender. This is set on the Security tab. If you cannot see the Security tab then close the properties of the user and then choose View, Advanced Features in ADUC.

    In both cases you will use the "From" field to control which account the messages comes "from".

    @ Simon: If I do it the "Send As" way. Do I only grant the Send As and Receive As.

    The rest are not needed, right?

    Send As/Receive As works. The key point is that Full mailbox no longer grants send as, so you have to grant that permission whatever happens.
