A. You can grant users a "send on behalf of " ability so that the receiver of a message will see the message is from <sender> on behalf of the person who wanted the message sent. Alternatively, you can give users a true "Send As" ability, in which the recipient will think the message came from the mailbox owner rather than the person who actually sent the message. To grant true Send As functionality, perform these steps:
- Start the Exchange version of Active Directory Users and Computers (Start, Programs, Microsoft Exchange, Active Directory Users and Computers).
- From the View menu, select Advanced Features.
- Right-click the user who wants to let other people send messages on his or her behalf and select Properties.
- Select the Security tab.
- Click Advanced.
- Select the Permissions tab and click Add.
- Enter the users who require the Send As permission, then click OK.
- The list of permissions will be displayed. Ensure "This object only" is selected for the "Apply onto:" field, then scroll to the bottom and select the Send As permission, as the figureshows. Click OK.
- Click OK to the Advanced security dialog box, and click OK to the User Properties window.
The sender of the message now needs to enable the From option in the sending email (Options, From), as the figureshows. Then enter the person from whom the message should come from. The message will appear to the recipient as if it was sent from that person directly. For the From field, make sure you select the name from the address list rather than typing in the name. I've seen problems occur when I type in the name of the sender. If you're using Microsoft Outlook in Cached Exchange Mode, you might also need to force a download of the Offline Address Book (OAB) to see any changes you've made (Tools, Send/Receive, Download Address Book).
