In Outlook, how can I send mail from a departmental mailbox? View The Full Article Note: The instructions in this document do not apply to versions of Outlook for Mac OS. In Outlook, it is possible for you to change the From: field of an email message you wish to send, hiding your name and making it appear as if your departmental mailbox is sending the message. To do so, you must first have Send As permissions enabled for your department. If these permissions are not enabled. Send As permissions can only be given to departmental mailboxes. To send mail from your departmental mailbox, follow the steps below: 1. From the File menu, select New, then Mail Message. 2. When the new message window opens, from the View menu, select From Field. If you have Word selected as your editor, click the Options... button and select From. 3. In the new message window, in the From... field, enter the name of your department. Then compose and send your message as you would normally. Once you have added the From: field to a message, it will appear in each new message you create. To disable the From: field, simply repeat the steps above and deselect From Field or From. The sent message will be stored in your Sent Items folder, not in the departmental Sent Items folder. To move the sent message to your departmentand39s Sent Items folder, first open your departmentand39s mailbox in your folder list, then drag the sent message from your Sent Items folder and drop it in your departmentand39s Sent Items folder. You may also set up a rule in Outlook to automatically move sent messages from your Sent Items folder to your departmentand39s Sent Items folder.
