How to Send As a Shared Mailbox

You may be a member of a shared mailbox in Outlook.  It is possible to send messages as a shared mailbox, so that emails will appear to come from the shared mailbox name instead of your personal name.

If you are interested in setting this up because you do not yet have this access, contact the Service Desk.

If you already have this access assigned, follow the steps below to configure this in Outlook.

In a new email in Outlook, select the "From" button above the "To" field.  (If you do not see the "From" button, go to the Options tab at the top of the window and enable the "From" button under the "Show Fields" section.)

In the "From" dropdown, click Other Email Address.

On the next screen, do NOT manually type in the shared mailbox's email address.  If you add it that way, it will not let you send messages as the shared mailbox.

Instead, click the "From..." button and then search for the shared mailbox in the Global Address List.  

When found, click to highlight the row then click OK at the bottom of the window.

Click OK again to add it to your list of Send As options.  To verify it has been added, click the From dropdown again and you should see it listed.

At this point, you can click the shared mailbox address and send an email as the shared mailbox.

If you want to switch back to sending emails as your personal address, click the From dropdown and select your personal email address.
