How To SEND an email AS\FROM (on behalf of) another mailbox

To send FROM an CRDF department or Team’s mailbox, please follow the steps below:

Open a new email and go to Options,
Click From to show the From field,
Click From > Other E-mail address. Type in the address of the “MailboxName@crdfglobal.org” mailbox or select it from the Global Address book and click OK.

Please note:

The mailbox address may not be visible on the address book yet as the address book gets updated overnight. But if you type it manually, Outlook will find it.
After you send the first email:
1. The FROM option will be there for you so you will not need step 2 again.
2. The mailbox address will be listed under your FROM field. So you won’t need to look for it again (step 3).
