Expand Office 365 menu.
You will be presented with the following screen:
- Alternate Addresses
- At a minimum, it will include your primary address. Any additional addresses listed will also be able to receive mail and calendar invitations.
Important: If you do not have any alternate addresses (in addition to your primary address), then you must create an alternate address before you can send a message using your alternate address.
Important: These steps outline the only known method to send messages from an alternate email addresses in Outlook 2016 for Mac. To do so, you will need to configure an additional account for each alternate address you'd like to send from. The additional account(s) will have the same folders and messages as your primary Outlook 2016 for Mac account - the main difference is that it will be configured to use the alternate address. Each account will be listed in Outlook, and every time it checks for new mail the same new messages will be found and delivered for the Exchange account as well as any alternate accounts. These issues are cosmetic and should not impact your Outlook experience.
Launch Outlook 2016 for Mac.
Open the Outlook menu and select preferences.
Click the Accounts icon from the Outlook Preferences window.

Click the Server tab
Check Download headers only
Uncheck Except in Inbox
Uncheck Sync all IMAP folders every 2 minutes
Uncheck Use IMAP IDLE if the server supports it

- Before sending a message, click the From drop-down box and select your alternate address from the list.
When you are ready, click the Send button. When the recipient receives this message, the "From" and "Reply-to" addresses will be the alternate address.
Note: You will now see separate accounts listed for your primary and alternate email addresses, and each account will have the same folders and messages. There is no way to completely hide the alternate account or stop it from checking for new mail, but this should not impact your Outlook experience. Click the small down-arrow next to your alternate account so your folders are only listed once:
