How to Add an Alias to a Mailbox in O365

A mailbox is assigned to an email address associated with a user. Often, a mailbox needs additional email addresses to serve a business purpose, such as receiving the results of survey, customer feedback, or support requests. This allows you to provide contact information to the general public such as “for more information, contact us at info@techsupportnew.com,” without exposing an user’s actual email address. This task shows you how to add an alternate email address to a user’s mailbox.

1.      Go to the Recipients page, click Mailboxes.

2.      Double-click John Snow

3.      In the John Snow form, click email address and then click Add.

4.      In the new email address webpage dialog box, in the Email address type, select SMTP

5.      Now type the alias email address as support@yourdomain.onmicrosoft.com

6.      Note support@yourdomain.onmicrosoft.com is now listed for John Snow under e-mail addresses. Click Save.
