Office 365 : Tasks with Email


  • This article will show the common Email tasks in Office 365

1. Add another alias email to the user

The primary email address in Office 365 is usually the email address the user specified when their Office 365 was created. When a user sends an email to others, their primary email address is the one that usually appears in the From section of the email application. They may also have multiple email addresses associated with their Office 365 for business accounts. These additional addresses are called aliases.

For example, suppose that Micheal has an email address, but she also wants to receive emails at because some people call her by that name. You can create alias for her so that both email addresses are in Micheal’s inbox.

You must have admin rights to do this.

  • In the Admin Center, visit the Active users page or select Users > Active users.
  • On the Active Users page, select the name of the person you want to edit.
  • On the right, in the Username / Email Aliases Email row, choose Edit.
  • Note: If you get the error message “A parameter cannot be found that matches parameter name ‘EmailAddresses,” it means that it will take a bit longer to complete your tenant setup or custom domain name if you have added recently. The setup process may take up to 4 hours to complete. Wait for a while for the setup process to finish, then try again. If the problem persists, call Support and they will perform a full synchronization for you.
  • On the Edit email addresses page, in the text box below Alias, enter the first part of the new email alias. If you have added your own domain name to Office 365, you can choose a domain name for the new email alias using the drop-down list. Then select Add.
  • When you’re done, select Save.
  • Wait 24 hours for new aliases to appear throughout Office 365.
  • The user currently has a primary address and alias. All mail sent to and will go to Eliza’s Inbox.
