Microsoft is rolling out a much-anticipated feature that lets users send emails from their own aliases. Traditionally, to be able to send from another email address, that address had to be set up as another licensed account or shared mailbox at the least.  

Thankfully, that is now changing. Once the feature is enabled in your Microsoft 365 tenant, users can start sending out as aliases that have been configured on their accounts. We have found this most useful when multiple domains/companies are configured in the same tenant. So instead of having multiple mailboxes for a user to manage & organize, they can maintain everything in one account.  

Administrative Steps 

  1. From PowerShell:
    • Connect-Exchange Online
    • Set Organization Config -SendFromAliasEnabled $true 
  2. From Microsoft 365 Admin Center 
    • Select user account 
    • Under Aliases -> Click Manage username and email
    • Add desired email alias as needed email alias

End-user Steps 

  1. Enable From button 
    • Start new email
    • Click the Options tab in the ribbon
    • Click Fromhow to add email as alias
  2. The From button now appears in new emails 
    • Click this new From button -> Click Other email address 
    • Manually type in an email alias that was added to the account -> Click OKemail alias
    • After the first message is successfully sent, the alias will be available to select from the From dropdown menu for quick access. Microst 365 email alias
