Office 365: How to add or remove an email alias using Powershell

by 4 Comments

Use the Powershell cmdlet Set-Mailbox to check email aliases assigned to Office 365 accounts, add aliases or remove aliases. Additionally the handy form underneath will generate the correct Powershell commands for you.

Check current email aliases assigned to an Office 365 account:

Get-Mailbox mailboxName | select -ExpandProperty emailaddresses | Select-String -Pattern "smtp"

Add an email alias to an Office 365 account:

Set-Mailbox mailboxName -EmailAddresses @{Add='[email protected]'}

Remove an email alias from an Office 365 account:

Set-Mailbox MailboxName -EmailAddresses @{Remove=’[email protected]’}

Or you can just use the form below and the required Powershell will be generated for you….

Now that you have got multiple email aliases, here is how to configure Outloook so that you can send from an alias.

    I would just like to know how you built this input/output area for the commands on this page. I want to create something like this on my SharePoint site for quick reference and deployment. If you could communicate directly via email that would be greatly appreciated.

    The recipe is missing something, maybe it’s obvious for people used to PowerShell but it was not for me; For this to work I had to do this first, in the PS prompt:

    Install-Module MSOnline
    Import-Module MSOnline

  1. […] The idea behind this method is to setup a second account in Outlook that will enable us to send from an alias that has been defined in Office 365 for a user. It would really be better if the ability to send from an alias was native to Outlook/Office 365, but it isn’t. See these instructions for how to add an alias with Powershell. […]
