It used to be that when you want to send an email using a specific email address, that email address must be the primary and not one of the aliases. So if a user needs to send a message from different email addresses, the typical solution is to have a Send As permission on other mailboxes.
But now, Exchange Online allows users to send messages using their Exchange alias addresses. And we’ll show you how to enable this feature and use it.
Enable Sending Messages from the Exchange Alias Address
The setting for sending from an Exchange alias address is disabled by default. But enabling this setting isn’t complicated and can be done in a few steps. But remember that this setting change is global to the Exchange Online organization, meaning you must be assigned the Exchange Administrator role or be a member of the Organization Management group.
Method 1: Using the Exchange Admin Center
Enabling sending from aliases using the EAC is a straightforward process that any administrator with sufficient permission can perform.
Log in to the Exchange Admin Center and navigate to Settings > Mail flow.
On the fly-out, enable the Turn on sending from aliases check box and click Save.
And you will see a confirmation banner like the one below, confirming the setting has been saved.
Method 2: Using the Exchange Online PowerShell
Another way to turn on sending from the Microsoft Exchange alias email address is through the Exchange Online PowerShell.
First, connect to the Exchange Online PowerShell session.
Note. Check our post on how to set up an email disclaimer in Microsoft 365.
Run the command below to switch on the Exchange send email from alias setting in the organization configuration. The -Verbose switch is optional and used only to display verbose messages.
Set-OrganizationConfig -SendFromAliasEnabled $True -Verbose
For good measure, let’s confirm that the setting was saved by running this command.
Get-OrganizationConfig | Select-Object SendFromAliasEnabled
As you can see below, the SendFromAliasEnabled value is True, which means the Exchange send email from alias setting is enabled.
Send Email from an Exchange Alias Email Address
Now that the sending from alias setting is enabled, how can the users take advantage of this feature? First, they must have one or more email aliases to use. If not, you must add an alias to Exchange Mailbox first.
Using Outlook on the Web
Log in to Outlook on the Web.
Next, open Outlook Settings and navigate to Mail > Compose and reply.
The email aliases list is under the Addresses to send from section. Check all the email aliases the user wants to use as the sender address and click Save.
Click New mail.
Click the From button to list all available email aliases and click the one to use as the sender.
The From address changes, and the user can now send an email using this email alias.
Using Outlook Desktop Client
Open Outlook and click New Email.
Switch to the Options tab and click From to show the From field. Click the From field and Manage List.
Check the email aliases to enable and click OK.
Click the From button, and the user can select the email alias to use as the sender address.
The From address changes, and the user can now use it as the sender.
Email aliases provide a simple and effective way to manage multiple email addresses using a single email account. In Exchange Online, setting up email aliases is a straightforward process that can be completed by following a few simple steps.
Email aliases can enhance your email communication, improve your branding, and simplify your email management. Whether you are a business owner, a professional, or an individual user, using email aliases in Exchange Online can be a valuable tool to help you stay organized and productive.
