Introduction #
One of the most long awaited and requested features in Exchange Online is the ability to send from an alias (proxy) address. Until recently (roadmap) (roadmap), it’s only been possible to receive email using an alias. There are many use cases for this feature, which in it’s absence, has required the use of additional mailboxes, typically user or shared mailboxes, as an alternative approach. For example, when a company has multiple domain names and a user is required to send and receive email from each.
With send as alias enabled, administrators can avoid the overhead of creating additional mailboxes when a user needs to send and receive from an email address other than their primary address. Additional mailboxes incur admin overhead, require support to configure in Outlook and create additional requests for helpdesk when setting up new users. With send as alias enabled, administrators can reduce the support overhead and achieve a better experience for their end users.
By default, send from alias is disabled and administrators must enable it to use the feature. We recommend enabling this feature for all tenants to create a consistent experience for your customers.
This MSPMagic setting allows you to configure send from alias to be either enabled (recommended) or disabled.
User Impact #
Low – Enabling send from alias has little to no user impact.
Parameters #
Enabled – True/False
Admin Portal Reference #
Not available in admin portal
PowerShell Reference #
To enable
Set-OrganizationConfig -SendFromAliasEnabled $true
To disable
Set-OrganizationConfig -SendFromAliasEnabled $false
The SendFromAliasEnabled parameter allows mailbox users to send messages using aliases (proxy addresses). It does this by disabling the rewriting of aliases to their primary SMTP address. This change is implemented in the Exchange Online service. At the same time, Outlook clients are making changes to natively support aliases for sending and receiving messages. Even without an updated client, changes in behavior may be seen for users using any email client as the setting affects all messages sent and received by a mailbox.
