+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. Valid values are:
 
-- $true: Users in Outlook on the web get an option to send messages and reply to messages with a proxy addresses.
-- $false: Users can only send messages and reply to messages using their primary email address. This is the default value.
+- $true: Aliases on messages will no longer be rewritten to their Primary SMTP addresses. Compatible Outlook clients will allow sending from aliases and replying to aliases.
+- $false: Aliases on messages sent or received will be rewritten to their primary email address. This is the default value.
