An Office 365 mailbox may have multiple SMTP addresses. For outgoing messages, the Exchange Online service always uses the primary SMTP address. For example, John Doe has a mailbox with email@example.com primary SMTP address and firstname.lastname@example.org secondary smtp address. John Doe can easily receive the message addressed both to email@example.com and firstname.lastname@example.org, but he can not send the message as email@example.com because Exchange online rewrites the From address to default one.
The ChooseFrom 365 application allows Office 365 users to send a message with any of their own SMTP addresses as the From address.
The application is a cloud service.
- You do not need to create an additional “fake” mailbox or contact specifically for storing an additional From address.
- The application is server-centric, so you do not need to install any extra software on the client side.
