ChooseFrom for Exchange Online/Office 365

Purpose

Office 365 mailbox may have multiple SMTP addresses. For outgoing messages Exchange online service always uses the primary SMTP address. For example, John Doe has a mailbox with john.doe@companya.com primary SMTP address and john.doe@companyb.com secondary smtp address. John Doe can easily receive the message addressed both to john.doe@companya.com and john.doe@companyb.com, but he cannot send the message as john.doe@companyb.com because Exchange online rewrites the From address to default one.
ChooseFrom application allows Office 365 users to send an email message (or a meeting request or a task request) with any of their own SMTP addresses as the From address.
The application is a cloud service.

Current version: 1.0.0.1
