Yesterday Microsoft launched a new app designed for “brief, snappy” communications in Office 365 for Business: Send.

This is a Microsoft Garage app, which means we can think of it as something of a test product–it may change before it is released widely.

With Send, there are no signatures, subject lines or salutations required. Our design principle for the app was to make conversations fast and fluid while keeping the people who are important to you at its core. Send connects to Office 365 business and school email accounts to surface your frequent and recent contacts. The people who are important to you are put right at your fingertips—just tap on a contact to start a conversation. Or even better, simply swipe and choose a Quick Reply such as “On my way” or “I’ll get back to you.” You can also see when someone is typing their response; there’s never been a quicker way to reach someone over email.

More details about Send:

• Send only shows communications initiated from within the application itself, not all your emails.

• However, conversations started in Send will sync with Outlook, letting you continue the conversation there.

• You can message anyone with an email address; no need to have their phone number or username.

• Send connects to Office 365, using Azure AD authentication and Exchange to transport and store messages. It currently has no admin controls, but inherits policies from Exchange.

Send is currently available on iPhone in the US (for Office 365 for Business users), so you can check it out in the app store.
