We are excited to announce another highly requested feature on our consumer as well as business UserVoice forums is now available: Send Later! This feature requires Office 365 Subscription and will be available in Insider Fast update 15.35.170509 rolling out today.

This feature requires Exchange 2016 CU5+ / Office 365 / email accounts. Please note, your account has to be on the Office 365 backend (see announcement).

How does it work?

The first email you compose on the new build introduces the feature with a callout:

The message is saved to Drafts folder – icon on message list shows it’s to be sent later and infobar in Preview Pane shows the time it will be sent with an option to Cancel Send. Note: Once scheduled Outlook does not need to be open to send the message at later time.
