I've noticed there seems to be differences in how the delayed send feature is described/supported in the various Outlook apps. OWA doesn't seem to support it at all, Outlook for Windows desktop supports it but only if the app is open and online at the time the email is scheduled to send, and Outlook for Mac supports delayed sending even when the app isn't online (not sure about Outlook UWP or the mobile apps). Is there any goal to eventually make this feature consistent across clients?
