Enable the 'Do Not Deliver Before' option to OWA to delay sending emails.
With so many of us working from remote locations and working modified schedules, it is important that we are able to delay email delivery to ensure our colleagues are able to maintain work/life balance, even though some of us may not be able to. With limited VPN resources, I rely on OWA. It would be nice to have the functionality of delayed delivery in OWA, like I do in the desktop app.
There exists an add-in that allows you to delay email sending in Office 365 OWA:
Or at least have Outlook store this option on the server, not on my computer, so that the email can be delivered at the requested time even if MY computer is not on.
