Add "Delay delivery" to outlook.com (web) and mobile apps

This is even more frustrating to me from an email platform I must use professionally than not being able to insert my business's logos and QR codes in my email signature on any Android based Outlook platform, either the app or the web browser version. Not being able to do that, or delay sending emails, is incredibly frustrating. 

Many people don't have an alternate option to Outlook per their employer's network security policies, which I would think Microsoft would be well aware of. The fact the level of support and features available in software that has to be paid for while other email providers such as Gmail have the "delay send" function and are free of cost is truly absurd.

It feels like Microsoft's knowledge that much of the user base for Office 365 are effectively trapped with having to use that software just means they don't care about keeping their platforms and functionality even at the current average standards of competitors, much less trying to create new capabilities for Outlook 365.

Lacking both these functions drastically reduce how professional I'm able to seem in correspondence. What's equally, if not more, frustrating is that many of these features are available for iOS, both in the browser version of Outlook and in the mobile app, and these features have been available for quite some time.
