Schedule Send

Haven't used Outlook for some time but thought I would take a look at the 'new' Outlook. However, I immediately notice it still doesn't support schedule send of IMAP accounts so still remaining with Gmail.

I don't use it myself, but I believe in New Outlook windows app, only accounts with Exchange protocol can see 'schedule send' option, if you are using non-Microsoft mailbox, or you have set up IMAP, POP protocol for your current mailbox, then you can't see "schedule send' option. At least that's the way it has been from the beginning of outlook new.

I just tried it in my Outlook Classic and I can use tags to set when I want to deliver a message in all my email accounts, both exchange and third party..
