After looking at the costs of having someone else host my email or me getting a VPS and running it there I chose the latter. With 10+ mailboxes I could not find anyone who beat the price of a decent VPS at OVH and run iRedmail compared to O365, Mailbox.org etc. Feels liberating to move off Exchange for good.
@arh I've worked with Exchange server, Kerio Connect, Zimbra, and some others. Yes there are more features in some them compared to iRedmail but the latter has what I need and that's all I can ask for.
