She hadn’t been at her Mac in a several months (pandemic and all), and now when opening Outlook it would barely even bounce before crashing and popping up an error message that read, But IMAP is a pain to work with, and wasn’t really designed to operate with multiple clients all syncing states are random intervals, so I can understand the desire to abstract all of that complexity away from clients, and have it server side where it’s easy to respond breakages and deploy fixes.The week before, in my day job as an IT technician, I received a request to help a professor with her Microsoft Outlook app. If IMAP was more consistently implemented, and predictable across different mail services, I would be a lot more cynical of Microsoft’s server side sync.

No need to deal with various IMAP idiosyncrasies, and lack of sync/version merging primitives in IMAP. Not to mention iOS generally doesn’t allow apps to poll very frequently, if at all, to keep battery usage to a minimum.īy syncing to a Microsoft server they can originate their own push notifications by have high poll rate server side, allowing for fast delivery of emails to mobile clients, without eating up their batteries.Īdditionally managing email sync state would be much easier via a Microsoft server. Gmail doesn’t provide push over IMAP to non-business accounts, so devices need to poll. Click to expand.Push notifications on iOS would be one use.
