Our team has been struggling with a frustrating email syncing issue in the 'New' Outlook for the past six months. While the inbox shows an alert for new emails, the actual emails don't appear unless users click in and out of the inbox folder. This has caused some staff to miss important emails. Although we've advised everyone to revert to classic Outlook for now, we want to provide the option to use either version. Since this problem persists even after re-imaging devices and affects all staff members, we suspect it's not isolated to just one setup. We've also tried running the app in the background and disabling offline mode. Has anyone else experienced this, or do you have any solutions?

That sounds really strange! I haven't experienced this with any of my clients using the new Outlook. Maybe there's a setting preventing the inbox from refreshing automatically? Do you have any complicated configurations set up in Microsoft Edge? Also, does the issue show up in the Outlook Web App?
Honestly, I would just block New Outlook altogether and stick with Classic for now until they make some serious upgrades. It's only a matter of time before they phase it out anyway.
I've heard New Outlook still has quite a few missing features, which is why I can't let my clients use it yet. I hadn't come across this specific issue, but I appreciate you bringing it up as it helps me prepare for potential problems in the future.
I haven't faced that issue exactly, but I've noticed other syncing problems, particularly with folders. It's weird because in the Outlook Web App, folder changes sync quickly, while the New Outlook takes ages or doesn't refresh at all unless restarted when I move or create folders in Classic Outlook. It's like it’s lagging behind for no reason.

This is what you get from the biggest software company in the world. Even when they release questionable software, people still flock to buy it.
