I noticed I don’t get notifications for incoming emails anymore after upgrading to win8.1,
Sometimes I do, most of the times I don’t.
The guys implemented a new feature into the mail app (not outlook, the native mail app) called “favorites”, and it is adding people you are most commonly communicating with to that list.
The settings by default changed to show the notification only when you get an email from someone from that group, so it does not distract you when you get emails from other people.
If you do want the notification to show all the time you can of course change it, for instance if you work at sales or support I guess most of your emails would not be from a selected few.
But for the most part, this is great in reducing the distraction involved with constantly getting email notifications on my screen. I just wish it was a bit more clear and perhaps even prompted me about this instead of just applying it for me.
You go to your mail app, settings, accounts and this is where you find it!
