As O365 uses SSO across Exchange, Yammer, Calendar, so on.. it iwuld be great if a centralised notification system was built out and updates in any of these individual systems are pushed out through Notifications.
e.g if i'm logged into Outlook, or skype, i should still receive a notification that originated in Yammer. So a Notification Hub that is common across all of your products. It is how Iphone, windows phone or android notifications work, all the apps in the ecosystem push to a hub and the user has options in settings to manage preferences.

The notifications "bell" in the upper-right seems to consolidate some services, but not others, and, of course, only works if you have a browser open to O365. What's needed is a consolidated notification function that works in all desktop/mobile apps as well as the browser, and covers Exchange, Teams, Yammer, SPO, etc.--anything that can alert or notify.
