Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
The same issue started for me, and at the same time for my wife, earlier this week. We both get alerts for the new messages along with an alert in the notification area but no new emails show in the inbox. Removing and adding the account back showed the emails but new messages still do not show up.
I logged on to my computer earlier this week and opened the email app, receiving a message that something was upgraded (new emails do show up). I thought my account was upgraded months ago. Maybe the two are not related but the issue with my Android app started on the very same day.
