How to Disable Desktop Alerts in Outlook for Office 365

When I am working at my computer, it’s pretty common for me to have a few different programs open all the time. One of those programs is Outlook, as I need to read and send emails at various points throughout the day.

Since you may not always have Outlook open as the primary window, it can utilize a couple of different methods to let you know when you’ve received a new email message. One of these methods is a desktop alert, where a small window will appear at the bottom-right corner of the window. Some people find this to be helpful, while others find it to be annoyance. If you fall into the latter category, then you can follow the steps below to disable those Outlook desktop alerts.
