If your Outlook desktop app is no longer receiving new email, this could be a problem with your network connection, current password, or you have the Work Offline option selected.
You may have a message like this at the bottom of your Outlook app:
If you have changed your password recently, the Outlook client will no longer be able to retrieve your new email until that password is updated in the client. Once Outlook attempts to retrieve new email, it will prompt you to enter your password.
If you don't want to wait for the app to do this, you may be able to force it to retrieve new mail using the Send/Receive All Folders buttons found either at the top left of your app screen or under the Send/Receive tab.
Also, check to make sure you don't have Work Offline selected
If the issue persists, please check your network connection or contact Technology Support Services using the contact info below.
