Fix 1: Keep Outlook Open in the Background

Unlike the default Mail app on Mac, you can’t receive new emails on Outlook in the background. You must open the app to get new messages. You can launch Outlook at startup on Mac and check your new emails before starting work hours.

Step 1: Open Settings > General > Login Items.

Step 2: Select > click Outlook from the Applications window.

Step 3: After selecting Microsoft Outlook > click on Open at the bottom-right corner, and you are good to go.

Step 4: Select Microsoft Outlook from the Processes section in the Activity Monitor window and hit X at the top.

Fix 2: Remove and Add an Email Account

Did you recently change your Google or Microsoft account password? Until you re-authenticate your Gmail and Outlook account with new login details, you won’t receive new emails in Outlook on Mac.

Usually, Outlook asks you to enter a new password when it detects old login info. If it doesn’t, remove the current email account and enter it again. Here’s how.

Step 1: Open the Outlook app on your Mac > select Outlook at the top-left corner > choose Settings.

Step 2: Select Accounts from the Outlook Preferences window.

Step 3: Select the account from which you are not receiving emails.

Step 4: Click Minus at the bottom > select Plus > click New Account.

Step 5: Enter your email address and password to sync it again with Outlook.
