There are a few common reasons why Outlook might not be receiving emails. Here are some of the most common causes and how to fix them:
Incorrect email settings. Make sure that you have entered the correct email address, password, and server settings for your account. You can find these settings in your email provider's help documentation.
Account is offline. Make sure that your Outlook account is set to online. You can do this by going to File > Account Settings > Account Settings and selecting the account that is not receiving emails. Under Account Status, make sure that the Status is set to Online.
Firewall or antivirus blocking emails. Your firewall or antivirus software may be blocking emails from your email provider. Make sure that your firewall or antivirus software is configured to allow emails from your email provider.
Corrupted profile. Your Outlook profile may be corrupted. You can try creating a new Outlook profile to see if that fixes the problem. To create a new Outlook profile, go to File > Account Settings > Account Settings and click on the Add button. Select Manually configure server settings or additional server types and then select Internet E-mail. Enter your email address and password and then click on Next. Select IMAP as the Account Type and then enter the server settings for your email provider. Click on Next and then Finish.
Server issue. There may be a problem with the email server that is hosting your account. You can contact your email provider for assistance.
