If Outlook is not receiving emails then firstly make sure that you have an active internet connection. It is quite possible that Outlook’s service might be down. All you need to do is go to Outlook’s Service Status page and check its current status. If it is marked red, then it means that Outlook is not available at the moment.
If your inbox is full and does not have enough free space then Outlook would not receive emails. In order to fix this, you can just go to the Junk Folder or any other folder and delete all the unwanted emails. You can also try the Sweep feature on Outlook which would delete old emails from a sender automatically.
If you have added a particular user to the block list then you won’t be able to receive an email from them. Sometimes, we add someone to the block list and forget it later. To fix it, just go to Outlook’s Settings, then Mail and select Junk email. This will display a list of all the email ids that you have blocked. Just click on the delete button to remove them from your block list and you will be able to receive emails. Feel free to get in touch with us and we will be happy to assist you.
