Hi, I'm John! I will help you with this.
To help narrow down the issue:
- May I know what troubleshooting steps have you already taken? This will help me avoid recommending them again.
- Also are you using personal Microsoft account or work or school account?
In the meantime if you haven’t already:
I recommend checking out this Microsoft support article: "Can't send or receive email in Outlook.com" https://support.microsoft.com/office/can-t-send-or-receive-email-in-outlook-com-d39e3341-8d79-4bf1-b3c7-ded602233642
- Please scroll down and take a look at the sections titled "Can’t send mail in Outlook.com" and "Can’t receive mail in Outlook.com".
- It walks you through some helpful steps that usually resolve this kind of issue.
- Make sure your Focused Inbox is turned off, so all messages show in one place.
- Check your mailbox settings to confirm nothing is filtering or blocking those emails.
Let me know how it goes or if you have any further questions or concerns.
