Hi @Harry
Thank you for reaching out to Microsoft Learn Q&A!
Based on your description, I understand how inconvenient it can be when you're unable to receive emails. I'm here to work alongside you to find a solution and resolve this issue using all the resources available to me.
To help trace the path of the missing emails, there's an efficient tool in the Exchange Admin Center called Message Trace. It allows you to track how and where the emails were sent, from the source to your mailbox. You can refer to this article for more details: Message trace in the new EAC in Exchange Online | Microsoft Learn
If the Message Trace doesn't provide helpful insights and the issue persists, may I ask some clarifying questions?
Question 1: Does the issue occur on a specific Outlook platform (e.g., Outlook on the web, desktop app, or mobile app), or is it happening across all platforms?
Question 2: Have you checked if there are any inbox rules that might be affecting email delivery?
Question 3: Are you using any add-ins or third-party tools that could interfere with receiving emails?
Any updates, additional context, or follow-up questions you provide enable us to refine our guidance and offer more accurate support; not only for you, but for others in the community who may be experiencing similar issues.
