Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Is this happening on one device or on all your devices?
- Have you checked if Focused Inbox is turned on and if your emails might be going to the Other tab instead of the main Inbox?
In the meantime, 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 receive mail in Outlook.com". It walks you through some helpful steps that usually resolve this kind of issue.
- Check your mailbox settings to confirm nothing is filtering or blocking those emails.
- Make sure your Focused Inbox is turned off, so all messages show in one place. https://support.microsoft.com/office/focused-inbox-for-outlook-f445ad7f-02f4-4294-a82e-71d8964e3978
- Try adding their email addresses to your Safe Senders list to make sure Outlook doesn’t block or redirect them. https://support.microsoft.com/office/add-recipients-to-the-safe-senders-list-in-outlook-be1baea0-beab-4a30-b968-9004332336ce
Check any Outlook rules:
- In https://outlook.live.com/mail go to Settings > View all Outlook settings > Mail > Rules and Mail > Forwarding to make sure no one has set up rules to forward or delete your messages.
If the issue persists, please provide more details by answering my questions.
