Not getting emails from within organization

Question

I am not receiving any emails from the 3 people within my organization. I am receiving emails regularly. I even receive the replies to emails sent to people outside my organization from persons within my organization. (Anita is a co-worker who cc's me on all outgoing emails. I do not receive these emails from Anita in my inbox, but I do receive the replies to these emails in my inbox). All 3 other persons in my organization (domain) have tried to send emails directly to me. I have not received these emails in my inbox, junk/spam, deleted.

Has anyone had this issue?

Hi @Shela Morton,

Thank you for posting your question in the Microsoft Q&A forum and for clearly describing the behavior you’re experiencing, that level of detail is very helpful.

I understand how confusing and disruptive this can be, especially when you’re able to receive emails from outside your organization and replies from internal users, but not the original emails sent directly from coworkers within your domain. Based on what you’ve shared, this type of behavior typically points to a mail flow, rule, or mailbox‑level setting, rather than a general Outlook app issue.

To help narrow this down, I recommend going through the steps below in order, as each one checks a different possible cause that is common with New Outlook for Windows:

1/ Review rules in New Outlook (including unexpected or hidden behavior):

First, please check your rules in New Outlook to ensure that messages from your internal domain are not being automatically moved, redirected, or deleted.

• In New Outlook, go to Settings > Mail > Rules.
  
• Temporarily disable any rules you see, then ask one of your coworkers to send a test email.

Even a rule that looks harmless can sometimes behave unexpectedly, so disabling them briefly helps rule this out.

2/ Check Focused Inbox and other folders:

Next, please confirm that the missing emails are not being filtered into Other, Archive, or another folder.

In New Outlook, Focused Inbox filtering can sometimes make emails appear missing, even though they are being delivered successfully. If you’re using Focused Inbox, please check both Focused and Other tabs carefully.

3/ Confirm delivery status with an internal sender:

Since the emails from your coworkers never appear in any folder, it would be helpful if one of them could confirm whether their message shows as successfully sent or delivered on their side.

If the message does not reach your mailbox at all, this usually indicates a server‑side or tenant‑level issue, rather than something specific to your Outlook app.

Additionally, try sign in to Outlook on the web (OWA) and have one coworker send a fresh test email to you, If it appears in OWA but not in new Outlook, then it’s likely a client/sync/view issue.

4/ Involve your IT administrator to check mailbox and mail flow settings:

At this point, it’s important to involve your IT administrator. Issues where only internal emails are affected are often caused by:

• Mail flow (transport) rules.
• Internal domain filtering.
• Mailbox‑level restrictions or policies.

These settings are managed at the organizational level and cannot be viewed or changed from New Outlook itself.

Your IT administrator can review more details here:

• Mail flow rules (transport rules) in Exchange Online.
• Quarantined email messages in cloud organizations.
• Frequently asked questions - Quarantined messages.
• Apply or remove mailbox policies for Outlook on the web and the new Outlook for Windows in Exchange Online.

5/ Contact Microsoft Support through your admin:

If your IT administrator confirms that everything looks correct but the issue continues, they can open a support case with Microsoft by sign in to the Microsoft 365 Admin Center following steps from this link: Get support - Microsoft 365 admin | Microsoft Learn to raise a support ticket from admin center or calling the phone support to contact Microsoft Support: Customer service phone numbers - Microsoft Support to perform deeper mail flow and mailbox diagnostics. If you don't have admin privileges, you can ask your IT administrator to create it on your behalf.

Alternatively, you can look for the way to find your admin through this link: How do I find my Microsoft 365 admin? - Microsoft Support.
