Question

my emails intermittently not receiving emails sent to me.

Answer 1

I am sending emails at people at different businesses and getting bouncebacks. Is there an outage?

Answer 2

If you are intermittently not receiving emails, there could be several reasons for this issue. Here are some common causes and troubleshooting steps you can consider:

1. Email Server Issues: The email server may be down or unreachable, which can affect email delivery.
2. Spam Filters: Check your spam or junk folder to see if the emails are being filtered there.
3. Email Quarantine: If you are using a spam filter solution, emails may be quarantined. Ensure that your email domain is properly configured in your SPF record and check the allow list settings of your spam filter.
4. Network Issues: Ensure your network allows connections from the IP addresses used by Microsoft 365 datacenters.
5. Throttling: If there is suspicious activity from your IP address, Microsoft 365 may temporarily restrict mail from that source.
6. Permissions: Ensure you have the necessary permissions to receive emails from specific senders.

If the problem persists, you may want to contact your email administrator or support for further assistance.
