Solution 1Recommended

Check Local Mailbox Filters and Junk Folder

Ensure that your local email client settings have not mistakenly filtered the automated email or marked it as spam.

Automated emails are frequently flagged by spam filters because they are sent by system servers rather than individual users. Your mailbox rules might also be redirecting these messages away from your primary inbox.

Check the Junk Folder

Navigate to your Junk Email or Spam folder in your email client. Search for the missing automated email, and if you find it, right-click the message and select 'Not Junk' to prevent future filtering.

Review Inbox Rules

Go to your email account settings and open the 'Rules' or 'Filters' section. Review your active rules to ensure there are no settings automatically moving or deleting messages from unverified senders.

Solution 2

Perform Sender-Side Checks and Admin Message Trace

Determine if the issue originates from the sender's mail server or requires administrator intervention for organizational accounts.

Frequently Asked Questions

Why are automated emails suddenly going to my Junk folder?

Email providers continuously update their security filters. If an automated sender lacks proper email authentication records (such as SPF, DKIM, or DMARC), your email server may flag the message as suspicious and route it directly to the Junk folder.

What is a message trace in Microsoft 365?

A message trace is an administrative diagnostic tool located in the Exchange Admin Center. It tracks email messages as they travel through your organization's server environment, allowing IT administrators to see exactly if an email was received, rejected, deferred, or placed in quarantine.

Can a full mailbox prevent me from receiving automated emails?

Yes. If your mailbox storage has reached its maximum quota limit, all incoming messages—including automatically generated emails—will be immediately rejected by your server, and the sender will typically receive a bounce-back notification.
