Outlook email not received – troubleshooting steps for Microsoft users

If Outlook fails to receive messages, first verify that the mailbox works via Outlook on the web. When messages arrive in the browser but not in the desktop client, the issue is usually local synchronization or account configuration. Check available storage space in the Microsoft account settings, as a full mailbox can halt delivery. Review the Junk Email folder, other filtered sections, and any custom rules that might move or delete incoming mail. Ensure no senders are blocked, and temporarily disable rules that forward or delete messages. After confirming storage and filters, re‑sync the account or recreate the Outlook profile if needed, taking care to back up passwords and data before any profile removal.
