Final answer:
To investigate a missing email, an administrator can check the mailbox settings, spam folder, email server logs, and contact the sender for confirmation.
Step-by-step explanation:
To investigate the issue of the missing email, as an administrator, you can follow these steps:
- Check the user's mailbox settings to ensure that emails from external senders are not being automatically filtered or blocked.
- Check the user's spam or junk folder to see if the email was mistakenly marked as spam.
- Review the organization's email server logs to verify if the email was received and delivered to the user's mailbox. This can help identify any potential issues or delays.
- If necessary, you can contact the external person who sent the email to confirm if it was successfully sent and to verify the email address used.
By following these steps, you can gather more information to determine what happened to the missing email.
