1. Ask relevant personnel: directly consult the IT department, human resources department or administrator of your organization or company, and they can usually provide relevant information.
2. Check the company directory or employee list: Many organizations maintain an employee list or company directory, which contains the contact information of each employee, including the email address.
3. Log in to the office mailbox: If you have access to the mailbox, you can try to log in to the office mailbox with the provided user name and password. After logging in, you will be able to check the mail and contact information in your mailbox and determine the owner.
4. Send a test email: If you already know the address of the office email, but you are not sure who it belongs to, you can try to send a test email and ask who the recipient is. Introduce yourself briefly in the email and ask for a reply to confirm the identity of the recipient.
Please note that it is very important to respect privacy and company policies. When obtaining other people's email information, you must have legitimate reasons and abide by relevant laws and regulations.
