Using New Outlook on Windows for professional communication and productivity
Hi Nina,
Welcome to the Microsoft Q&A forum.
Based on your description, you would like to send an email to multiple recipients at the same time without allowing them to see the email addresses of the other recipients.
You can use the Bcc field to do this:
- Click Mail > New Mail.
- In the email compose window, click Bcc.
- In the Bcc field, enter or select the email addresses of the people you want to send the email to.
- After the email is sent, recipients added to the Bcc field will not be able to see the email addresses of the other recipients in the Bcc field.
You can refer to the following document for more information:
Show, hide, and view the Bcc (blind carbon copy) field in Outlook for Windows | Microsoft Support
I hope this information is helpful.
If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
I look forward to continuing the conversation.
