There is no way to print an email message directly within Outlook that shows recipients included in the Bcc (blind carbon copy) field. However, you can use a screen capture program to capture an image of the email and then print that image.

In Windows 10, the Windows Snipping Tool is an easy-to-use screen capture method. To open the Windows Snipping Tool, select the Windows key, then start typing the word snipping. Once you see the Snipping Tool appear on the Start menu, select it.

With the Snipping Tool open, use the following steps to capture an image of your sent email with Bcc information included.
