Learn how to use the BCC feature in Outlook. We’ll walk you through the steps to add BCC in Outlook for both mobile and desktop. You will also learn what happens when you use BCC in Outlook.
What Does BCC in Email Mean?
BCC stands for “Blind Carbon Copy”. The main difference, compared to carbon copy (CC) emails, is that while other recipients can see a CC’d person’s email address, they cannot see the email addresses of BCC’d users.
BCC is a useful feature to use if you want to email multiple people but still make it look personalized. For example, you may wish to send a company-wide email at your job but do not want dozens (or hundreds) of recipients to appear in the list of CC’d recipients.

You may also want to add BCC in Outlook (and any other email providers you use) if you’d like other people’s email addresses to remain private. This situation may arise if you’re sending messages to multiple friends who aren’t part of the same friendship group, for example.
Another possible scenario when this could occur is if you want to make a big announcement (e.g., an engagement party). If you mainly use Outlook for work, make sure that you don’t make thesecommon mistakes to avoid in your work emails.
