Use BCC to Avoid Reply-All


The Help Desk suggests using the BCC field to ensure no one accidentally does a ‘Reply All’ to messages sent to distribution lists.

Enter the distribution list’s address in the BCC field instead of the TO field or your email.  Then, even if someone accidentally, or purposely, clicks the “Reply All” button, the message will only go the original message’s sender.  It’s an easy and foolproof way to stop the dreaded “Reply All”.
