How to Reply and Forward in Outlook
Rather than creating a new email to respond to an email you’ve received, you can just reply to the original email to continue the email chain, or conversation.
Here’s how to reply to an email.
If a message includes an attachment, the attachment will not be included with the reply, as it was the same person who sent you the attachment in the first place.
You can also forward emails you receive to someone who wasn’t an original recipient.
If the original message includes an attachment, the attachment will also be included in the forward.
