At work, you may come across an incident where you have to send multiple messages and forward to your co-worker. Instead of forwarding multiple messages, combine the messages and send as a single message or attachment.
1. Select multiple messages to send by holding [CTRL].
2. Go to the [Home] tab -> [Respond] group -> click [Forward]. (This will send the messages in the body)
3. To forward as attachment, click on [More] and select [Forward as Attachment].
