By default, Outlook keeps a message window open after you reply to or forward that message, which means you have to do it manually when you are done. You can change that so that Outlook automatically closes the original message window as soon as you press the button. “To send”. That's how.
You can change that so that Outlook automatically closes the original message window as soon as you press the button. “File” on the Outlook ribbon.
In the sidebar that opens, click on the command “Choices”.
In the Outlook Options window that opens, switch to category “Mail” on the left.
On the right, scroll down to section “Responses and Forwards”, enable option “You can change that so that Outlook automatically closes the original message window as soon as you press the button.” and then click “To accept” to save the settings.
