How to show the task pane in the Office add-in for Outlook?
I'm using Visual Studio 2019 to develop an Office add-in for Outlook. I would like to see the Office Add-in task pane when composing a new message.
Using event-based activation, I can fire an event when a new message is created, but I don't know how to show the task pane.
The site below calls the Office.addin.showAsTaskpane() method to show the task pane, but it requires the use of a shared runtime and does not support Outlook.
Are there other ways to show the Office Add-ins task pane in Outlook?
