Hey, I would like to create a powerapp where an E-Mail is sent when I press a button, but the System tells me that the function is unknown.
Office365Outlook on OnSelect is the function I would like to use.
Is there any new function?
You need to add the data source before you can use the function
So when you click on the Data sources icon on the left, you must see Office365Outlook if that is the data source you are trying to use to send the email
For your ref here is a link to show how to add it:
