Hello Team,
The error is in Spanish so I had to translate it into English, but I know what this error is all about.
You do not have a valid Outlook 365 connection in your Power Automate environment to use this connector.
Here is what you need to do-
Navigate to your Power Automate environment and inside Data-> Connections

Once over there, click on "+ New connection"

On the page that opens up, navigate to and find O365 Outlook and once you find it click on the + sign in the right corner to add the connection

Once the connection is added, use this connection in your Flow and everything should work just fine for you.
