So as of yet, I know there is no official trigger where when we assign a category to an email message, that Power Automate can perform an action.
In another post, I found part of a workaround which uses the following actions:
- Send an HTTP request (for Outlook); and
- Parse JSON.
I got those to work (see image below), but the following actions, whether I use a Compose action, Variable action or a 'For each', etc., I am getting an error message to say answer type 'NULL', however you will also see as part of the image, part of the RAW Output from the Parse JSON action, that it did pull some information.
I am at a lost...
