Being able to assign sensitivity labels through Office 365 means nothing except that the steps to enable sensitivity labels within your tenant have been taken. We’re dealing with a different app here (your app) and it’s that app must must be authorized to use the assignSensitivityLabels API.

The app that you’re using must be associated with an Azure subscription so that you can pay to use the API. If this isn’t done, the API won’t work. Something is obviously missing in the setup that you’re using. As I can’t see your setup, I can’t be much more help than to say you should check every aspect of the setup you’re using (app, permissions, subscription, API call) to be 100% positive that something small is not amiss.

And the app you are using to assign sensitivity labels is associated with an Azure subscription? You can’t assign sensitivity labels with delegated permissions.

Never had a problem with standard Word documents… I assume you can apply a sensitivity labels to these files by opening them in Word?

Standard docx files…
Thanks for the response 🙂

Nope. Haven’t seen that one before. What type of file are you processing?

I’ve run into an issue with the assignSensitivityLabel API. I’m getting this error:
{
“error”: {
“code”: “notSupported”,
“message”: “Sensitivity label cannot be assigned due to unsupported feature.”,
“innerError”: {
“code”: “unprocessableEntity”
}
}
}
Any idea what might be causing this? Have you seen it before?

Thanks!
