Access Token Validation Failure

[itsmeqp]

I have a user is having issues using Office365Users connector.

I created a sample app using his own credentials on my own hardware and still getting the same error.

I have a textbox control with the Text as Office365Users.Manager(User().Email).DisplayName and it is throwing the following error:

Office365Users.Manager failed: {
"status": 401

"message":"Access token validation failure.\r\nclientRequestId:....."

I have a couple hundred users using this app without any reported issue. Anyone know what may be the cause? He was able to use the app a couple months ago, but has tried again recently and it is not working for him.

In case this occurs for anyone else, going into the Details > Connections of an application, then deleting the connection and have the user re-authorize the connection seemed to resolve the issue.
