Flow failing when connecting to Outlook - Unauthorized

[mingo3369]

Over the weekend several of my flows that use Outlook are failing.  The flow will not connect to Outlook, the error is UnAuthorized.

When I resubmit that instance of the flow, it works.

Any ideas?

Take a look at the connection used with an Outlook action in one of your failing Flows.  Does it indicate an issue and prompt you to "fix" the connection?

If that is not the issue, can you tell me what Outlook actions are failing?

No permissions issues to fix.

The actions that fail always involve sending an email.
