Flows working fine. Added Conditional Access to require MFA and failures started the next morning.

Flows are created using a Premium License - users have regular licenses.

User MFA's to SharePoint site
Accesses Power App to start the flow
First failure is at action "SharePoint Get Item"
Same user submits another request - will succeed at "Get Item" but fail at "Outlook Send Mail"

Doesn't happen for every user. Trying to address this before larger scale rollout of the Conditional Access policy. Below is the failure on Get Items - the Outlook error is the same except it references 0365 in the block list.

Error:

}
}

The MS suggestion to have the user log into Power Automate to fix the connection isn't a solution since the second time they submit a request - it passes the Get Item action so it isn't the connection.

Help!
