Power Automate Flow Failed - After Turn on MFA

(2) ShareShare
ReportReport
Posted on by 57

I have developed some Power Automate flow with following connectors.

  1. SharePoint
  2. SQL Server
  3. Office 365 Connector

The Flows are triggered from Power Apps.

Everything was working fine before we configured the MFA for the accounts.

 

After turning on the MFA we're getting the below error!

 

Error from token exchange: Runtime call was blocked because connection has error status: Enabled| Error, and sharepointonline is in the block list. Connection errors: [ParameterName: token, Error: Code: Unauthorized, Message: 'Failed to refresh access token for service: sharepointonlinecertificatev2.

 

Now, I checked some Microsoft Document and these are all known issue with flows when we turn on MFA.

https://learn.microsoft.com/en-us/troubleshoot/power-platform/power-automate/conditional-access-and-multi-factor-authentication-in-flow 

 

Question is:

-  how to resolve the connection issue after MFA enabled?

- Is it something we need to tell every users who're using app to go to connections and reconfigure this?

- Also some flows are running from User Context. So, do we need to configure Run Only User as Service account to avoid this issue?

 

Please help me! Really don't understand what to do to resolve this Production Issue!

    I have the same issue. Is there any answers for this?

    Can anybody explain wat must be done, some settings for the user that mace connection between PowerApps, PowerAutomate, SharePoint and OneDrive, or disable MFA for this exact user or something else?

    Hi Dhruvin, any luck with solving this issue?

     

    We just enabled multi-factor authentication, as well, this week. Similar to you, I have a Power App with a Flow that connects to SharePoint, allowing users to upload documents. It's been a breeze, so far, but now the Flow fails at the first step that uses the SharePoint connector. The error code I receive is similar to yours: 

     

    I reached out to my IT team and they mention the same article that you reference in your original post. They said they need to look into it more; I guess this wasn't a foreseen issue. They briefly mention adjusting the flow to use a token policy for the application. Though, I'm not sure what that would entail.

     

    Any leads will help, thank you!
