office365users in block list error.png My Flow keeps intermittently failing with the following error: "Error from token exchange: Runtime call was blocked because connection has error status: Enabled| Error, and office365users is in the block list."

It does this for some users but not all of the time. Any help on how to fix this would be greatly appreciated.

Hi @LaurenLCF,

I have made a test on my side and don't have the issue that you mentioned.

And I couldn't identifier the flow error from the error message that you provided.

Could you please share a screenshot of the configuration of your flow?

Could you please take a try to create a new connection to the "Get Menager" action or delete it then re-add it in the flow?

Please share more details so we would try to provide a proper workaround for you.

Best regrads,

Alice

Hi Alice,

Thank you for trying to help. Attached is a screenshot of the flow configuration.

Is there a preferred version of the "Get Manager" action to us? I know that there are two.

Best,
Lauren

I have the same problem with the 'Get Profile' action within O365 Users. The user is on the 'block list', but the user has a complete office account. Full text: "Runtime call was blocked because connection has error status: Enabled | Error, and office365users is in the block list. Connection errors: [ParameterName: token, Error: Code: Unauthenticated, Message: 'This connection is not authenticated.']"

I noticed Status code 401 & "x-ms-failure-cause = apihub-token-exchange" within the Get O365 Profile error details. See my flow configuration below. The UPN is a text string from the 'Get Item' action with a complete email address ('first.last@company.com')

My flow worked and still works 98% of the time. Please direct me to anything that may help.

I have the same problem, did somebody find an explanation and how to avoid it? In my case I get the error when I try to send an email using the Outlook connector.

Any ideas or solutions? I refreshed my connection, but it sounds like it is intermittent.

Please verify the connections for all users experiencing this issue. As I recall, my issue was resolved when the connections for these three users were fixed. Additionally, we encountered a problem when our IT support company enabled two-factor authentication (2FA) for all Office 365 users.
The user who creates and shares the workflow should not have 2FA enabled. Since I created the workflow and shared it with my colleagues, everyone faced problems with the workflow connections when 2FA was activated for me.
