Unable to authenticate Office 365 through Connect to Exchange Server from Power Automate Desktop

(4) ShareShare

Posted on by 20

I need help with the Desktop Flow connecting to O365 through this Exchange Server connector. It has been working well for me for a long time. Starting 4 days ago, it stopped working. Giving me this 401 error message. There’s no MFA on this account or my O365 tenant. I don’t know why it stopped working.

Can you help me check? Does anyone has the same issue?

    Same issue here. It's the closing of basic authentication.

    I have a flow with mailtrigger - where the flow is working from the contents of the mail (body or attactments). With modern auth, the flows are now failing.
