I understand that you are unable to sign in to Outlook and receive the INTERACTIONREQUIRED message. This usually means Outlook cannot complete the required interactive sign-in or refresh the saved authentication session.
Please try the following:
- Sign in to the same account through Outlook on the web. If you are asked to verify your identity or approve a sign-in request, complete that step first.
- If you are using New Outlook for Windows, close it completely, press Windows + R, enter
olk.exe --clearLocalState, and then reopen Outlook and sign in again. - If the issue continues, open Settings > Apps > Installed apps > Outlook (new) > Advanced options, select Repair, and test the sign-in again.
Could you also confirm whether you are using New Outlook, Classic Outlook, or Outlook on the web, and whether this is a personal or work/school account? This will help narrow down the next steps.
Please feel free to let me know if you have any further updates, thanks.
