Unable to open icloud account on outlook despite it working on Friday & passing all authentication phases today

Question

I'm trying to open my already registered icloud account through outlook - this worked perfectly fine on Friday, and despite passing all authentication this morning, it keeps going back to the beginning authentication page.

It sounds like you are experiencing an issue with the authentication process for your iCloud account in Outlook. This can sometimes happen due to various reasons, such as cached credentials or issues with the authentication settings. Here are a few steps you can try to resolve the issue:

1. Clear Cached Credentials: Sometimes, saved credentials can cause problems. You can clear them from the Windows Credential Manager if you are using Outlook on Windows.
2. Re-enter Credentials: After clearing the cached credentials, restart Outlook and try to sign in again with your iCloud account credentials.
3. Check for App-Specific Password: Ensure that you are using the correct app-specific password for your iCloud account, especially if you have two-factor authentication enabled on your Apple ID.
4. Update Outlook: Make sure your Outlook application is up to date, as updates can fix bugs and improve compatibility.
5. Use Advanced Setup: If the standard setup does not work, try using the advanced setup option in Outlook to manually enter your account settings.

If the issue persists, you may want to consult further resources or support for additional troubleshooting steps.
