Why is my Microsoft sign-in failing with an 'Unknown issue' error, and how can I resolve this access problem?

If this is an organization environment (education or work) and if the problem doesn't fix itself, contact the IT support or local administrator in your organization and ask for further assistance. They can open a ticket with Microsoft business support, if necessary.

Dear @FARHAN LIM, Thank you for reaching out to Microsoft Q&A forum. We are happy to assist.

This appears to be a service-related issue or a temporary outage impacting Microsoft Personal Content services, such as OneDrive or Outlook. The message “We’re on it! Please try again later” indicates that Microsoft is aware of the problem and actively working to resolve it.

Meanwhile you can try these steps to see if the issue persists:

Retry after some time (usually 15–30 minutes).

Try signing in on another network.

Sometimes network restrictions (VPN, school/work network, corporate proxy, DNS filtering, etc.) cause this type of sign-in error.

• Switch to mobile hotspot
• Or try a different Wi-Fi network
• Or temporarily turn off VPN if you use one

This helps determine if the issue is network-related.

Try signing in on another device or browser

Please test sign-in in:

• Another web browser (Edge / Chrome / Firefox)
• InPrivate / Incognito mode
• Another device (phone, tablet, or another computer)

If it works elsewhere, the issue is related to the original device’s cache, session, or browser profile.

Clear your browser cache.

From the screenshot, it looks like you’re using Google Chrome, so here are the steps to clear Chrome’s cache: Clear cache & cookies

Since I do not have access to your device environment, there may be cases where my recommended solutions do not fully resolve the issue or other problems appear. If that happens, please update me right away with any new details or results in the Comment. I will do my best to support you and help find a solution as quickly as possible.
