Hi @kanhai hemam
Thank you for posting your question in the Microsoft Q&A forum.
Based on my research, here are a few possible reasons why your Microsoft 365 Basic 1-year subscription might not be activating:
1.The Office 2013 installed is not compatible with Microsoft 365. This likely blocked the automatic activation of your 1-year Microsoft 365 basic subscription.
2.Dell laptops with Microsoft 365 pre-installed use a digital license. This license is triggered only when you:
-Uninstall any older Office versions.
-Sign in to a Microsoft 365 app using your Microsoft account.
-Or go to Sign in and activate from there.
3.Creating a free Microsoft account a few weeks ago is not an issue, that’s what you need to activate the subscription. Just make sure you’re signed in with that same account when you redeem Microsoft 365.
4.Ensure the product key is genuine, unused. Check the characters one more time to be sure you typed the key correctly.
5.Confirm that your Microsoft account’s region matches the region the product key was issued for. Region mismatches can prevent successful activation.
6.If the key still doesn’t work, contact the vendor or retailer where you purchased it.
