365 activation key didnt work, now showing too many requests

Hi,

Good day! Just making a follow up, I just want to know how it goes.

Warm regards,

If you are encountering the "too many requests" error after multiple attempts to activate Microsoft 365 with your activation key, it could be due to the system temporarily blocking further activation attempts to prevent abuse. Here are some steps you can take to resolve the issue:

1. Wait for a While: Sometimes, the system may automatically reset after a certain period. Waiting for a few hours before trying again can help.
2. Check Your Activation Key: Ensure that the activation key you are using is valid and has not been used on another account. If you have access to another device or account, try using the key there to confirm its validity.
3. Contact Support: If the issue persists, consider reaching out to Microsoft Support for assistance. They can help verify the status of your activation key and provide further guidance.
4. Use the Microsoft 365 Uninstall Troubleshooter: If you suspect that there may be issues with your current installation, you can use the Microsoft 365 Uninstall troubleshooter to remove any existing installations and then attempt to reinstall Office 365.
5. Reset Microsoft 365 Activation State: You can also try resetting the activation state for Microsoft 365 Apps. This can sometimes resolve activation issues.

Make sure to follow the instructions carefully to avoid further complications.

Hi,

Thanks for reaching out to the Microsoft community and letting us know about the issue with your 365 activation key. I’d like to understand a bit more so we can get this sorted out. When you tried to redeem the key, did you do it through the Office installer or on the Microsoft redemption page at redeem.microsoft.com? Also, can you confirm if the key is for a Microsoft 365 subscription or a standalone Office version? This will help us figure out whether the key is linked to your account correctly and if it matches the product you’re installing.

While we work on that, here are a few things you can try: First, wait for the cooldown period, stop retrying for at least 30 minutes to 24 hours, as repeated attempts will reset the timer. Next, redeem the key online instead of in the installer by signing in at redeem.microsoft.com and entering your key there. If it’s valid, it will link to your account. After that, download Office from account.microsoft.com/services and sign in during installation rather than entering the key again.

If the site says the key is invalid, it could mean the key was already used, is from a different region, or isn’t for Microsoft 365 (for example, it might be for Office 2021 or an OEM version). You can also clear your browser cache or try redeeming on another device, as cached attempts sometimes cause errors.

Please let me know if this helps or if you need more clarification, I’m happy to help!

Warm regards,

Edward

I need to reset the count of active devices. I only have one. I did not complete the set up correctly I think. How do I reset the devices?
