Office Activation/Signin Error: New O365 License not activating

Hi,

Today we have one new user joining to our office. To his PC I completed all the software installation and configuration he is going to need but suddenly I am not able to activate his O365 desktop application receiving below errors for last 1 hours.

Error New O365 License not activating. Office ActivationSignin There is a problem with your account.

I am not sure, what I did wrong.

Any hints will be helpful.

Thanks

Step 1: Sign in to Office with the right account

If Office asks you to sign in, enter the account you used to buy Office. You’ll see “We couldn’t find any Office products” if you use the wrong address.

Try this: Sign in to Office

Step 2: Check for multiple copies of Office

You may not realize you have more than one copy installed. Having two installs can cause activation conflicts.

Try this: Check for multiple copies of Office

Step 3: Check your subscription status

If your subscription has expired, you’ll see “We couldn’t find any Office products.” Renew your subscription to use Office 365.

Try this: Check your subscription status

Step 4: Troubleshoot activation

If Office still won’t activate, choose your Office version for additional troubleshooting help.
