It can come with different codes like80090016,80090030,80284001, and so on. All individual error codes represent various causes and may need different solutions.

If all these methods fail,create a new user accountand start using Microsoft 365 from scratch.
Now, let’s discuss all these solutions in detail.
Reset Microsoft 365 Activation State
The first thing you should do is download and run theMicrosoft Support and Recovery Assistant (SaRA) to reset the Microsoft 365 activation state. It will look for most issues with the activation process and automatically deal with them.
Disconnect and Reconnect to the Work Account

Remove Office Credentials
If simply disconnecting and reconnecting with the Microsoft 365 work account didn’t help, repeat the process after removing all the Office credentials. This way, the current credentials won’t affect the reactivation process.
Enable Office Protection Policy
Microsoft also recommends enabling office protection policy before reconnecting with the work account in case the above solutions don’t work.
