Hello @Vaibhav Mehra
To confirm the situation and suggest the troubleshooting steps in the right direction, may I confirm which macOS version are you currently running?
You can try to update to check if the issue still persists:
- File -> Options -> Update Now
- If necessary, repeat the search several times and then restart your Mac.
For immediate editing of important documents, you can temporarily use Word and Excel on the web.
Besides, you can refer to the thread below, where another user reported a similar experience: Activation error error code 0x0 - Microsoft Q&A (Please translate this thread into your language).
If the issue still remains after trying all the steps above, please share a screenshot or provide more detailed information. I will check the situation and continue to support you.
Kind regards,
