Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Please provide some more information on this problem,
Was the Microsoft 365 subscription pre-installed on the laptop?
If so, Microsoft Office licences are region specific, if the device was purchased in Australia and moved to the Philippines before Office was activated, that is the most likely cause of the problem, the best option is to contact Microsoft Support directly to ask them if it will be possible to activate that Office licence in the Philippines, try using this method to contact their support.
