Hi Angelito Patricio,
Thank you for your posting in the forum community.
I’m writing to follow up on this thread. Can we know please have you referred the above mentioned information article which is provided by independent advisor “Palcouk”?
If the issue still persist, at once can we know please which Office 365 subscription you are using?
Regarding this error message, it seems like the file is damaged into the operating system, at once we would like to suggest you to please uninstall Office via using Microsoft support and Recovery Assistant,
after that download and re-install again Office from the Office portal. Here are the detailed information articles:
1. Uninstall Office from a PC
2. Download and
install or reinstall Microsoft 365 or Office 2019 on a PC or Mac
Note: Before uninstalling Office, please take a backup of whole Office data into another location for data loss prevention.
Please feel free to contact us and provide us some brief information about your Office subscription details so we can further assist you accordingly. We are highly appreciated your cooperation and understanding
in our forum community.
Regards,
Darpan
