Hello @Yohannes Eshete ,
Thanks for your query.
Did you open Office files in OneDrive Personal? Is there any error message?
Azure Information Protection (AIP) is a cloud-based solution that enables organizations to discover, classify, and protect documents and emails by applying labels to content. When the Azure Information Protection unified client is installed on your computer, you can remove sensitivity labels and protection from files and emails.
