Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,
May I know where the files are currently saved on your device?
- Are they stored locally on your computer's hard drive, or are they saved in a cloud storage location such as OneDrive?
- Are the files stored in the Documents folder? Please note that if the Documents folder is being backed up or synced with OneDrive, it is a OneDrive-synced folder rather than a local folder.
So, if the files are stored in OneDrive and there are any sync issues, you may be experiencing issues when opening the saved Office files.
- Make sure your device is connected to the internet.
- Then, right-click the OneDrive icon on the taskbar and see if there are any sync error messages.
- If any errors appear there, share the error message here. (OR) you can follow the steps in the article here to reset OneDrive: Reset OneDrive
Alternatively, go to https://onedrive.live.com/ in any web browser and sign in with your Microsoft Account.
See if you can access the files on OneDrive Online.
