OneDrive is a cloud-based storage service offered by Microsoft, which allows users to store and access their files from any device with an internet connection. However, at times, users may encounter an error message that reads “The tag present in the reparse point buffer is invalid”. In this article, we will discuss how to fix this common issue and ensure smooth synchronization between your Windows device and OneDrive.

3. Go to the ‘Account’ tab and check if all folders are synced with your device.

4. If not, click on ‘Choose folders’, select the required folder(s), and click ‘OK’.

Step 2: Clear OneDrive Cache

Clearing the cache can sometimes help fix sync-related issues such as invalid tags in reparse point buffers. To clear your OneDrive cache:
