Dear @Naval Kishore,

Thank you for posting your question in the Microsoft Q&A forum.

According to Microsoft, “This item might not exist or is no longer available” commonly appears when the default document library name in OneDrive is changed from “Documents” to a different name.

To fix the issue, the document library must be renamed back to “Documents”. This requires administrator permissions. In this case, Microsoft provides two supported methods:

Option 1: Microsoft 365 Admin Center

An administrator can run the OneDrive diagnostic in the Microsoft 365 Admin Center. If the diagnostic detects that the default document library name was changed, it can automatically reset it back to Documents.

Note: This diagnostic is not available for GCC High, DoD, or Microsoft 365 operated by 21Vianet.

Option 2: SharePoint Designer

An administrator can open the user’s OneDrive site in SharePoint Designer > Go to All Files > Rename the document library back to Documents

Microsoft does not recommend using SharePoint Designer for regular OneDrive customizations, but it can be used to correct this specific issue.

Important: If you don’t have admin permissions, I recommend contacting your Microsoft 365 administrator and sharing this Microsoft article so they can apply the fix: "This item might not exist" error when accessing OneDrive

If the issue still persists, to better understand what’s causing this in your specific scenario, could you please help clarify a few points below:

• Is the PDF located in a standard Teams channel, a private/shared channel, or in OneDrive with a shortcut added to Teams?
• Does the issue occur only when opening the file inside Teams, or does it also appear when you open the Teams-generated link in a browser or open in OneDrive?
• Does the problem affect only PDFs, or do other file types (Word, Excel) show the same error in Teams?
• Could you access to the Microsoft 365 Admin Center?

Note: Please understand that as a forum moderator, my role is to provide general guidance and troubleshooting support. I don’t have access to internal systems or backend tools, and I appreciate your understanding of these limits.

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

Thank you for your patience and understanding. I'm looking forward for your reply.
