How to Fix Adobe Send and Track Files Returning 404 Errors
Question details
Users are encountering a 404 Not Found error when attempting to open file links shared through Adobe Send & Track.

- Product
- Adobe Send & Track / Document Cloud
- Device & OS
- not provided
- Scenario
- Opening or sharing PDF files via the Adobe Send & Track web service or application.
- Observed behavior
- The shared file links return a 404 error, preventing recipients from accessing the files even when they are uploaded from different computers.
Ensure that the shared file link has not expired and that the original file has not been manually deleted from the sender's Document Cloud account.
Clear Old Files from Adobe Document Cloud Storage
Full or cluttered Document Cloud storage can cause link generation to fail. Deleting unneeded files frees up space and resolves tracking link issues.
When your Adobe Document Cloud storage reaches its limit, the Send & Track service may fail to properly host new files, resulting in 404 errors for the recipients. Managing your sent files resolves this server synchronization problem.
Access your Adobe Document Cloud account through your preferred web browser and sign in with your credentials.
Go to the 'Sent Files' or 'Shared' section from the main dashboard to view your previously shared documents.
Select old files that are no longer needed and delete them to reduce your stored data.
Once storage space is freed, upload your PDF again and create a fresh Send & Track link.

Use the Adobe Acrobat Reader Desktop Application
Bypassing the web interface by using the desktop application can prevent browser-based uploading and synchronization glitches.

Frequently Asked Questions
Why do my shared PDF links suddenly show a 404 error?
A 404 error typically means the file cannot be found on the server. This happens if the file was deleted from the sender's Document Cloud, the storage limit was exceeded preventing a successful upload, or the sharing link has expired.
How do I know if my Adobe Document Cloud storage is full?
You can log into your Adobe Document Cloud account via a web browser and check the storage indicator at the bottom left of the files menu to see your current storage usage and limits.
Can I fix a 404 error on a link that was sent to me by someone else?
No, the 404 error must be resolved by the original sender. The sender needs to log into their Adobe account, clear up storage space if necessary, and generate a new sharing link to send to you.
