Fix Acrobat Error 105: Problem Reading Document When Saving PDF
Question details
The user is unable to save a PDF file in Adobe Acrobat due to a document reading error.

- Product
- Adobe Acrobat Pro XI
- Device & OS
- not provided
- Scenario
- Attempting to save modifications made to an opened PDF document.
- Observed behavior
- Acrobat blocks the save process and displays the error message: 'The document could not be saved. There was a problem reading this document (105).'
Before attempting any fixes, do not close the current Acrobat window to avoid losing your unsaved edits. Ensure your local hard drive has sufficient free storage space.
Use 'Save As' to a New Local Folder
Saving a fresh copy to a different directory on your local drive often bypasses network disconnects or temporary file conflicts causing the read error.
Network latency or synchronization issues with cloud folders (like OneDrive or Dropbox) can interrupt Acrobat's ability to read and overwrite the source file, resulting in Error 105.
Click on 'File' in the top menu bar and select 'Save As...'.
Choose a local folder on your computer, such as your Desktop or Documents folder, ensuring you avoid mapped network drives.
Enter a completely new file name to prevent overriding conflicts.
Click the 'Save' button and check if the process completes successfully.

Print to PDF as a Workaround
If standard saving continues to fail, 'printing' the document to a new PDF flattens the file and strips away structural errors blocking the save operation.
Check Folder Permissions and Network Connection
If the source file is stored on a server or a restricted folder, correcting the access permissions will allow Acrobat to save the file properly.

Frequently Asked Questions
What causes Acrobat Error 105 when saving a PDF?
Error 105 typically occurs due to momentary network drive disconnections, corrupted background file structures within the PDF, or insufficient read/write permissions in the destination folder.
Will I lose my PDF edits if I encounter Error 105?
If you close Acrobat without successfully using the 'Save As' or 'Print to PDF' workarounds, your unsaved edits will be lost. Always attempt to export or print the document before closing the program.
How can I prevent PDF saving errors in the future?
To minimize saving errors, try transferring files to your local drive before editing, ensure your PDF software is up-to-date, and avoid having the same file open simultaneously in multiple background applications.
