When you try to save these files, you receive the following error message: Note To complete the troubleshooting steps in this article, you may need access to a computer that can share files. For example, you may need access to a computer that has a CD-RW drive, a floppy drive, or a DVD-RW drive. Additionally, you may need access to a computer that does not have Office 2003 SP3 installed.

This issue occurs because Office 2003 SP3 blocks the ability to open files and to save files that may pose a security risk.

To resolve this issue, use one of the following methods, as appropriate for your situation.

Method 1

To resolve the issue when someone else created the file that you cannot open, follow these steps:

1. Ask the person who created the file to save the file in a file format that is not blocked by Office 2003 SP3.
2. After the file is saved in a different file format, open the new file to confirm that it was saved in a file format that is not blocked by Office 2003 SP3.

Method 2

1. Locate a computer that does not have Office 2003 SP3 installed.

3. Transfer the file to the computer that has Office 2003 SP3 installed.
4. Open the file to confirm that you successfully saved the file in a file format that is not blocked by Office 2003 SP3.

Method 3
