If you want to know more about how Excel saves files, see the Process for saving an Excel file section.

To troubleshoot an Excel save issue, follow these steps in the order that they appear until the problem is resolved.

Step 1: Try to save the Excel file to another location

If you can save the Excel file correctly when you save it to a local hard disk drive, to a network drive, or to a floppy drive, the following are possible causes for the issues that you are experiencing:

• Antivirus software conflict
• Restricted permissions
• Network connection lost
• File name length
• File sharing conflict

If you cannot save the Excel file correctly when you save it to a local hard disk drive, to a network drive, or to a floppy drive, the following are possible causes for the issues that you are experiencing:

• Transition Formula Evaluation feature
• Template contains an embedded object

If neither of these are the cause, try step 2.

Step 2: Try to save a new Excel file to the original location

To save a new Excel file to the original location, follow these steps:

1. Create a new Excel workbook.
2. On the File menu, click Save As.
3. In the Save As dialog box, follow these steps:
   
   1. In the Save in box, click the location where your original Excel file is saved.
   2. In the File name box, type a new name for your new Excel file.
   3. Click Save.
   
   

If you can save a new Excel file to the original location, the following are possible causes:

• File name length
• File sharing conflict

If you cannot save a new Excel file to the original location, the following is a possible cause:

• Insufficient drive space

If you have sufficient drive space, try step 3.

Step 3: Try to save the Excel file in Microsoft Windows Safe Mode

If step 1 and step 2 has not resolved the issue, restart Windows in Safe Mode, and then try to save your Excel file to your local hard-disk drive.

Note If you use a network location to save your Excel files, try to restart Windows in Safe Mode with network support, and then try to save your Excel file.

• Terminate and Stay Ready (TSR) program
• Antivirus software conflict
• Restricted permissions
• File name length
