According to your description, you seem unable to save Excel file and got the error, generally we can save file without any problem in Excel version 2103, we’ll try our best to help you troubleshoot it.
To narrow down, please ensure you are usingthe latest version of Excel and check again.
Besides, I notice someone fixed this via Online Repair, if convenient, you might have a try and see the result.
Meanwhile, we would like to confirm some information with you:
