This error may appear if you attempt to open a file marked as damaged or disabled by a Microsoft Office program. Each time the file is opened, even if the file was recovered or repaired, this error appears and other open files or programs will be suspended.
The file is in the Disabled Items list because, in previous attempts to open the file, it has caused a program error or shut down more than once.
If the file was properly recovered, replaced, or deleted, you can remove the file from the list of disabled files (re-enable the file) by clicking the File tab, clicking Options, and then clicking Add-Ins. In the Manage list, click the arrow and select Disabled Items, click Go, and then select the disabled item that you want to re-enable.
Re-enabling a file does not guarantee the application can open it. The file must be recovered from either a backup or undamaged recovered file.
