How to fix 'Microsoft Office has detected a problem with this file' error in Windows?

“Microsoft Office has detected a problem with this file” error is a relatively uncommon error that happens to some users upon trying to open or edit files in Office applications such as Word, Excel, or PowerPoint. The error message typically suggests that Office has found corruption or incompatibility within the file, and therefore, it is unable to display content appropriately.

Apart from file corruption and incompatibility, security measures can also lead to the “Microsoft Office has detected a problem with this file” error. Overzealous antivirus software or over-restrictive Windows security levels will occasionally block a portion of a file or macros within, recognizing them as potential malware, thus preventing proper file opening.

File corruption can occur due to sudden shutdowns, incomplete saves, or even malware infections that impose damage on a file's structure. Moreover, incompatibility among different Office versions can lead to issues when a document created in a newer version is opened in an older version.

Aside from these common issues, excessively stringent security settings – such as high macro security levels – can contribute to the error by blocking necessary content within the file. In this way, users can receive the error message “Microsoft Office has detected a problem with this file” even when the document appears to be fine.

Users experiencing this error generally find that their documents will not open, or they will open partially with some data and formatting lost. Troubleshooting generally involves verifying the integrity of the file, verifying compatibility between Office versions, and verifying security settings within both Office and within any installed antivirus software.
