Resolving the Microsoft Office EXC_BAD_ACCESS error on macOS

Symptoms

When opening an Office application, an error window will appear called Microsoft Error Reporting. The error may read, "there was a problem and Microsoft Word was closed." The window contains a checkbox to Restart the application, an option for More Information, and an OK button. Restart does not resolve the issue.

Click on More Information to see the error log. In the error log, under Error Signature, will be the error code: Exception: EXC_BAD_ACCESS.

Environment

• Operating system — macOS
• Software — Microsoft Office, Word, PowerPoint, Excel

Cause

Error usually indicates a memory access violation, which means that the application is trying to access memory that it is not allowed to access or that it has already released. This can be due to a corrupted Office installation, conflicting software using the same memory resource, outdated software or possibly faulty memory modules
