Issue with Embedded Office (Excel) in MFC C++ Application – Macros Blocked in Office 365/2024

(0) ShareShare

Posted on by CU01020650-0

Hello,
I am developing an MFC C++ application and want to embed an Excel file into my form using OLE Object. When I open the Excel (.xlsm) file directly in Office, macros work normally.
However, when I embed the Excel file into my MFC application via OLE, Office blocks the macros, even though I have already taken the following steps:

Actions I have tried:

  1. Added both the source code folder and the Excel file to a Trusted Location.
  2. Enabled VBA/macros in Office settings.
  3. On Office 2021, everything works fine, but on Office 365 and Office 2024 or later, macros are blocked.

Error message:
When opening the embedded Excel file from my MFC app, Office shows "Macros have been disabled."

My question:
Has anyone encountered this issue before?
Is there any way to allow macros to run when embedding an Excel file into an MFC app via OLE?
Are there any additional permissions, registry configurations, or policies that need to be set?

Thank you very much for your help!
