Office 365受保护的视图破坏Excel Marcos

Question

Our client has updated to Microsoft Office 365 (Version 1708) and when receiving a generated Excel file (xlt) via email which contains a vb macro, it now displays "PROTECTED VIEW Be careful - email attachments can contain viruses. Unless you need to edit, it's safer to stay in Protected View." - and doesn't run the macro (of course).

Clicking the "Enable Editing" the user gets a runtime error, but in Office 2013 it works fine.

Also in Office 365 if we untick "Enable Protected View for Outlook attachments" and resend the file, it works okay.

Any ideas? Cheers, Steve

Answer 1

After many hours of hacking and googling, we found that this is an existing bug in Office 365.

A workable workaround for us was to change:

Private Sub Workbook_Open()
    Call formatData
End Sub

To:

Private Sub Workbook_Activate()
    Call formatData
End Sub
