Telling a document to save with a filename ending with .doc doesn't actually MAKE it a Word 2003 doc format. The suffix is a rough indication of what the file type should be but doesn't actually control the file type in itself.
If your filename.doc still contains Content Controls then the actual filetype is probably docx or docm.
If you want to change the filetype then you need to specify this
Code:
ActiveDocument.SaveAs2 FileName:=strDrive & fisword & ".doc", FileFormat:=wdFormatDocument
' or
ActiveDocument.SaveAs2 FileName:=strDrive & fisword & ".docx", FileFormat:=wdFormatXMLDocument
