Excel VBA SaveAs "Read-only" PDF file

The following code successfully saves an excel sheet as PDF. I would like to save it as a file, that can be opened by everyone, but not edited with the "fill and sign" feature, that is provided by Adobe Acrobat Reader DC. I have tried to simply add the following, but that does not work:

Attributes:=vbReadOnly

Here is the rest of the code:

Dim sPath As String

sPath = "O:\"

With Worksheets("Sheet 1")
    .ExportAsFixedFormat _
        Type:=xlTypePDF, _
        Filename:=sPath & UserForm.TextBox1.Value & ".pdf", _
        Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, _
        IgnorePrintAreas:=False, _
        OpenAfterPublish:=False
End With

Solution 1:

You should be able to use SetAttr after saving.

SetAttr "c:\path\yourfilename.pdf", vbReadOnly
