If macros are disabled see here

MyFolder is the short name for Session.GetDefaultFolder(olFolderInbox).
Since you did not publish to the Personal Forms Library, by accident you now have a menu choice when in a folder called "MyFolder".
If you want the macro to work point to the "Myfolder" folder.
Replace
Set myItem = MyFolder.items.Add("IPM.Note.Family")
with
Set myItem = MyFolder.Folders("MyFolder").items.Add("IPM.Note.F amily")
Edit: There is no space in Family above. I cannot remove it. Seems to be a glitch in the post.
No idea why you cannot edit your toolbar button. Perhaps it will work when you set your security to medium.
