Hi, if i use tDropFileSource with

mytDropFileSource.files.add(vpathtoafile); mytDropFileSource.Execute;

i can drop files to desktop but not to Outlook 64bit. Is this a known limitation somehow with 32bit and 64bit apps or is it a bug?

Can be tested with SimpleSourceDemo, Drag&Drop a File to a new E-Mail from Outlook-2019 in 64bit and it will not dropped into the new e-mail ...

It seems to be a outlook bug.
