Save email attachments from Office 365 Outlook to FTP problem pdf

[unibel]

Hi, ran into this problem, have an automatic - saving attachments and then copying them to FTP. Everything was working fine until April 27. Now when I get a pdf attachment to my email, when I open it on the server this file is corrupted. I.e. the machine from the original pdf makes its own file and it is corrupted. I took to check the original pdf and the file, which I received on my ftp server with the help of the machine and it turned out that the difference is a few kilobytes. What can you advise me to do?

I tested the same thing with one drive, the output is a pdf file and a png file. The pdf file is corrupted, the png file does not open. Tested in conjunction all mail from certain e-mail address goes to one drive. And all content from one drive is synced to ftp. The output is a corrupted pdf file that opens but contains half of the information
