prevent save of msg files

I have been trying to figure out a way to prevent the saving of .msg files to the local PC.  We can block saving to network shares, but the ability to drag messages out of Outlook and onto the local machine is something I would like to stop.  I have found that there is a key, which needs to be added,  called "FileSaveBlock" that looks promising, but I am unsure of what DWORD to use.

Full path to key:

Those appear to be for the other apps, so not sure it is going to work with Outlook.
the FileSaveBlock is a KEY under the security tab, so Outlook|Security|FileSaveBlock (if it is going to work like the others).

Then you'll likely need a MsgFiles DWORD or something similar.

Any idea if that is supposed to not give the option, or stop you when you pick it (in the other apps)?
Doesn't look like Outlook was included in that.

Yeah, it doesn't look like Outlook was included, but I was hoping that they had hidden it somewhere in there.
I tried a few things on my 2007 to include MSGFiles, TextFiles, HTMLFiles, with the last two being known good for other Office Apps, so Outlook appears not to care.

I was still able to save as HTML, MSG, TXT, OFT, etc.


Email is the hardest thing to lock down.  Once you have an email, you can forward it to a personal email address and print it from there.
