We have some folks in my organization that use the Adobe Acrobat PDF previewer in the Outlook desktop application to preview PDFs, and I was wondering if it has any additional security precautions (for example, is it a sandboxed environment?) versus fully opening the file in Acrobat with JavaScript disabled and Protected Mode enabled. Any insight is greatly appreciated.

Edit: to be clear, I don’t think it’s “safe” to open PDFs with Acrobat. I am just curious if the previewer is any less unsafe somehow.
