Is previewing PDFs in Outlook 365 Desktop Application with Adobe Acrobat PDF previewer any more secure than just opening the PDF with Acrobat? (zerobytes.monster)

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.
