Adobe Pro 10.1.16 does NOT detect Microsoft outlook as default client

I already setup Windows 10 OS to acknowledge Microsoft Outlook as the default client; however, when I have a Adobe Acrobat Pro open and I attempt to send the PDF file as an email attachment I get this message: Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client. Please note i'm currently able to send PDF attachments from Outlook, but i would like to be able to send them out from Adobe Acrobat pro.

Is there a fix for this? It has the latest updates for that version and already tried re-installing and repairing Adobe & Outlook. I'm wondering if this version of Acrobat is simply not supported by Windows 10 OR if there is a work around, maybe a registry edit? Please advice.
