Acrobat X Share Issue

[larryc89436001]

Hello,

Whenever I try to share something out of Acrobat I'm getting this error: "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." Then, "An error occured while sending mail." I've had people from Microsoft support remote in and work on Outlook, but after checking every setting they could think of they think it's an Adobe issue. Any idea what could be going on or what the fix could be?

Thank You

This had been working fine, and stop working suddenly a few days ago without any changes to my machine.
