All the sudden when I send emails from Adobe Acrobat XI Pro it does not recognize my default mail program (Microsoft Outlook 2013). I've gone to "Edit > Preferences..." and then email accounts. It has the "Default email application (Microsoft Outlook)" checked. But it still persists with the error: "Either there is no default mail client or the current mail client cannot fulfill the messaging requests. Please run Microsoft Outlook and set it as the default mail client."I've set the default mail client as outlook. This service used to work and then all the sudden it stopped working.
