Since upgrading to OSX High Sierra the SendMail function doesn't work anymore in Acrobat DC. I keep getting the message"The SendMail doesn't know how to talk to your default mail client. Please select a different mail application to use." I don't have another mail application. I already reinstalled Acrobat but that didn't solve the issue.
What to do?
I have not upgraded to High Sierra yet (I always wait until I have either a business need to use the latest, or until I buy a new computer), so I don't have any first hand experience. However, this sounds like a bug in Acrobat DC, and the first thing I would do is to make sure that I am running the latest version (go to Acrobat's Help menu and select "Check for updates"). If you are running the latest version, I would report this as a bug to Adobe: Feature Request/Bug Report Form
