Is there a way to make Adobe X use a person's default mail client instead of only Outlook? Our organization uses primarily Thunderbird. When viewing a PDF and choosing File > Attach to Email (or clicking the envelope toolbar button), Abobe X attempts to use Outlook, which is either not available on our clients' PCs, or not configured for email at all.
This possible has to do with a wrong MAPS setting in your OS.
You have to configure which app uses the mailTo protocol per default.
