Default e-mail application 'unknown'

[joostb20871753]

When trying to share a pdf via e-mail, the default email application is listed as 'unknown'. In  Windows 10, I have set the standard e-mail to Outlook. When trying to send, there is an error message saying there was a problem sending e-mail.

Hi Joostb,

Sorry for the delay in response.

Firstly, check if there are any pending updates for Reader, to check for update, launch Reader>Help>Check for updates. Try restarting if you installed any updates. Then try to check if you have email client listed in Reader Preferences. To check Launch Acrobat Reader>Edit>Preferences>Email Account, you may set the one which you want if you can see in the list.

You may also want to take a look of this if you want to remove extra steps of new UI: https://helpx.adobe.com/in/acrobat/kb/send-email-attachment.html

Let us know if this works for you.

I have the exact same issue with Adobe Acrobat version 2019.010.20099 on Mac iOS 10.14.3

Both Adobe and iOS is running the latest version.

Standard email program (unknown)

Error message (short version): Can not communicate with standard e-mail program. Chose a different program.
