we cant attach the pdf  to an email from adobe reader

Hello:

We have some computers with Acrobat Reader  & New Outlook for Windows.  When the user opens a PDF file clicking on the mail icon the program use to launch the email client (old outlook for windows 2016) and attach the file to the message so we can write the rest of the fields and then send the e-mail.

Since the new outlook for windows was installed we get an error saying there is no email associated. we have the new outlook for windows set at the default email client in the control panel (windows 10)

So for now we cant attached the pdf  to an email from adobe reader.

Is there any solution?.

Any help is appreciated/

Thanks,

chris
