When attempting to send as an attachment using the Webmail option and a Gmail account, Acrobat comes back with a "Server connection error" and fails to send the pdf. This started failing about a month ago. Prior to that, it worked without issue.
Is there a fix for this?
I have tried it on a Windows 10 and Windows 7 machine.
As per the issue description mentioned above, you are facing issue when trying to send pdf as an attachment in Acrobat, is that correct?
Could you check if an update is available for Acrobat using "Check for updates" option under "Help" menu, reboot the machine after installing update and try again. You may also download updates from here: Adobe software and product updates
