When I send email from the eM Client, some people who have Outlook try to read more than close their Outlook.
are you unable to send emails to Outlook.com domain or this issue is more about reading mails sent from eM Client in Outlook email client?
I will try to explain better, when I send an eMailing email from eMclient version 7.0.27943.0 with digital certificate, anyone who has Microsoft Outlook 2010 gives error and closes, I have already done some simulations and always crashes Microsot Outlook 2010 if it is 2013 or 2016 works normally .
Is this behavior reproduced when you send the same certificate via Outlook 2010 to Outlook 2010?
Perhaps it’s the certificate that causing the program crash.
If sending Outlook 2010 to Outlook 2010 works normally.
