In previous versions of Lasernet 9 and 10, an error message may appear informing you that emails have failed to send. This issue may begin with some emails failing intermittently and an “Unable to Post; ChilkatLog” error message is present in the Lasernet log which states the following: 

WindowsError: An existing connection was forcibly closed by the remote host.
WindowsErrorCode: 0x2746
maxToReceive: 5
Failed to receive data on the TCP socket
Failed to read beginning of SSL/TLS record.

Additionally, if you attempt to use Refresh Access Token or Obtain Authorization on the Outlook Mail module, you will receive a dialog with the error “No Response”:

Solution

Multiple fixes have been applied to the Outlook Mail module in recent Lasernet versions. The above error can be resolved by upgrading to Lasernet version 9.15 and 10.3.0.
