Unable to establish connection with outlook 2010

The reason why you are unable to connect the inbox.lv mailbox in the Outlook 2010 e-mail program is related to the security protocol TLS (encryption protocol used to encrypt information transmitted over computer networks) TLS 1.1 is used as the default protocol version in Outlook 2010, but updated antivirus programs are only able to work properly with the security protocol TLS 1.2 or later, which results in a failed connection.

In order to be able to successfully connect the inbox.lv mailbox to the Outlook 2010 e-mail program, it is necessary to disable the e-mail protection of the antivirus program for outgoing e-mails, or to make changes in the computer registry

  1. Open an antivirus program (eg Avast Free Antivirus)
  2. Go to the Protection section
  3. Under Protection, you choose Core Shields
  4. And uncheck Scan outbound emails (SMTP) so that it is disabled

       5.When a new folder is created, right-click on it and select Rename and change its name to TLS 1.2


       6.When the folder is renamed, right click on it and create a new sub folder New->Key and name it Client

       7.Right-click on the Clinet folder and select New -> DWORD (32-bit) Value
