wxanl Posted June 6, 2023 Share Posted June 6, 2023 We have the situation that mail delivery from prestashop 1.7.7.1 mail alerts suddenly stopped with a error message (connection refused). We are using the smtp option with the right credentials for an office35 account. That used to work. According to the techs at the hosting the problem may be caused because Office 365 now requires TLS 1.2 minimum to connect. Can anyone tell me what TLS version prestashop is using or how to fix this problem ? Error: Please check your configuration Connection could not be established with host smtp.office365.com :stream_socket_client(): unable to connect to tcp://smtp.office365.com:587 (Connection refused) Link to comment Share on other sites More sharing options...
