    Follow step-by-step instructions below to troubleshoot the issue. Complete prerequisites step before proceeding to error troubleshooting step.

    1. Prerequisites

    Check your mail server configuration. Acronis supports only SMTP protocol for sending messages. If you are trying to connect to Exchange server make sure it is configured properly: Configuring Exchange Server for E-mail notifications (Use solution from Exchange 2007 for Exchange 2010 and 2013).

    If this requirement is met and issue still persists, go to error troubleshooting step.

    2. Error troubleshooting

    Complete all steps before proceeding to collect information step.

    2.1 Test e-mail notification works but regular e-mail notifications about backups fail

    Most probably you are testing email notification from Acronis Management Server, however the backup e-mail notifications are sent from Acronis agents installed on the managed machines. On the Management Server, navigate to Machines with Agents and connect directly to agent that failed to send a notification. Click Options -> Machine Options. Send test e-mail from E-mail Notification options menu. It will fail too. Proceed to the next troubleshooting steps.

    2.2 Antivirus Software

    If any firewall, antivirus or other security software is installed on the machine, make sure that the following Acronis processess are added to the list of trusted applications in the security software:

    Acronis Software: Making Acronis Products Compatible with Antivirus Software
    Acronis Software: Making Acronis Products Compatible with Third-Party Firewall Software
    For the full list of Acronis processess please refer here: Acronis Backup & Recovery 11.7/11.5: Windows Services and Processes.

    2.3 Use correct Ports for the servers and encryption settings

    Use correct Ports for the SMTP server.

    1. Typical port for unsecured connection: 25
    2. SSL: 465
    3. TLS: 587

    Use correct Ports for the POP3 server if "Login to POP3 server before SMTP" is required.

    1. Typical port for unsecured connection: 110
    2. TLS/SSL: 995

    If you are not sure what port is your server is configured to be working on or about encryption you can use telnet to check: on a machine where your emails work fine in your email client use telnet to check above ports. If the telnet works on specific port - then your server listens on it and you can use the encryption settings from above for the particular port. E.G. if your SMTP server listens on port 465 then you most likely have to set encryption to SSL to send notifications.

    You can also check if specific settings are correct by manually sending email through telnet.

    2.4 Check Firewall and Network

    This is the most common cause in case test e-mail notifications from the Management Server are sent correctly, but fail to be sent from the Agent machine. Sometimes there are specific firewall rules that forbid specific machines from accessing the SMTP server. In this case use telnet to check if the ports are accessible from the agents. To find what ports you need refer to 2.3 of this article.

    2.5 Incorrect Settings specified for the SMTP server.

    Make sure that you are really using correct settings for the SMTP server. If you are using some kind of SMTP service provider such as Gmail then please refer to their support pages such as this one Gmail settings for Mail Clients. If you have your own SMTP server please refer to its configuration to be sure.

    Do not enable encryption in ABR if it is not required by the server.

    Do not enable "Login to POP server before SMTP" if it is not required by the server.

    If these steps have been executed and the issue still persists, collect the information listed below and contact Acronis Support for further help.
