JasperReports Scheduler not sending emails using Office365

[cruisebright]

Hi

Could someone please suggest on how to debug the below problem ? It is not logging anything in the log files. (Ubuntu OS)

I'm unable to send emails using the report scheduler.

Below are the last lines in js.quartz.properties

report.scheduler.mail.sender.host=smtp.office365.com

report.scheduler.mail.sender.username=username@domain

report.scheduler.mail.sender.password=password

report.scheduler.mail.sender.from=username@domain

report.scheduler.mail.sender.protocol=smtp

report.scheduler.mail.sender.port=25

Below are the lines from applicationContext-report-scheduling.xml 

 <bean id="reportSchedulerMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

        <property name="host" value="${report.scheduler.mail.sender.host}"/>

        <property name="username" value="${report.scheduler.mail.sender.username}"/>

        <property name="password" value="${report.scheduler.mail.sender.password}"/>

        <property name="protocol" value="${report.scheduler.mail.sender.protocol}"/>

        <property name="port" value="${report.scheduler.mail.sender.port}"/>

        <property name="javaMailProperties">

            <props>

                <prop key="mail.smtp.sendpartial">true</prop>

                <prop key="mail.smtp.auth">true</prop>

                <prop key="mail.smtp.starttls.enable">true</prop>

                <prop key="mail.smtp.starttls.required">true</prop>

            </props>

        </property>

    </bean>
