Send Mail not working

Hello,

I am facing a strange problem.

I am trying to send mail from workflow. I have created a workflow with just one send mail step. When I execute the workflow, the workflow gets completed stating mail sent. But the mail is not received in my outlook.

I have checked the following:

1. Workflow Automatic Customizing is properly done(The RFC Destination WORKFLOW_LOCAL_CCC is configured)

2. The user WF-BATCH has email ID and communication method as RML. I also tried with communication method email.

3. In the SCOT the settings are correctly done. When I send the mail from SBWP it is sending mail and receiving in outlook successfully.

However when I check SOST, I was unable to see any mail request from my workflow.

How can I debug this and solve the problem. Any help will be appreciated.

Regards,

Shubham
