Can you share the diagnostic report? For the diagnostic report

Hi @stylecreations,

I hope you are doing well.

It seems like a configuration issue; You need to share the Post SMTP Settings > Account tab and Message tab screenshot so that I can review it and get back to you with a solution.

Waiting for your response.

Hi @smakazmi15 ,

Sure!

Hi @stylecreations,

I hope you are doing well.

Actually, it’s a setting or 365 Configuration issue, you can configure any other email account like Gmail and test it if it works fine then it’s an office 365 account configuration issue.

Follow the below guide to configure the account again.

Please follow this?blog here.
