As Mr. Tanaka is in charge of Mr. Arai, so I will forward the email to him. I told you this many times before, so please check it next time and send me an email. Regards.
The request for Tanaka-san is for Arai-san, so I will forward it to Arai-san. Since this topic has been shared for a long time, please send an email after confirmation.
Arai-san is the contact person of Tanaka-san's matter, so I will transfer this e-mail to her/him. I have told you about this many times, so please kindly confirm that to send the-e-mail from now on.
