Company domain email address didn’t receive the contact form 7 message

I am using my company domain email address on the “mail (2)” for long time to be able to receive a message. the form message was successfully sent and received by the customer email address, however it suddenly I didn’t receive any message from contact form 7 as a copy of the form message.

I tried my personal email address like @gmail.com and @outlook.com on “email (2)” and both were successfully fine and received.

Any idea on how could I fix this issue?

Thank you in advance.
