Hi lucie,
There was misunderstanding in this scenario.
This is the workaround that we found and work with it.
But when I create sub domain it give me MX record invalid.
If i put my domain the MX record give me invalid.
So what i did was this workaround.
But i need to send and receive the emails from the same domain with the same mail.
Not to forward the email to purecloud domain.
I hope you understand stand the scenario now.
To make sure from what i said(add any domain in purecloud)
The first thing you will faced is MC recode invalid.
The only domain that didn't waiting for verification was purecloud domain.
So we use this workaround.
Best regards
