And I have one concern does it make any other consequences when I turn the CMT off

Hi All,
Here I'm having an issue with Proxy address,
We are having internal users with upn@mydomain.com and external user with partner.upn@mydomain.com
Let's take an example for partner account: partner.uday@mydomain.com
When a user sends mail to uday@mydoamin.com instead of partner.uday@mydomain.com these mails need to be rejected because there is no user called uday@mydomain.com
But instead of getting the getting rejected these mails are delivered to partner.uday@mydomain.com,
I had searched the users AD proxy address and uday@mydoamin.com is nowhere added to the user.
We had checked the rules fs there is any rule that forwards messages from uday@mydomain.com to partner.uday@mydomain.com but there is no transport rule for this condition.
This is happing for all the partner accounts.
Can someone help me to sort it out.

First, you could use command below to check on your Exchange server, check whether this emails address exist on your Exchange server.
Get-Mailbox -ResultSize unlimited | where{$_.EmailAddresses -match "xyz.@company.com"}
Get-Contact | where{$_.WindowsEmailAddress -match "xyz.@company.com"}
Get-MailContact | where{$_.ExternalEmailAddress -match "xyz.@company.com"}
Then I want to confirm with you that:
