Hi I am unique situation plz help me to resolve this issue.

Our company XYZ has XYZ.in domain name and mail server also hosted in hosted service providers linux based mail server.

Now he have decided and implemented our own exchange 2013 with xyz.local domain internally And created users same as hosted service providers.

Eg:-user1@xyz.in (user in hosted service providers)

       User1@xyz.local (user in internal exchange server) 

       User2@xyz.local (user in internal exchange server)

The issue is when we send mail from user1@xyz.in to user2@xyz.local I am able to receive it but when I send mail from user user2@xyz.local to user1@xyz.in it is delivering mail to user1@xyz.local but we are expecting the mail in user1@xyz.in .

Please suggest what maybe  the issue.

please check you have any mail enabled account as user1@xyz.in with the SMTP address user1@xyz.local

or

check you have added any additional SMTP address user1@xyz.in on user1@xyz.local mailbox

As suggested by John please check if you have added @xyz.in as an additional smtp address.

Also try performing a message tracking and see the results
