  • Hi Ravi

    In error do you see name of remote server, if that exchange server is yours than please check for Hub Transport Rules and make sure there is not unintended block rule created.

    In case you find remote server is from another sender domain then try receiving email from hotmail or gmail and see if you receive it or not? If you find issue with specific sender domain then you can involve their IT Support to work with you.
