Hi @Jemin Prajapati ,

Have you decommissioned Exchange 2010 server in your environment?

According to your error message, it indicates that the value for the “CN = xxx” is taken from the alias property of the user being migrated from the old exchange server. In this case, we recommend you compare your AD properties between two servers. You can also try to delete the old “IM Override” and renew another name.
