How do I find email messages using old domain name?
I need assistance in finding any email traffic that is being used by and old domain in our company. The company I now work for has an old domain name (MyOldDomain.net) that they no longer use in production and the director wants everything to use MyDomain.com.
The users had the SMTP addresses with the old domain name removed and up to two years ago all applications and devices used emails with the old domain name. I have updated as many of the applications and devices I can find but I need help in finding any email traffic for @MyOldDomain.net.
The message tracking in the EMC are not wildcard friendly and my PowerShell attempts have come up dry.
