I didn't migrate an email account but "created a new one" with the same email address in a different Domain...same Forest. Removed the Original Account.
I then imported the mail into it. Long story short "very large" email account, very slow Internet line, different City.
Is there anyway that I can fix it as any old emails are getting "Delivery has failed to these recipients"?
Other than restoring the account, then Migrating it and going through the whole process again.
