Email delivery error

We just recently implemented exchange 2013 into our network and created a new domain.  We are having an issue sending emails to various users that are in the system and have email accounts.  When we try to send out an email we get a delivery error with the following message:

IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=VKUE@NEWDOMAIN.LOCAL
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

This user vkue@newdomain.local has a valid email address internally and externally.  We only get the error when sending to recipients within the domain but if we send from outside of the network from and external address we don't get an error and they get the emails.  Please help or advice on what to look for.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I forgot to mention that we did clear out all cached email addresses and also sent the email from the GAL and still received same error. I will try from OWA to see if I experience the same issue.

I am trying to run the EMS with the command:

Get-MailContact -Identity “cvnadmin” | fl legacyExchangeDN

but get this error:

The operation couldn't be performed because object 'cvnadmin' couldn't be found on 'SERVERNAME'.
    + CategoryInfo          : NotSpecified: (:) [Get-MailContact], ManagementObjectNotFoundException
    + FullyQualifiedErrorId : 870796D0,Microsoft.Exchange.Management.RecipientTasks.GetMailContact
    + PSComputerName        : SERVERNAME

I have tried the alias, full name, smtp address and get the same error with all.  I think it could be the legacyExchangeDN issue that imkottees had suggested.
