Why is the domain name on my hosted exchange account uppercase?

1 month ago I changed providers for my hosted exchange email account and website from a firm I was having problems with to Network Solutions. My company's domain name was purchased through Network Solutions many years ago, so that did not change. Prior to migrating the accts to NS, whenever I emailed someone, they would see my email address as "myemail@mydomain.com", which is fine. After the migration, all email recipients now see "myemail@MYDOMAIN.COM". I realize this has no effect on functionality, but it doesn't look right to me. Where do I go to correct this (email is on a hosted exchange account through NS). How do I change this to all lowercase letters? No changes were made to my domain controller.

Under your accepted domains is the domain.com all uppercase?  Also might be under your default email address policy.

The domain controller shows domain name all lowercase, and it wasn't touched during the migration. Email is a hosted exchange account through Network Solutions. I don't think I have access to see the default email policy. NS said they can't help because they are just resellers of the hosted exchange service. They said I need to contact Microsoft. If that is the case, I know how this is going to turn out.....

It would be on Network Solutions side as to how they setup your accepted domain on the exchange server.  It would be their issue.

For example on my exchange server I open EMC and want to add a domain or even when I go to build it it asks for your domain name.  Much like dns  if I add the entry DOMAIN.COM, it will show up as DOMAIN.COM.

I am not sure of how this service works but it would be on their end as to how your hosted exchange is setup and needs to be adjusted.
