LSUMail: Why Do Some E-mail Addresses Show Up As

Not every LSU person has a mailbox in LSUMail.

However, most of these people are defined in the LSUMail Global Address List so that you can see their names and addresses when you select them as recipients of your e-mail. To make e-mail delivery work, those people who do not have an LSUMail mailbox have a routing address of The address tells LSUMail to sent the message back to the LSU campus for proper routing and delivery.


In OWA Mike The Tiger wanted to check the e-mail addresses of all the 'tiger' accounts at LSU.  He clicked on the TO button while composing his e-mail.

1. He then typed 'tiger' in the search input box.

2. Below is what OWA displayed when the system finished searching for  the "tiger" name.
