EMail showing From: /O=FIRST ORGANIZATION/OU=EXCHANGE ADMINISTRATIVE GROUP (FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN=users name

I am having a problem with some users when they send an email. the email is showing up in there "sent Items" with the from address showing:
"From: /O=FIRST ORGANIZATION/OU=EXCHANGE ADMINISTRATIVE GROUP (FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN=users name"
The "from address" appears to be showing correctly when recieved by the recipient but I'm not sure that's always the case.
Any ideas on what is causing this issue?
Exchange 2010 / Outlook 2010

Any help on this would be appreaciated.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
