Has the receiver had a name or email address change recently?

It's likely that the old address is cached in your clients Outlook/Exchange accounts. This will vary depending on which version you're running.

Previous to 2010, the nickname cache was stored on the client machine as a .nk2 file. If this is the case, you will need to delete all the senders' .nk2 files. These are stored in %appdata%\Microsoft\Roaming\Outlook.

Outlook 2010 and later stores the nickname cache on the server.  To delete the cache have the user do the following in Outlook:  Click File > Click Options > Click Mail > scroll down to the Send messsages section > Click the button that says Empty Auto-Complete List >  Click Yes on the message that asks if you are sure you want to empty the auto-complete list >  Click OK on the Outlook Options window > Exit Outlook, then re-launch the application.
