This has been happening to some mailboxes for a long time, the only way I know to handle this is to have them log into OWA or online mode and empty the outbox. In all of our experiences the message is in the sent items as well as the outbox. You mentioned that this doesn't happen for you?
You can see which mailboxes have items in the outbox by running this powershell command: Get-mailbox -resultsize unlimited | % {Get-MailboxFolderStatistics $_ -FolderScope outbox} | Sort-Object -Descending ItemsInFolder | ft -AutoSize Identity, servername, ItemsInFolder Microsoft has stated that one of the office patches or updates was supposed to correct this issue but it hasn't worked for us.

Have a few users getting emails stuck in the Outbox. I checked the logs, and the emails are being sent, but they are not moved into the Sent folder. The Outlook profiles are all non-cached, and running 2007, with latest SP and updates. --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
