Galaxy S5 One contact on phone not syncing with Exchange

I have one contact in my exchange contacts on my phone that does not want to sync with the exchange server. It originally must have come from the exchange server because the info is very detailed. The contact does not appear on the Exchange server and consequently does not appear on my computer Outlook. I added new contact entry on my computer using slightly different info and new contact appeared instantly on phone. What up with this miscreant contact?
