Narrative:

There was one hazmat item which was supposed to be placed on our aircraft. We had asked that the item be removed shortly before departure time. It took the station several minutes to locate the item and remove it. The cargo door was closed a few minutes after our scheduled push time. Though it would be easy to assume that the delay for the cargo door was related to the hazmat removal; we left nothing to chance and contacted operations by voice at this time to double check and make sure the item had been removed. They said it was removed. With this complete we were now ready for push. All checklists and normal operational procedures; (and required paperwork) were complete for our known configuration. Then; during taxi; we received an 'auto generated' computer message which was sent to the aircraft. It briefly describes what hazmat items are planned to be on board. Not too surprisingly; it still showed the hazmat we had been told was removed. Being diligent however; we took the time to call the station one more time before we took off to confirm that they had indeed removed the item; that there was no hazmat of any kind on the aircraft; and that the message had been generated in error. They were emphatic that 'yes'; the hazmat item had been removed; the auto generated message was not correct. About 2 hours later over the north atlantic we were informed by dispatch that the station had made a mistake and removed the wrong pallet. The hazmat was still on board. We then had dispatch send the dangerous good summary over ACARS to complete the required paperwork for our updated configuration. We looked up the details for the drill code actions just in case there was an issue with the item and proceeded on with the flight without further incident.
