To our Muslim friends, please do not be offended:
Christianity has no official view on Mohammed or the Quran, nor could it because Mohammed and the Quran came about hundreds of years after Christianity.
Christians do have opinions though. To most Christians, Mohammad is no different than any other non-christian who started a religion. They are false prophets and their revelation was a lie from Satan, a delusion, or non-existent.
There are reasons for this. The primary one is the Muslim view on Christ, right in your question. Plenty of Christian Theologians have evaluated Mohammad as a prophet. As far as I know, he has always been found wanting. Mohammad claimed in his writings, the Quran, that Jesus didn't even die. The death and resurrection of Christ is the central point to 99.999% of the various forms of Christianity. This Muslim claim alone is enough for most Christians to reject Mohammad as a prophet. After hearing that, there is very little chance for a committed and educated Christian to take anything from the Quran seriously.
Additionally, most Christians hold the Bible in as high regard as most Muslims hold the Quran. It is the word of God and is without error. The Quran and the Bible stand in contrast on quite a few points other than Christ. They cannot both be from the same God, and since the Bible was first and is already believed to be from God, the Quran, therefore, cannot be from God. That leaves Mohammad as a false prophet.
Similarly, Jews view Christians and Jesus this way. Some teach that Jesus had some good things to say, but he was not even close to what Christians say he was and he certainly was not the Messiah. The revelations of his disciples who started his religion after his death were either lies from Satan, delusions, or non-existent.
There may be a few groups that call themselves Christian that have a favorable view of Mohammad, but I do not know of any. If they exist, they are small in number and it is likely that your average Christian would not consider them Christians.
