You can set tile outside but in a freeze/thaw area it needs to be a porcelain tile or a quarry tile, these types wont absorb moisture to the point where they can freeze and crack. A good modified thinset must also be used to set the tiles. The grout should be one that can be mixed with a latex additive, rather than water, to reduce water absorption. Check the back of the bag or ask someone on the showroom floor if their grout can take the additive. Some cant and say so on the bag.
