This appears to be their UK trademark record, http://www.ipo.gov.uk/tmcase/Results/4/EU005097555. [The USPTO trademark search is too blunt a tool for me to be bothered hunting that registration down at the moment.]
This http://www.ipo.gov.uk/tmcase/Results/1/UK00002215537 is a registration of the trademark "box" for the relevant computer and communication classes (inter alia 9, 38, 42) which was filed about 7 years before Box UK filed their application. TBH I can't see how the later one was granted RTM status except that this one appears to be an image mark.
"Box" is widely used as a trademark and other companies are using it in the same class. Box presumably can't make the case for infringement of their mark without also making the case that they're infringing someone else's - Boks™ belonging to a Norwegian company for example. It's pretty generic as a term for storage/term in computing.
That aside Dropbox would only be problematic if there was genuine confusion. For example Box UK had a series of offerings with trademarks using "box" as a suffix. If Dropbox were considered infringing, for example, Xbox would also be infringing as they operate within the same class - Box presumably haven't challenged the use of Xbox [which probably predates their use anyway].
