That may be the definition in Outlook, but other systems define intervals other ways.
E.g., in mathematical notation this is the difference between a closed and open interval, such as:
A: [1,2] closed interval, which includes all values from 1 to 2
B: [1,2) half open, which includes 1,1.1,...1.999999... but not 2
Your issue seems to be that Outlook isn't clear that it incidents appointments as half closed intervals.
