Over the past two weeks we have covered connecting to Exchange and discovering cmdlets in part 1, and we explored the pipeline in part 2. This week we will be talking about hash tables, arrays and variables. Hash Tables The easiest way to picture a hash table is a list of attributes and their respective […]
