Mail Manager has made if easy for any authorized individual in our company to search under key technical topics / key words and to easily identify who in our organization may have past relevant experience that can be applied to current projects. It's allowed us to instantly call up recent emails related to pressing issues to rapidly prepare for an unexpected meeting. It's radically reduced wasted time spent searching our email database, and increased accuracy and thoroughness of the results. It has dramatically reduced the amount of server storage space needed for email messages.
