Cloud-based email is now solidly established in many large enterprises, due to the substantial cost benefits. Cloud-based email offers savings that can add up fast, so enterprises should evaluate shared-tenant versus private cloud options. Another strong advantage of cloud email is the large quantity of storage for each individual account. An exponential increase in mailbox size can improve employee productivity.
Email now has more tools for better management at the user level. Client architecture has expanded to support better search, some library functions, and multiple collaboration modes. As IT budgets get increasingly tied to a few vendors, savings in areas such as email should be evaluated.
