2. Typical Business Challenges Is our email fully compatible with all our remote and mobile employees’ personal devices? How can I reduce the complexities associated with managing our own email service? Are we spending too much IT budget on email hardware, security, licenses, upgrades and maintenance? Is our email platform meeting all regulatory compliance requirements for security, archiving and encryption? Since email is our primary communications method, how do I make sure its always up and running with my limited IT staff, and how do I provide backup protection? Is my email secure from virus attacks and spam? Does our email enable maximum employee productivity and collaboration?

For organizations under 10,000 seats, cloud email can be less expensive than on-premises email by about 25%. Complexity avoidance. Email is getting more complex as demands for mobility, redundancy, port 25 (SMTP) protection and storage are rapidly increasing.
