Reliable email service has supported consistent communication and improved user training

I do use Cisco Secure Email, Grafis, and Proofpoint Email Protection when needed, but we were using Proofpoint before, and we are no longer using it. I am currently using Microsoft Exchange as our email solution. We are a client of Microsoft; there is no partnership between my company and Microsoft. My experience with Microsoft Exchange is as good as the generic email. I do not use Microsoft Exchange to synchronize emails across devices, and it is not part of my workflow. The protocols I mostly use with Microsoft Exchange for integration are SMTP. I do not use the shared calendars feature in Microsoft Exchange. Data loss prevention is something we are not really using or utilizing at the moment. My overall review rating for Microsoft Exchange is 8.
