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.

Offers flexibility and cost-effectiveness with multiple service options but could improve support and mobile features
There are many things to consider about email management in Microsoft Exchange Online. The online management is good, the storage is sufficient, and we use most of the features such as the custom rules in Microsoft Exchange Online, which we cannot find in any other email solution. That is a very good option, as we have many options to create custom rules in Microsoft Exchange Online. Regarding security features in Microsoft Exchange Online, we also use Defender for Exchange which includes the basic Exchange Online protection that has spam and threat controls. The use of Defender is beneficial for our security. The flexibility of choosing plans in Microsoft Exchange Online is good. We have chosen the best plan for our use, including multiple licenses such as plan one and business basics, which leads us towards cost-effectiveness, and the pay-as-you-go option is more flexible. Microsoft Exchange Online is very scalable.
