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.

Trust and anonymity play a key role in secure communications
I am uncertain about the two-factor authentication feature. I have had integrations with other Proton services and have used Proton VPN once, though it has limited features. Simple Mail, which was acquired by ProtonMail, has been very useful for me. The pricing is moderate. I have not used any paid services from ProtonMail. It is not very costly, but I have not used any premium services. I am a customer of ProtonMail. I would rate ProtonMail an eight out of ten due to their transparency and the utility of their simple login feature. My job and company name should remain hidden.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of the most valuable features of Microsoft Exchange is its security."
"I like the logistics and Microsoft protocol of reaching Outlook anywhere; it's a user-friendly product."
"Microsoft Exchange is stable."
"The setup program is straightforward, but there are hiccups when you try to move it between computers."
"This solution has improved the collaboration between our organization and our partners and contractors."
"The platform's most valuable feature is the mailbox roles."
"The most valuable feature of Microsoft Exchange is its communication capabilities."
"The most valuable features are that you can exchange information, tasks, attachments, and enhance the process in a short amount of time."
"ProtonMail is cost-effective for encrypted mailing, offering extensive features and customization, especially if you want to provide your own hashing and keys."
"What I appreciate most about ProtonMail is that they are trusted, which is why I choose them."
"The auto encryption of attachments is valuable."
 

Cons

"I do not have any notes for improvement."
"The solution should be easier to deploy."
"Sometimes we don't get support quickly enough - for example, if there's some global hacker attack, we don't get served as quickly. The skills of the technical staff can also vary, and Microsoft could perhaps improve their training."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"The issue with Exchange has always been storage."
"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."
"Exchange took time to be deployed. It requires extensive configuration and setting up servers and managing internal network access."
"The solution is stable, but it could improve. It's crashing if there is a big mail database. The Zimbra solution is better in this area."
"I think it is good but I feel that only tech-savvy people use ProtonMail. It is not that popular among other people."
"One improvement could be the integration between ProtonMail and Proton Pass, allowing sharing of specific secrets via email."
 

Pricing and Cost Advice

"The product pricing is reasonable if you utilize its full suite of features."
"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"It's a little bit expensive."
"It is not expensive."
"Licensing fees are paid monthly."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
