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

"For me, the solution is very user-friendly. I've used it a long time and I know where everything is."
"The initial setup was straightforward and fast."
"The platform's most valuable feature is the mailbox roles."
"The email management system is very easy to set up, configure, and use."
"The most valuable feature of Microsoft Exchange is its ease of use."
"We have found it to be a stable solution. It is scalable and easy to install."
"Its technical implementation is quite good, it is stable and can be accessed through all kinds of devices, and it performs pretty well."
"Support is very good."
"The auto encryption of attachments is valuable."
"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."
 

Cons

"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."
"Microsoft Exchange could improve the archiving of emails and the performance."
"The setup is difficult so could be easier."
"I'd like the archiving process to be faster."
"They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks."
"Scalability probably is not proper."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"After 2022, users of Microsoft Exchange have to migrate mailboxes to Microsoft Exchange Online, and what I'd like to improve is for Microsoft to publish more on-premise versions for customers using Microsoft Exchange. Having more security is another room for improvement in the solution, particularly for mailboxes that develop the Exchange Edge rule to protect internal mailboxes. What I'd like to see from Microsoft Exchange in the future is for Microsoft to still update the latest, existing version which is 2022. I'd like Microsoft to still push more cumulative updates for Microsoft Exchange 2022."
"One improvement could be the integration between ProtonMail and Proton Pass, allowing sharing of specific secrets via email."
"I think it is good but I feel that only tech-savvy people use ProtonMail. It is not that popular among other people."
 

Pricing and Cost Advice

"Microsoft Exchange is an inexpensive application."
"It is not expensive."
"Its price is okay."
"It would be nice if it used less resources to run on-premise."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"Microsoft Exchange is a very well-priced solution."
"It's working very well. There is no problem, but the price is not the best."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
