Executive SummaryUpdated on Jun 29, 2025

Mimecast Mailbox Continuity and KerioConnect compete in the email platform space. Mimecast Mailbox Continuity has an edge due to its advanced continuity features, crucial for reducing downtime, whereas KerioConnect is favored for its affordability and simplicity.

Features: Mimecast Mailbox Continuity ensures robust email continuity with real-time alerts, provides extensive security including URL and attachment protection, and features a Large File Send option for substantial attachments. KerioConnect offers simplicity in use, built-in ActiveSync support for device integration, and security with on-premise server installations ensuring privacy without cloud reliance.

Room for Improvement: Mimecast Mailbox Continuity may benefit from simplifying its initial setup process and offering more competitive pricing options. Although already equipped with advanced features, improving user interface intuitiveness could enhance user experience. KerioConnect could improve by expanding its feature set to compete with higher-tier solutions, improving cloud integration capabilities, and strengthening customer support accessibility to match larger competitors.

Ease of Deployment and Customer Service: KerioConnect offers an easy installation process, requiring minimal configuration and allowing quick deployment without the need for specialized IT support. It is also praised for its straightforward and responsive customer service.

Lightweight, simple, and robust; easy to maintain and doesn't require a lot of system resources to run

Kerio Connect does as advertised, so there are no real issues with the product itself. It's developed regularly, so there are constant updates. Possibly, the support and development have lessened since they've sold the company, but as far as the product itself is concerned, there isn't anything that I would suggest needs improvement. If I'm being picky, Kerio Connect uses a proprietary, mappy atom for Outlook, and it would be nice if they used a native mappy connection instead, but that's the only additional feature that I would like to see in its next release. If they have native Outlook map integration, that would be great, but other than that, it's got all the functions that I think a mail server should have.

Provides peace of mind and expands well but needs a better interface

It's a hosted solution. I'm not sure which version of the solution Im on at this time. I would advise others to research all the options out there and see what the best fit is. We started this mailbox continuity project before we moved to Office 365. And now that we've moved to Office 365, we kind of don't need this piece of technology in the same way that we used to need it when we had an on-prem exchange. Therefore, make sure that you actually need it and then research to find the best options. Overall, I would rate the solution seven out of ten.

Quotes from Members

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

Pros

"The user interface is good."

"What I like most about Kerio Connect is that it supports ActiveSync, and that is its most critical feature. The solution is also a nice, simple, robust, and stable mail server."

"Kerio Connect is secure, flexible, and easy to control from the user interface. It has many security features able to be controlled from one place, such as anti-spam. I have found it very convenient. Additionally, you can analyze log files and share folders which is helpful."

"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."

"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."

"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."

"It's relatively simple to use."

"KerioConnect has integration with 365. We can use Outlook, which has its client and can be used with Apple devices. It integrates with the App Store and Microsoft Office. It has a smart router. The spam filtering and antivirus are good."

More KerioConnect pros

"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."

"The Large File Send feature comes in handy when you have to send fairly large attachments."

"It has all the features required for distribution, such as the ability to mail."

"Mimecast has some good support services in place."

"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."

"We're now certain business-critical mail is perfectly protected in multiple ways."

Cons

"We are considering switching to Microsoft Exchange. One reason is that it doesn't improve our workflow and doesn't integrate well with Microsoft 365 applications."

"KerioConnect is stable as long as you use a strong password."

"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow. They could make it faster to get onto the web interface without so much load time. It's just slow with Outlook, however, for some reason."

"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."

"I would like to see better support from their support team."

"The solution could improve the redundancy because we only have one copy of the Kerio Connect server on our hardware. The next step for us is to move to the cloud and if Kerio does not have a cloud version available they should release one"

"You cannot integrate with other services like Google Docs, Google Assistant, Google Calendar, etc."

"Having a native Outlook map integration would make Kerio Connect better."

More KerioConnect cons

"The solution is expensive in comparison to similar solutions."

"Technical support has been slower than it was in the past, likely due to the pandemic."

"The price of the solution is expensive. It can improve by reducing the price."

"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."

"The interface isn't the best. How everything works on the back end is confusing."

Pricing and Cost Advice

"KerioConnect has a first-time cost and yearly subscription. It is not expensive."

"The solution's pricing depends on how long you plan to keep it because you pay on a per-year basis. You might have a one-time setup cost for something like Microsoft Exchange or a Linux mail server. I'd say this solution is expensive on a per-year basis, almost 2000-3000 dollars annually. It doesn't seem to pay off yet, so we're considering switching to another product."

"The pricing is about $3 per mailbox per month."

"The price of Kerio Connect is better when comparing it to others solutions."

"The price of Mimecast Mailbox Continuity is expensive."

"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
