David Bloomer - PeerSpot reviewer
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.

AvinashLotke - PeerSpot reviewer
Offers good security with effective spam filtering but has update issues
Zoho is not just a traditional software-based company. It offers a wide range of APIs and other integration tools, including a CRM tool and various other products, so integration is not limited. Zoho has operations management and developers, making integration feasible with any system. Zoho is a cloud-based solution, meaning maintenance is managed by their system. They don't provide access to unauthorized persons. Zoho handles maintenance. Traditionally, we haven't recommended Zoho as extensively because we prefer systems we have thoroughly tested and can confidently endorse. We've deployed Zoho a few times with mixed success. In comparison, we've had more success with Google deployments, with higher implementation rates and ease, offering better revenue opportunities. Based on requirements, I might recommend Zoho, but for higher needs or better collaboration, I'd suggest Google, possibly combined with iSoft. If there is no other support, Google remains a strong recommendation. Overall, considering support, I rate the solution a six 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

"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."
"It's relatively simple to use."
"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."
"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."
"The user interface is good."
"The solution is easy to maintain, unlike Exchange. It's easy to create multiple domains and back up and restore if needed. It also has good security features like anti-spam and antivirus."
"The most valuable features are its ease of use, excellent pricing, and it is platform agnostic."
"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."
More KerioConnect pros
"The most valuable features of Zoho Mail are its security, integration with cloud storage, and wide range of features available. It integrates well with Outlook and mobile devices."
"Zoho gives you a set amount of free users, so you can use it until you reach the limit and see if it's something you want to adopt. I tried it and stuck with it. Since then, I've seen a lot of improvement. I already think it's top-notch, but I believe it will become one of the best in the world."
"Zoho Mail organizes your email well, and you can do a lot of things if you use other Zoho applications along with it."
"The solution has more security compared to other products. Zoho Mail comes with TLS and SSL. It has email-sharing features. It is an advanced product."
"Zoho Mail is a stable product."
"We can create email accounts for our customers."
"The notifications, scheduling, and meetings are all integrated."
"Zoho Mail is a cost-effective solution."

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."
"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"
"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."
"Having a native Outlook map integration would make Kerio Connect better."
"The search and archiving documentation capabilities need to be stronger."
"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 is stable as long as you use a strong password."
"I would like to see better support from their support team."
More KerioConnect cons
"We face some challenges in our current architecture with the introduction of data privacy regulations. When you are sending a calendar invite to a group of people for a meeting or an event, there is no structure for privacy. You can't hide all the contacts. Maybe that feature exists, but I don't know where it is."
"They have issues when they are rolling out updates"
"The solution's meeting plans and online virtual activity task list could be improved and made more seamless."
"The solution’s stability could be improved."
"Zoho Mail needs to add an IT system management feature."
"The initial setup of Zoho Mail can take some time because we have 30 to 35 users and we need to register each one. This can take one or two days to complete. The process could be better for administrators to register their users. If the setup interface was better in explaining the process it would be helpful to become more user-friendly."
"The interface isn't quite good. Everything looks a little low-quality."
"Zoho Mail is not as good as G Suite, which has integrated calendars."
More Zoho Mail cons
 

Pricing and Cost Advice

"The price of Kerio Connect is better when comparing it to others solutions."
"The pricing is about $3 per mailbox per month."
"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 solution is more affordable compared to other products. It is cheap."
"There is no license required to use Zoho Mail."
"The solution’s pricing is very reasonable."
"Zoho One has all 50 applications in it, and Zoho Mail is part of it. Zoho One is about 35 GBP per person per month. It includes Zoho Projects, Zoho Mail, Zoho CRM, and everything else."
"Zoho Mail is more cost-efficient than its competitors."
"If you have ten users, for Google, you'll pay $100. With Zoho Mail, you'll only pay $30 to $40."
"The solution is not costly."
"One of the reasons people use Zoho in Nigeria is because we can pay for it in Naira. It's very affordable already. For example, we can get Zoho Mail for somewhere between 1000 naira per user, which is less than one dollar. In my opinion, it's very affordable."
