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.

The search and archiving documentation capabilities need to be stronger. The user documentation is ridiculous.

The connectivity with CRM is a significant issue here. We don't have a great way of getting these emails into CRM except by copying and pasting text.

In terms of connecting, we really need to connect this to a CRM system and there doesn't seem to be an excellent way to do it. It's very much a standalone product and the documentation does not make this easy.

It is not unstable. However, for example, I recently personally crashed it due to the fact that I had too many items in my folder. It turns out there's a hard limit as to how many files you can have in a folder, and so I personally ended up crashing the system. The result was my IT person is still trying to recover most of my email, even though we've gone through all the backup procedures and all this other stuff over the years. Once I crashed it, getting back access to my old emails has proved to be very difficult. This recovery stuff turns out to be very, very difficult.

The IT guys love this thing, however, from the user perspective, it's slow when it's cumbersome. Their whole sales pitch and documentation are focused on IT people running this thing. They don't seem to be particularly focused on the user experience.

Also, this thing is not updated from a feature set perspective. It's virtually the same as it was when we bought it. Now, under the covers, they've made lots of changes. However, from a user perspective, it's still pretty much the same.

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

We've been happy with the solution. It's worked for us so far so it's fine.

If they could integrate some sort of AI into the solution to make it more efficient, that would be interesting.

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.

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.

Kerio Connect runs on Windows Servers which I do not like because it is not secure and reliable. I would prefer to run it under Linux.

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

With the ubiquity of Microsoft Exchange, we don't see it being used very often.

I don't find it easy to use, but it might be because it is not my main technology.

It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case.
