"Kerio Connect is a great option"
4/5
What do you like best about Kerio Connect?

The upside of Kerio Connect is the ability to be able to access the back end of the service. It is helpful to be able to check on issues our customers may be having. It is very intuitive and flexible. Review collected by and hosted on G2.com.

What do you dislike about Kerio Connect?

Unfortunately, Kerio Connect does not integrate well with other systems. If you need to tie into calendars or other systems using an API, the system can be a bit buggy. Review collected by and hosted on G2.com.

"Kerio has been going downhill for a while now. (This review is of the cloud version of Kerio)"
0/5
What do you like best about Kerio Connect?

Easy integration with multiple platforms. When logging into the webmail interface, there's a link for automatically downloading and installing profiles to your specific device. Review collected by and hosted on G2.com.

What do you dislike about Kerio Connect?

The admin console is very slow and buggy. Using Chrome on a Mac, the email user list shows the same user address for every entry.

Most recently, a bug in their system prevented us from paying invoices online. This was a problem because we couldn't add a new user without paying the pro-rated invoice. It took more than a week for them to allow the new user to be added without paying the invoice. It then took another several weeks before they solved the payment problem.

The spam filter/interface is unwieldy. Also, I often find the spam notification emails IN THE SPAM FOLDER.

Periodically emails just don't go through and no warning is given. That's fun. Review collected by and hosted on G2.com.

What do you dislike about Kerio Connect?

My email has been out for six hours and no one seems to know what's going on. They are not even close to helping us. Review collected by and hosted on G2.com.
