KerioConnect Reviews Summary
Author infoRatingReview Summary
Senior Systems Tech/Admin at Samco Software Inc.5.0I've used KerioConnect for over 15 years; it's stable, easy to set up, and ideal for small to medium businesses, offering solid features like VPN and spam filtering, though lacking full integration like Gmail or Office 365.
Senior Systems Tech/Admin at Samco Software Inc.5.0We use KerioConnect as our mail server for multiple domains and clients. It's easy to maintain and manage, with robust security features such as anti-spam and antivirus. Creating domains and performing backups and restores is straightforward.
Information Technology Specialista at REMING CONSULT a.s.4.0I use KerioConnect for emails, calendars, and collaboration tools. It integrates with Outlook and Apple devices, offering good spam filtering and antivirus. While suitable for smaller organizations, larger ones need better server capacity and integration with MS Teams.
Lead Hand - Print Department at a marketing services firm with 11-50 employees4.5I find KerioConnect to be a secure and private mail server option for on-premise installations, offering control over email access and flexibility. However, it lacks integration with services like Google Docs and Google Calendar, but remains reliable and cost-effective.
Vice President at a manufacturing company with 51-200 employees2.5I find this corporate email solution simple and stable, but it's basic, lacks CRM integration, and user documentation is terrible. It's slow, crashes easily, and recovery is difficult. The user experience is neglected, rating 5/10.
IT at a manufacturing company with 11-50 employees3.0We use KerioConnect as a mail server integrated with Outlook for calendaring tasks. However, it lacks smooth integration with Microsoft 365 applications, prompting us to consider switching to Microsoft Exchange for improved workflow efficiency.
Senior Technician at Computers At Work4.5I use Kerio Connect for email applications due to its ActiveSync support, simplicity, and stability. Though native Outlook integration could improve, it outperformed Microsoft Exchange with its ease of maintenance, affordability, and minimal system resource requirements.
Lead Hand - Print Department at a marketing services firm with 11-50 employees4.5I highly rate Kerio Connect for its security, flexibility, and ease of use, appreciating its stability and support. My main concern is the lack of redundancy and a native cloud version for better scalability.
