During the trial, test the “Backup to cloud” feature (SFTP/Amazon S3). Many admins miss that and regret it later. Reviewed on: A clean Ubuntu 22.04 VM with 4GB RAM, hosting 15 active test users for 25 days. No crashes, no data loss, no surprise license expirations.
Out of the box, the trial’s SpamAssassin scores are conservative. Expect to whitelist/blacklist for a week. The trial lets you learn this, but don’t expect perfection on day one.

Kerio Connect doesn’t have native active-passive clustering. The trial will remind you of this. If HA is a deal-breaker, the trial helps you discover that early.
The trial is the exact same binary as the paid version. You can stress-test it with real users, large attachments (up to 2GB per email), and hundreds of folders. Performance is snappy—even on modest hardware (4GB RAM, 2 vCPUs).
ActiveSync setup is trivial: Server address → username → password. No complex autodiscover DNS headaches during testing (you can use IP or hostname with self-signed SSL).
