You want fully managed cloud email or need Exchange-level scale. Kerio Connect has a native Outlook MAPI connector

Mac users can use Outlook for Mac with EWS, but the full MAPI connector (for shared calendars free/busy) is Windows-only. That’s a Kerio limitation, not a trial one. ActiveSync setup is trivial: Server address → username

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).

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.
