Keep Outlook and Simplify Your Messaging Environment.

MailSite is for organizations that need business email and Outlook-compatible groupware but prefer to operate their own Windows-based messaging infrastructure instead of maintaining Exchange or moving every workflow to a cloud suite.

Prepare your 30-day evaluation

Register for a free trial, then use Downloads to request the evaluation key and obtain the matching MailSite 11 release. The issued key determines the edition, mailbox allowance, enabled features and expiry; verify those details before sizing your pilot. A desktop Outlook license is separate.

Before installation

Prepare a Windows test server that meets the chosen release’s requirements, administrator access, storage for mail and backups, DNS names and a trusted TLS certificate. Review the release notes and deployment guide for the exact prerequisites.

Validate the workflows you will migrate

  1. Record your client versions and required mail, calendar, contact, sharing and delegated workflows.
  2. Test representative mailboxes, external delivery, synchronization and access permissions using the client validation guide.
  3. Test backup restoration, cutover and rollback. Resolve failed acceptance checks before production migration.
