Choose hosted simplicity or customer-controlled deployment.
Cloud Hosted
Renfield Software hosts Exchange Sync Bridge on Amazon Web Services. Your Microsoft 365 administrator completes a one-time Microsoft approval, the license key is redeemed, and your IT admin updates the Exchange Web Services (EWS) settings in your existing software so it points to ESB.
Most customers should start here. There is no local relay server to install or maintain.
- Hosted ESB service operated by Renfield Software on Amazon Web Services.
- EWS-to-Graph translation for supported sync requests.
- One-time Microsoft 365 admin approval during onboarding.
- Enter your connection details during configuration.
- Monthly subscription billing.
- No local relay server to install.
Customer-Hosted
Customer-Hosted Exchange Sync Bridge uses the same basic Microsoft approval and licensing flow, but the relay Windows service is installed on a server in your own environment.
This option is intended for organizations that want direct control over the relay server, hosting environment, network path, operating system maintenance, and internal security controls.
- ESB Windows service installed on your server.
- EWS-to-Graph translation for supported sync requests.
- One-time Microsoft 365 admin approval during onboarding.
- Install API key for relay communication.
- Monthly subscription billing.
- Customer control over the relay environment.
Billing Details
- Prices are monthly subscription rates.
- No setup fees.
- No minimum term or binding contract.
- Each month, you will be automatically charged based on the number of users who have Exchange Sync enabled.
- You license a number of sync-enabled users. If you enable sync for more users than licensed, service continues uninterrupted. Your license count adjusts automatically at your next renewal.
- You can reduce your license count at any time by disabling users in the admin console; the change takes effect at your next renewal.
- Published pricing may not include taxes, implementation assistance, custom deployment work, or separately scoped isolation/security requirements.
- Customer-Hosted availability may depend on release timing and technical review.
Suspension and Reactivation
You can suspend monthly renewal at any time. Service continues until your next renewal date and then ends with no additional subscription charges.
