Hi everyone,
For those looking for a way to connect Microsoft Exchange Server on-premises to modern AI models without waiting for future Microsoft updates, we have developed a solution.
Postgate AI provides a hosted MCP server (Model Context Protocol) that connects directly to your on-prem Exchange Server.
Key features:
- Compatibility: Works with Exchange Server SE, 2019, 2016, and hybrid environments via EWS.
- Security: Uses delegated per-user permissions instead of a service account or impersonation.
- Flexibility: Compatible with Claude, ChatGPT, and any MCP-capable AI client.
- Data Privacy: Operated in Germany under a GDPR data processing agreement (DPA). Message content is neither stored nor logged.
