Microsoft 365 & Exchange: messaging consulting from Switzerland
I am Rafael Pfister, independent messaging specialist and founder of Adeptio GmbH. My field is the email infrastructure around Microsoft 365: Exchange Online, Exchange Hybrid, mail routing and the operations behind it. Project-based, without intermediaries, remote or on site in German-speaking Switzerland.
- Exchange Online
- Exchange Hybrid
- Mail Flow
- Connectors
- Transport Rules
- PowerShell
- Switzerland
Typical starting points
The hybrid environment works, but nobody remembers exactly why. An audit demands a hardened mail infrastructure. The certificate on the hybrid connector is about to expire and the documentation is missing. Or a new gateway has to be inserted into a grown mail flow without anything getting stuck. In these situations I start by establishing the actual state before anything is changed: connectors, transport rules, accepted domains, submitting systems.
Services
- Architecture reviewInventory of mail routing, connectors, transport rules and submitting systems, with prioritised measures instead of finding lists.
- Hybrid operations and hardeningHybrid connectors, certificate rollovers, internal/external classification, locking down the on-premises edge when MX points to the cloud.
- Rebuilding mail routingInserting or replacing gateways, routing changes with a rollback plan, rounding up direct-send sources.
- Operations automationPowerShell evaluations for message tracking, connector inventory and recurring operational tasks.

- Documentation and handoverYour operations team can maintain the result without me.
Real-world examples
- Analyzing Exchange mail flow: message tracking, SMTP logs and receive connectors, systematically.
