The short version
- Each has a real cost: Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation; Outlook Calendar offline support limited to only past 30 days of events, older events unavailable
- They diverge on capability: Docker covers Container runtime, Outlook Calendar covers Meeting scheduling.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Docker
- Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
- Daemon socket exposure grants full root access to the host if compromised
- Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
- Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
- Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments
Outlook Calendar
- Offline support limited to only past 30 days of events, older events unavailable
- Shared calendars and group calendars not available offline
- Cached Exchange Mode issues can limit available offline data
- Occasional sync conflicts when coming back online
