Free Busy Tool Troubleshooting
Verify calendar availability and diagnose configuration issues.
Free/Busy Testing Utility Flow
Overview
The Free/Busy testing utility is a diagnostic tool that enables administrators to verify calendar availability configurations and test free/busy lookups between different platforms. It's essential for validating coexistence setups between Office 365 and Google Workspace.
Primary Purpose
Use this tool to check "Free/busy and calendar availability between tenants" and diagnose any configuration issues before they affect end users.
Query Types
📧 Office 365 to Office 365
Direct availability queries within the same platform. Tests basic EWS connectivity and permissions.
🔄 Office 365 to Google
Cross-platform availability requests routed through Cloudiway. Tests full coexistence configuration.
Cross-Platform Query Flow
When querying across different systems, the free/busy request follows this path:
- 1
Initial Request
The test tool sends a free/busy query to Office 365
- 2
Address Space Lookup
Office 365 locates matching AvailabilityAddressSpaces configuration
- 3
Route to Cloudiway
Request is forwarded to the Cloudiway platform
- 4
Target System Query
Cloudiway queries the target system (e.g., Google Calendar)
- 5
Results Return
Free/busy information flows back through each layer to the tool
