What are the availability / free-busy limits?

These apply to API V3 also. Microsoft does not support meetings less than 30 minute duration for EWS accounts.

As a developer it is important to build limits into your models for the endpoints, the following applies when passing emails attribute (fetches from provider)in the endpoint

Supported providers:

• GMail
• Microsoft

Min Meeting Duration:

• Microsoft 30 minutes
• GMail 5 minutes

Max Meeting Duration:

• No Max

Max forward lookup - how far in the future can you check for availability 

• Microsoft 62 days
• Gmail 90 days

If you use calendar_id then these limits do not apply and you can schedule meetings of 5 minutes across providers. See Free-busy does not return the expected results

In API V3: The /availability endpoint is 90 days for all supported providers. /free-busy remains provider limited.
