There are still several features that are not available in the Microsoft Graph API but are available in Outlook REST API v2.0 and beta versions (https://docs.microsoft.com/en-us/outlook/rest/compare-graph-outlook). We would like to use these features but are concerned that the Outlook REST API will get deprecated soon and we invest time in something that won't be supported.
The documentation notes that its recommended to use the Microsoft Graph API but we could not find any page that reflects the Outlook REST API (v2.0, beta) roadmap / migration plan / the Outlook REST API lifecycle, can you elaborate?
