findMeeting REST API does not support shared mailbox?

I'm building a bot using the MS Outlook Calendar REST APIs. I have a case where my user who is an executive assistant wants to create a meeting in the delegate mailbox she/he have access to. We are currently using findMeeting API to fetch the available for a set of users and this works perfectly for the logged in user. But, when we try to access the shared mailbox calendar using this API, it shows unsupported scenario. We do have Calendars.Shared .Read permissions.

/me/findMeeting - works 

/user/{sharedmailboxEmailId}/findMeeting - gives Unsupported Scenario error. Is this functionality not working? Couldn't find any document mentioning this. 

Alternative API getSchedule doesn't work in our case. 

 

Thanks in Advance!

    Hi RashmiRahul​!
    Hope you are doing well!

    Thank you so much for sharing your question with us — and for outlining your scenario so clearly.

    This seems to be relevant to what you're observing: the Outlook Calendar REST API you're using seems completely retired, and Microsoft officially decommissioned the v2.0 endpoints.

    When technologies reach deprecation, it’s common for certain operations to gradually stop working as the ongoing services evolve and new technologies are integrated, and some functionality may become limited or no longer available.

    For your reference, here are Microsoft’s official announcements on this deprecation:

    🔗 [DEPRECATED] Use the Outlook REST API (version 2.0) | Microsoft Learn
    🔗 Outlook REST API v2.0 and beta endpoints decommissioning


    To help you verify what is currently supported and explore alternative approaches, you can check the official Microsoft Graph support area:

    🔗Microsoft Graph | Support


    You can also use Microsoft Q&A — and simply select the product or technology area that best applies to your case‑scenario:

    🔗Microsoft Q&A | Microsoft Learn

    Both resources can help you confirm what is expected behavior today and what options may be available depending on your implementation.

    I hope this helps, and feel free to reach out to us anytime!

    Thanks a million!😊
