  1. Enable Calendar Sharing

    Currently there is no API to share calendar with another in user. This is possible with O365 WebApp and Outlook client. Please enable this through API also

  3. Update Event needs the option to send only to added or deleted attendees

    Update Event should include a Boolean to enable an option to 'send notifications to added or deleted attendees only' that will stop notifications going out to all meeting attendees when the only property that has been modified is attendees. This is causing an issue where people are getting dozens of unnecessary notifications when a meeting owner adds or removes attendees using the API or via a connector (ex. Flow).

  4. Write permission on user calendars

    Would be great if we were able to give 3rd party applications just the right to Write in to the users calendar without being able to read the users meetings. For this a simple free-busy permission would be great as well.

    Then we can have calendar functionality without giving away data to other vendors.
    As calendars can contain sensitive information that you are not in control over (you could get an meeting invite from someone else with sensitive information).

  5. auditing

    Graph API : How can we Audit mailbox access by Application Permission AD apps that have been granted admin consent. We are logging client-request-id, request-id, timestamp and x-ms-ags-diagnostic from the HTTP response headers of Graph but we have to reach microsoft to get details of these calls.

    For an Azure AD/Office 365 admin, Graph API audit logs should be available in Security and Compliance section.

  7. Better support recurring calendar event exceptions

    When retrieving a list of occurrences for a recurring event (/me/events/{id}/instances), the result is lacking some critical data regarding exceptions. In particular, we need to know the original date/time of an exception, so that we can match it with the original occurrence. Also, there is no information at all about deleted occurrences.

  9. When an upcoming event is starting soon subscription

    Microsoft Flow and Logic Apps currently support the OnUpcomingEvents endpoint. Is it possible to access this functionality from an application (not Logic App or Power App) registered in the Azure portal?

    I am building an integration in our application, and want to trigger some business logic based on when an event is about to begin, but relying on Flow etc is not an option. Can this be accomplished through some sort of subscription?

    Some info I found on the endpoint:

  10. Allow cancelling calendar events via API

    I need to cancel existing events via API.

    The current stable version of Graph API does not allow to cancel any existing event, and you cannot update the isCancelled property, so the only option is to delete the event.

    The cancel method is in the API beta version, but is seems it takes YEARS for the beta versions to be published as stable.

  11. Allow more control over fields returned in the Calendar API calls

    Allow administrators to filter which fields can be returned per endpoint. Our end client is concerned that even though we are filtering the results on our side we still have access to Calendars.Read and technically have access to read meeting subjects, etc. Is there any way in Office365 or the Graph API that our end client can apply more granular permissions to filter which fields we have access to?

    My particular example is using the CalendarView endpoint to retrieve a users appointments for a specific time period. While calling the endpoint we are passing $select=start,end,showAs. Our end client does not…

  13. Enable Search for Calendar API

    Messages API endpoint allows a query parameter $search to filter messages based on text. The same for Calendar API would be tremendously useful.

  15. Calendar Create userImpersonation functionality to replace EWS API feature

    We have a pair of business workflows which have been for 10+ years been creating calendar items via the deprecated EWS API's. When moving to Exchange Online there is no like functionality.

    Scenario 1) Corporate calendar for all employees - all-day calendar items that are free with no notifications

    Scenario 2) faculty schedules are exported out of our ERP system and loaded via EWS API's to the faculty member calendars.

  17. Create Microsoft Graph Subscriptions for a shared calendar with delegated user permissions

    The MS Graph documentation for subscriptions (webhooks) implies that it is possible to create a subscription on a shared calendar with delegated user permissions (not app-only). Currently, this works only with app-only permissions.

    I would very much appreciate to create subscriptions to shared calendars also with delegated user permissions.

  18. Webhook notification for Out Of Office

    Would like to get a notification (web hook) for when a users OOO status changes. Ideally would like to display OOO status in our 3rd party app. Today we poll at a regular interval, but would like to be notified of OOO changes.

  19. Make findMeetingTimes aware of the 'Working Elsewhere' status

    findMeetingTimes does not consider attendee events categorised as 'Working Elsewhere' as unavailable for meetings.

    This makes scheduling face-to-face meetings when some attendees may be working offsite impractical.

    Please provide an option for findMeetingTimes to consider 'Working Elsewhere' as unavailable.

  20. Add Pagination to the findRooms API, to get past the limit of 100 rooms

    The /findRooms API states: "You can get up to the first 100 rooms in the tenant". Could you please add standard Pagination, to get past this limit?

    I tried /findRooms?$top=1000&$count=true but I am not able to make these query parameters work. In addition, I now understand that the API doesn't currently support things like $top or $skip.
