  1. [GraphAPI/Office 365 Rest API] please add support for notifications/subscription on Exchange RoomMailBox in delegated API permissions mode

    GraphAPI/Office 365 Rest API, please add support for notifications/subscription on Exchange RoomMailBox in delegated mode.

    In delegated API permission mode, we are able to get events from RoomMailBox calendar but not subscribe for notifications (webhooks) on events changes
    Each time we tried to create notification channel we got :
    "error": {

      "code": "ExtensionError",
    
    "message": "Operation: Create; Exception: [Status Code: Forbidden; Reason: Access is denied. Check credentials and try again.]",
    "innerError": {
    "request-id": "XXXXXXXXXXXXXXXX",
    "date": "XXXXXXXXXXXXX"
    }
    }

    Moreover, in Exchange, we have full access on RoomMailBox by using user account we used on delegated mode (user account impersonated). Push notifications…

  2. Add Calendars.ReadBasic minimum permission for getSchedule

    getSchedule and list events require the same permission - Calendars.Read. This is too broad for getSchedule, allows the caller to list events, including the event subject/body.

    Create a new permission: Calendars.ReadBasic. Use it as minimum permission to retrieve free/busy info only, which is sufficient to determine availability and scheduling meetings.

    Exchange Calendar permissions and sharing policies have this. https://docs.microsoft.com/en-us/exchange/sharing/sharing-policies/sharing-policies.

  3. Add ability to add/edit/update Teams meeting roles from the Graph API

    Using the graph API you can create a new Group Event /groups/{id}/events/{id} however because it's in a group, you're unable to set the Organizer of the event because it will always be the group it's self.

    This leaves the only 2 people that can change the 'meeting options' (via a link in the calendar appointment)
    - Organizer - This is the group itself (the group doesn't have a login - so it's not an option)
    - The Owner - The account who run the API call to create the event. If this is a service account, then this isn't an…

  4. Create Event should include a Boolean to enable an option to 'send notifications to attendees'

    I need to restore events from a user calendar through MS Graph API without notification sent to the attendees. The problem is that when the event is created, it automatically sends an email to all attendees, whether it's old or new event. I want to just create the event without any email send. I also tried to add a ResponseRequested=false and responseStatus=None properties, but it's do nothing.
    I'm unable to find any option how to control this. Create Event should include a Boolean to enable an option to 'send notifications to attendees' if its false then it will not send…

  5. Update this and following events in Microsoft Graph API Event

    We are integrating Microsoft Graph API events with our Application. We noticed that the Graph API covers almost all basic functionalities for a single event like create, updates, delete, respond to an event. But when it comes to recurring events, it lacks some basic functionalities like update this and following recurring events. 

    For example, If I have created a recurring event A from 1st July to 15th July at 10 pm to 11 pm and if I wanted to update the event A timing, from 9th July onwards till the end of recurrence at 9 am to 10 am, I don't have…

  8. 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. Expose iCalUId on deleted calendar events

    For integrations that cannot rely on the opaque ID alone, as iCalUId is very different (uniquely identifies the same event on EVERY calendar, not just the user's calendar)

  11. We would like a webhook to subscribe to a change on a users/mailboxsetting from outlook

    we would like to be notified via a webhook when a user switches on or off their out off office status in outlook. We have a Bot that allows users to switch on their out of office via graphAPI , but what if a user switches on or off their out of office from outlook? the Bot will never know about this and we would like to cover both ends of this to make sure to keep out of office statuses in sync.

  13. POST /users/{id | userPrincipalName}/events ignores booking lead time

    When creating an event the Booking Options Maximum booking lead time (days) value is ignored unless the autoresponder gets the request. If the event is directly created against the resource via Graph it is accepted.

  15. Filtering events by schema extensions

    We are looking for a good way to apply a few basic custom fields to calendar events so that we can tie them to resources that exist within our application. Schema extensions seem like they could fit the need, but a known limitation mentioned in the documentation is that filtering on Outlook entity types is not supported: https://docs.microsoft.com/en-us/graph/known-issues?context=graph%2Fapi%2F1.0&view=graph-rest-1.0#filtering-on-schema-extension-properties-not-supported-on-all-entity-types.

    Is it possible that this could be supported in the future? Or do we need to look for a workaround?

    Note: We noticed that the "singleValueLegacyExtendedProperty" fits this description, but since this is a "Legacy" feature, I'm assuming we can expect…

  16. Always send meeting update to resources(like room)

    Currently, in the calendar of the room an event is created based on Email sent by the organiser while creating meeting
    in his calendar with selected room.

    It does update the event in the room calendar when name or time range of the event is changed,
    but it doesn't when new users are added or old ones are deleted from the meeting.

    Exchange treats resources (including rooms) like attendees and only send them updates when the changes are linked with them.

    Personally, I think that meeting updates should be always sent to resources.

  18. 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).

  19. A person's Out of Office Status/Message should be added to Calendar

    It does not make sense to have to look at a person Mailboxsettings to know if they are showing an out of office message and for how long.

    The details of whether a person is in or out of the office should be added to a user's Calendar properties (for example getSchedule) as it appears logical to me to get this information when querying a person's schedule/status/calendar.

    I have also often seen that people have an out of office notification but have nothing in their calendar.

  20. Allow granting access to a user's calendar without sending a sharing invitation by email

    It is currently possible (although not documented) to POST a CalendarPermission object to https://graph.microsoft.com/beta/users/{id}/calendar/calendarPermissions. This creates, rather than updates, a CalendarPermission entry.

    The issue is that the user or group that receives the permissions, also receives a sharing invitation by email. There should at least be an option to not send sharing invitations - this can be highly impractical if you grant access to security groups with many members.
