At the moment it is not possible to get a list of groups that user can access. Getting the full list of groups (including private) is quite useless.

When the user receives an email, Microsoft Graph sends a notification like the following:
{
"value": [

{

  "subscriptionId":"<subscription_guid>",

  "subscriptionExpirationDateTime":"2016-03-19T22:11:09.952Z",

  "clientState":"secretClientValue",

  "changeType":"created",

  "resource":"users/{user_guid}@<tenant_guid>/messages/{long_id_string}",

  "resourceData":

  {

    "@odata.type":"#Microsoft.Graph.Message",

    "@odata.id":"Users/{user_guid}@<tenant_guid>/Messages/{long_id_string}",

    "@odata.etag":"W/\"CQAAABYAAADkrWGo7bouTKlsgTZMr9KwAAAUWRHf\"",

    "id":"<long_id_string>"

  }

}

]
}

If the returned result contains information about the folder id, it will be helpful to filter out unwanted information in some specific folders.

It is currently not possible to set the value of a Managed Metadata column on a SharePoint item using the Graph API.

Support for setting values on all standard SharePoint columns types is essential in the Graph API to drive adoption of this API. The following column types are currently not supported and have been raised in other UserVoice requests:

Picture and Hyperlink columns:

Currently there is support for startsWith and eq filters on proxyAddresses. However there is no way to search for proxyAddresses that endsWith or contains a string. E.g. finding users with a proxyAddress in a specific domain.

$filter=proxyAddresses/any(x:endsWith(x,'@acme.com'))

See this thread for more information: https://stackoverflow.com/questions/46588870/filtering-on-proxyaddresses-with-microsoft-graph-api-that-endswith-or-contains-a

Our organisation creates hundreds of sites for each project or client.

We rely on security to figure out who can do what. It would be nice to be able to get the list of sites available for a given account globally.

/sites returns an errors
/sites?search= returns stuff, but seems not be in the beta endpoinnt anymore

In order to, for example, filter users by a certain skill you cannot do only one REST call now.

From stackexchange:

"Filter on collection type properties is represented as below:

https://graph.microsoft.com/v1.0/users?$filter=skills/any(c:c eq 'Javascript')

However, filter on skills property is currently not supported. You can place a request in uservoice site."

I would like support for this /any command, specifically for skills but for all queries would be great too.

I am looking for the following equivalent: https://msdn.microsoft.com/en-us/library/office/dn641959(v=exchg.150).aspx - "How to: Add and remove delegates by using EWS in Exchange". (delegating access to calendar / mails /... is quite common in company settings)

We need to get the content of the user's acitvity stream in Teams. "All notifications" and "unread notifications" would be really helpful to create alternative visualizations.

I would like to be notified when tasks are created, updated or deleted in the graph api change notifications. Alternatively delta queries would be helpful in creating a standup-feed of information that has changed since the last meeting.

Allow developers/tenant admins to configure apps so that schema extension properties (added to users through Microsoft Graph) can show up as claims in id and access tokens

Planner tasks, buckets and plans are apparently not accessible using client credentials flow (app only).

I can access them using code flow authentication, but that's not my requirement (internal web service).

Everything else seems to work - it's just the planner stuff that doesn't (401 unauthorized).

Is there a workaround that doesn't require a user to log in?

We need the App Authentication model to be able to retrieve conversations for unified groups. This isn't a user specific call so I'm unsure why it's not currently possible?

When using the Graph API to interrogate Planner Plans & Tasks, I would like to receive a URL as part of the json, to open the particular plan / task in a browser window.

Right now you cannot achieve "conversations" view in a mail folder using REST API with one request.

A workaround can be found here http://stackoverflow.com/questions/41161515/best-way-to-achieve-conversation-view-for-mail-folder-using-outlook-rest-api

but it is quite slow and not very efficient. Conversations view is the primary view of many mail client but is not achivable (easily) with REST API

It seems that Outlook REST APIs is providing new scopes and the possibility to request the shared mailboxes. See this question on StackOverflow http://stackoverflow.com/questions/38616499/what-is-the-purpose-of-the-new-read-user-and-shared-mail-delegated-scope-in-az/38626322?noredirect=1#comment64649553_38626322

The problem now lies in the fact that we cannot "discover" the shared mailbox for the end user. It means that you cannot create an application that show all the shared mailboxes for an end-user because we do not know the name/id for them.

When using the 'classic' Get-MSOLUser, the -Domain parameter can be used to filter users by an equivalent "endswith(userPrincipalName, "domain.blah") filter, but this is not possible with the Graph API or the AzureAD v2 PowerShell module.

I'm sending email on behalf of logged-in user in my app.
I would like to ability to include email signature defined in the user's mail settings.

When requesting the children of a OneDrive for Business folder through the Microsoft Graph API, adding a $filter query parameter is currently not supported.

Repro:
https://graph.microsoft.com/v1.0/me/drive/root/children?$filter=folder ne null

Result:
{
"error": {

"code": "notSupported",

"message": "The request is not supported by the system.",

"innerError": {

  "request-id": "7643cbce-1934-4b46-8bd9-e81cf412e810",

  "date": "2016-10-21T08:38:15"

}

}
}

Please add support for filtering.
