Last Logon is missing from the user objects in Azure! I'd like to be able to read the Last Logon information through the Graph API, to tell which users are actually logging in. But very surprisingly I can't find any such attribute!

Can we please please add this attribute to the user object?

While reviewing the O365 Preview API I was wondering what about Task-Management. Currently there are two systems for task management (Exchange and SharePoint). Would be great to see a roadmap for TaskManagement in the O365 Story and of course get an API to easily connect Apps to consume tasks. (No CSOM required just give us REST :D)

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.

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.

Please allow access to read and update user presence via API.

Through Graph, there is NO way to compose or quick send a message having, let's say, a 6 MB PDF brochure. I'm not asking for attachments of hundreds of MB, but the current limitation is a huge bug.
UploadSessions in the context of Messages could be a solution path to the inherent limitation of embedding base64 file content in a Json.

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.

It should not be necessary to require an admin consent to do Group read write operations through the graph API. There should be a permission for My Groups.

There is an adequate amount of client side Rest APIs for outlook, but nothing truly available on the admin side. Allowing API calls to create Online Rules and Connectors for example would (hopefully) be less error prone than manually invoking Powershell sessions, especially if rules and connectors need to be created en masse.

We would like to be able to set MFA for users from a custom application, by using Graph API or Azure AD SDK.

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?

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.

From https://docs.microsoft.com/en-us/graph/api/presence-get?view=graph-rest-beta, only Delegated (work or school account) is supported. Supporting application permission for presence calls is really helpful for enterprise usage.

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)

Facebook's GraphQL is the perfect API solution for the Microsoft Graph. I highly encourage you to implement this, since it would improve development for React apps.

We are integrating Microsoft Teams threaded chat into our product offering. Our users will interact with the channel-based chat using both the Microsoft Teams application and from within our application. To avoid polling, we would like to be able to subscribe to Microsoft Teams related events. Of interest are events related to new channel messages. We found similar subscriptions for files and email, but nothing related to Microsoft Teams.

See documentation for /subscription endpoints, Change notifications: "Use the Microsoft Graph API to get change notifications"

If want to hide o365 Group using HiddenFromAddressListsEnabled property from Outlook and discovery, the Graph still returns all "hided" Groups. Could you at least return that property with Groups data so we can hide certain Groups withing our apps?
