It is not possible to change the fields "receivedDateTime" and "sentDateTime" of email messages via Graph API. I'd like to change it without using workarounds.

Organizational Contacts make it possible to share contacts via Tenant to Tenant. The only decent way to key off source tenant is via adding ExternalDirectoryObjectId to a custom attribute. Please consider adding this to the Graph API. Graph is phenomenal, however, the details really matter when collaborating T2T.
#orgcontact #orgcontacts

The recipient

OR
Email address
https://docs.microsoft.com/en-us/graph/api/resources/emailaddress?view=graph-rest-1.0

has currently only the name and email but i would like to see the photo url (or other type of access to the picture)
I do see pictures of senders in outlook with email even when they are not in the contacts list.

Thx

I need to retrieve the last modified date of user profiles in Office 365 from the Graph API.

Could you please provide the endpoint similar to https://graph.microsoft.com/beta/me/?$select=createdDateTime

But have it be for the last time the user profile was modified by the user or admin, would be awesome for it to be https://graph.microsoft.com/beta/me/?$select=lastModifiedDateTime

Enable Microsoft Graph to access SharePoint security groups and members along with respective permissions like Read/Edit/Full Control.

When $expand=detectedApps is included on the /deviceManagement/managedDevices/{managedDeviceId} endpoint, all apps that have ever been installed on the device are returned. It would be great if only currently installed applications were returned to get an accurate representation of the applications on the device.

Example from a device in our environment, I only want to know the current version of the IME, not every version that's ever been installed:
Microsoft Intune Management Extension 1.15.109.0
Microsoft Intune Management Extension 1.24.114.0
Microsoft Intune Management Extension 1.15.102.0
Microsoft Intune Management Extension 1.23.103.0
Microsoft Intune Management Extension 1.22.107.0

In a hybrid environment where the local Active Directory is synced to the cloud, officeLocation should be writable through Graph API and synced back to the on-premise Active Directory. Thus would help us writing better Azure apps.

I need like the ability to query all tenants that a employees have been added to as a guest. This feature is required so customers can manage the tenant list used in the tenant restrictions feature.

According to https://docs.microsoft.com/en-us/graph/permissions-reference#remarks-23, now with permission:"User.readBasic.All" , only bleow properties would be visible:
- displayName
- givenName
- mail
- photo
- surname
- userPrincipalName

Which means "businessPhones" is not included.
So it means normal user (not admin) won't be able to view other users' business phones

Just suggest to include businessPhones in basic profile.

Most or all of the APIs related to Devices and Apps (Intune) only support Delegated Permissions. I see a lot of use-cases where I want to use Application Permissions instead of delegated to simplify and secure my integrations.

Ability to create shared mailboxes and manage their shared users.

In order to upload a (small) file and adjust the FileSystemInfo (eg. its LastModifiedDateTime property), currently 2 API calls are needed - 1 PUT + 1 PATCH.
Alternatively I can use the upload session and send the FileSystemInfo in the body. However using this approach, also 2 API calls are made.
In order to make uploading files as time efficient as possible, it would be great if there was a possibility to do this with just 1 API call

I would like to get all metadata of a users mailbox (especially the Exchange Mailbox Guid). There is currently neither a way to get the Exchange Mailbox Guid of a user by using Microsoft Graph, nor to get a user by posting the Exchange Mailbox Guid to Microsoft Graph.

Getting mail logs at /me/messages includes Teams chats, but previously Teams chats contained characters that could be identified as "IM" in the Subject.
Currently, it is set as blank, and it can not be identified as mail log or chat.
I want you to be able to identify chat logs.

The /v1.0/me/sendMail endpoint allows the user to specify custom internet message headers, but requires that each header begin with “X-“ or “x-“. Please relax this requirement so that we can add other common headers like “List-Unsubscribe” and "List-Unsubscribe-Post".

Provide an API to access time clock data from a Team's Shifts schedule, etc. Would be useful if there were a way to get this data integrated with payroll and other enterprise systems.

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.
