For OneDrive drives, when a public link is added to an item, the delta link will return that item. This doesn't happen for Sharepoint drives (document libraries). For consistency the behavior should be the same.

Since suppressing a guest user from the Azure AD won't suppress it from all the sites where he has permissions/shared documents we must identify those sites.

We need to know all the sites on the tenant where the user has shared access to some child elements.

The Sharepoint part of the graph api is really small.

It is currently impossible to filter list items by their title or any other field via the Graph API.
Adding support for list items filtering on fields would help query list items.
Example of query
https://graph.microsoft.com/v1.0/sites/{siteId}/lists/{listId}/items/?$expand=fields($filter= Title eq 'value')

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

When I make the following graph call:

https://graph.microsoft.com/v1.0/me

As an account authenticated against a tenant I'm a guest in, I get the user details for that target tenant.

The account has access to a SharePoint site collection via the same B2B identity. When I make the following sites call:

https://graph.microsoft.com/v1.0/sites/tenant.sharepoint.com,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx,yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy

where the two guids reference the site the account has access to, I'd like to see the same data returned as if I'd made the graph call from an acount homed in the site's tenant.

At present, the lastModifiedDateTime for Site objects doesn't seem to reflect the datetime that a non-system user modified the site. This might be worth returning to aid in governance queries, similar to how the REST API handles it.

Although it's possible to get all members using Group API, it only works for modern sites or group connected site. Add directly "list all users for a site" will greatly help many business scenarios.

There is too much data in the List, such as more than 5000. When using $filter for conditional query, if the result of the known query is very large, for example, the query should return 5000+ records, then the query will report an error.

"error": {

    "code": "activityLimitReached",

    "message": "The application or user has been throttled.",

    "innerError": {

        "request-id": "e6fca4dc-bf11-48d5-8c80-ef32ef8e6926",

        "date": "2019-01-17T05:46:35"

    }

Following this StackOverflow post, I suggest this feature.
Allow filter and order for SharePoint lists queries through Microsoft Graph API.

Provide an API to retrieve the custom formattings for views in a SharePoint list?

Provide Graph API to retrieving column formatting for a column of a SharePoint List

Today the Teams API under the Microsoft Graph doesn't support SharePoint (and PowerBI) Teams tab creation. https://docs.microsoft.com/en-us/graph/teams-configuring-builtin-tabs#sharepoint-page-and-list-tabs
This is an important gap for Teams provisioning and it would be interesting to have that capability

On beta version -> Get page list. Json should provide webpart for image. Current version is only id, instanceId. I suggest provide imageSource or "uniqueid"

Document sets are pretty handy when it comes to document management practices and governance. It would be useful to support creating document sets via the Graph API

Site ID isn't returned for all the site collections discovery. When we had quries for 24 sitees - we got the Site ID for 8 and didnt get the remaining 14
Do we know ifthere are any restriction to certain type of sites for not returning the Site ID

Microsoft Graph allows us to search individual sites

e.g.

https://graph.microsoft.com/v1.0/sites/mydevspsite.sharepoint.com,siteid/drive/root/search(q='cheese')

The SharePoint REST api allows us to search across all sites

e.g.

https://mydevspsite.sharepoint.com/_api/search/query?querytext=%27chicken%27

It would be extremely useful to be able to perform the search all sites call directly from the MS Graph.

The endpoint for list items only return item with
ContentType "Message". I need an endpoint that returns both ContentType "Message" and ContentType "Discussion"
