Sorting a library's items by lastModifiedDateTime is throwing an error. This should supported.

There are throttling limits given for outlook and teams at the link https://docs.microsoft.com/en-us/graph/throttling.
What is the limit after which the throttling starts for graph API calls for SharePoint.

SharePoint decided not to publish their throttling limits see the following abstract: https://docs.microsoft.com/en-us/sharepoint/dev/general-development/how-to-avoid-getting-throttled-or-blocked-in-sharepoint-online#why-cant-you-just-tell-me-the-exact-throttling-limits.

It will be really useful to get the limits for SharePoint too.

With SharePoint Online REST API we can work with role assignments and role definitions. So we want to do the same things with MS Graph API.

There is no way to retrieve this info without scraping the actual web page. If there is, could you please point me in the right direction. This should also be added to the Management Activity API so all content (edits/deletes) can be capture for compliance reasons.

Get total count of site collections

Allow users to attach files to a listitem and to retrieve it.

As for today it's not possible to access attachments in the Sharepoint list item and this requires to use REST API.

Allow us to manage permissions on ListItems in the same way we can manage permissions on /Drives/{Drive ID}/items/{item ID}/permissions.

Use case: List contains potentially sensitive items that we want to restrict to users based on the contents of a people picker column (not necessarily the creator/modifier).

Using Graph API, we can currently access and update values in existing columns for a given item, or supply values for existing fields/columns when we upload files. However, there doesn't appear to be functionality in place for creation of a new SharePoint list column. This would be useful in the case of a program that checks for the presence of a column before adding to it, and if there is no column present, it creates it.

Currently sitepage apis versioning is in beta version, the plan for this to be GA?

Ability to connect with newly released Site Usage Data Update, in particular the Average Time Spent Per User, so it can be pulled via Graph

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')

Add to MS Graph API analogues of the SharePoint Online REST API methods:
1) /api/web/siteusers
2) /api/web/sitegroups

Today, to get items for a given list, I need to do it in 3 calls and 3 statements:
1. Get the Site then take the site ID

2. Get the lists for the site (there is no filter) then filter by name.
3. Get the items and fields.

Instead, there should be a call that takes the list's URL as parameter "https://contoso.sharepoint.com/sites/HR/Lists/MyList" for example.
The graph processor should be able to dicier the site and list and just give the item like it does now.
There will be 1/3 the network traffic.

As it's impossible (https://github.com/pnp/pnpjs/issues/457) to create custom Content Types using the SharePoint Rest API, a Graph endpoint is needed.

Currently webhooks support only events that regard list items. I would like to see supprort for field events (such as field added, removed, renamed) and also site level ones, when lists or content types change.

Enable the $search OData parameter to search within SharePoint Online sites, document libraries, etc.

https://graph.microsoft.com/v1.0/sites/{siteId}/lists/{listId}/items?$search="whatever"

If this is not intended as the new Search API is growing, I'd suggest that Application Permission Type (application token credentials) are allowed in this endpoint.

Support /delta for lists/listItems

Currently, I cannot discover members & owners of a communication site via graph api.
I think graph api should expose api to retrieving members, owners of communication sites. Of course, I can discover by using SharePoint rest API, but I don't want to change
Note: for a team site, I can get members, owners by using group api.
