The transactionId property has been introduced into Create Event API.
https://docs.microsoft.com/en-us/graph/api/user-post-events?view=graph-rest-1.0&tabs=http#example-1-create-an-event-in-the-specified-time-zone-and-assign-the-event-an-optional-transactionid-value

That would be great if the similar function is introduced into Update Event API. Sometimes our application need to do unnecessary retries due to network issue or Microsoft Graph issue, and it generates unnecessary event update messages.

When editing my profile on my company Sharepoint, I see that there is the section "Custom properties" where I can specify Division, Report To, My Bio.

These information is then shown in the User profile view in MS Delve.

I would like to extract these information, using the Graph API on .NET.
I have taken a look at the documentation of Users API in v1.0 and beta, but there is no mention of custom properties.
I have also looked the new Profile API (Preview) but again there is no mention either.

Please provide the ability to set channel moderation settings via the Graph API. We have an automated process to set up channels for incident resolution but users have to manually set the moderation settings which is inconvenient and cumbersome and error prone. Would be great to be able to turn this on and add moderators via the API

We should support more APIs as: multi download for folder and file...

categories have been added to the web to-do view, could we get them on the Graph API? Anyone creating Tasks in Outlook has probably set up a number of Categories (I know I have, and it is common 'getThingsDone' advice if using MS Tasks).

It seems open and schema extensions are not supported for File resources. It would be very useful to have that, especially as it was something kind of already available in preview in One Drive REST API with custom facets (https://docs.microsoft.com/en-us/onedrive/developer/rest-api/concepts/custom-metadata-facets?view=odsp-graph-online).
Having extensions on file would allow us to store custom metada on a file in the graph.

Would love to be able to edit the status (ie Gone for lunch - back at 2pm) via api.
Seems to exist via presence.teams.microsoft.com/v1/me/publishnote but at the very best this is currently an undocumented API
Business case - call center or helpdesk updating the status with the ticket they are currently working on, updating the status when back from lunch etc.

I have a use case where it would be nice to be able to Update or Delete Channel Messages of a Team via Graph API.

As per the API available, We can't link more than 1 linked resource for a task. When we try to create the second linked resource on that same task, it throws an error :

    "code": "invalidRequest",

    "message": "Linked Resource already exists.",

Request you to enable this feature as linked resource value response is available in array.

Users who posted message in Teams Channel can edit the messages later but through the graph api there is no options to update messages or delete messages.
POST /teams/{id}/channels/{id}/messages/{id}/replies seems like we can reply to the message but not update the previous message sent. Here I am talking about the same user's credentials. In Teams, a user can edit but not using graph api

It would be nice to have the ability to manage (CRUD) the authentication methods phone number with the application permission type. Currently the only option is to utilize the Delegated (work or school account) to be able to do these type of changes. We have a case where we would like to pre-load the MFA phone numbers for the users as well as in our testing environment to be able to populate test users including their MFA phone numbers. Being able to do this via a automated process/script would be hugely beneficial.

It seems Service Principals that manage an Application's AppRole currently require AppRoleAssignment.ReadWrite.All Graph role, which would grant it write permissions on all applications. This would make this Service Principal an attack vector and essentially make it impossible for a security-conscious admin to grant this role.
Graph could check that the Service Principal making an attempt to create an AppRole assignment is an Owner of the Application (like it does when a User is requesting this operation) and avoid requiring the highly-privileged AppRoleAssignment.ReadWrite.All.

Filter categories/any(a:a+ne+'Blue+Category') doesn't work with Calendarview

I would like to be able to pull mailbox configuration info for all mailboxes in my tenant. basically anything you can pull from Get-Mailbox powershell. I am specifically looking for settings like retention policy and litigation hold.

This is quite important for us to determine whether it's appropriate to read an email or not with our tool (currently everything is returned with no indication).

I'm sure there are many other use cases that require sensitive emails to be identifiable.

As, their is already ability for creating configuration tabs is available.
But we need to add static tabs also from the graph API for specific user. like suppose we have multiple content to show but we need to show some specific content on the basis of the user role. So here we need the ability to create static tabs also from 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.

We have APIs for fetching the permissions of individual drive items. However there is no API to fetch the sharing settings associated with a Sharepoint site and its pages - i.e. the users and groups allowed to access the site.
