Creation of bookings appointment leads to "UnknownError"

markusschnepf — Fri, 24 Apr 2026 19:30:00 GMT

Hi All,

I struggle to create an appointment via graph api.
I set up an app registration, added user, role, permissions and gave admin consent. i can successfully use GET requests to
- create a bearer token
and use this token to
- get company info
- get existing appointments
- get the services of your shared booking calender etc.

but when I try to create a new appointment, i always get responses like this

{
    "error": {
        "code": "UnknownError",
        "message": "",
        "innerError": {
            "date": "2026-04-24T19:18:44",
            "request-id": "178521f3-3e06-4790-a399-bdeda1c3eea7",
            "client-request-id": "178521f3-3e06-4790-a399-bdeda1c3eea7"
        }
    }
}

this is an example POST request (i removed all personal data) I want to send to:
https://graph.microsoft.com/v1.0/solutions/bookingBusinesses//appointments

important:
- the two customer questions I answered are mandatory, so i needed to fill add them to the request.
- also, I made the "additionalNote" mandatory in my service configuration.
- i added my staff ID to make sure, the problem is not about nobody being available.
for "start" and "end" i chose an appointment slot in which i am available, checked through our booking page.

unfortunately, this page does not really help. Erstellen von bookingAppointment - Microsoft Graph v1.0 | Microsoft Learn

Microsoft Graph - copilot/search how to get nextLink

Andrew Morgan — Wed, 08 Apr 2026 13:30:00 GMT

Hi, I'm having issues getting all the result back from from the search. I'm using "Graph Explorer" to try out /beta/copilot/search, using the request:

{ "query": "test", "pageSize": 10, "dataSources": { "oneDrive": { "resourceMetadataNames": [ "title", "author" ] } } }

I'm getting the response:

{ "searchHits": [ { "webUrl": "https://xxx.sharepoint.com/sites/xxxx/Documents/AM%20Test.docx", "resourceType": "listItem", "preview": "This is a Template Document This field, AM <c0>Test</c0>,comes from a workflow", "resourceMetadata": { "title": "AM Test", "author": "Andrew Morgan" } }, { "webUrl": "https://xxx.sharepoint.com/sites/xxxx/Documents/Test%20project.docx", "resourceType": "listItem", "preview": "This is a Template Document. This field, Test project,comes from a workflow", "resourceMetadata": { "title": "Test project", "author": "Andrew Morgan" } }, { "webUrl": "https://xxx.sharepoint.com/sites/xxxx/Documents/Presentation%20File.pptx", "resourceType": "listItem", "preview": "This is a test", "resourceMetadata": { "title": "Presentation File.pptx", "author": "Andrew Morgan" } }, { "webUrl": "https://xxx.sharepoint.com/sites/xxxx/Documents/Test%20project.xlsx", "resourceType": "listItem", "preview": "Input Key notes", "resourceMetadata": { "title": "Test project", "author": "Andrew Morgan" } }, { "webUrl": "https://xxx.sharepoint.com/sites/xxxx/Documents/Test%202.docx", "resourceType": "listItem", "preview": "Hello Everyone,\r\nWelcome to …......\r\n", "resourceMetadata": { "title": "Test 2", "author": "Andrew Morgan" } } ], "totalCount": 1668 }

What I dont understand is the totalcount is 1668. Buit it doesnt seem to make any difference what I set pageSize to in the request I only ever get back 5 results and also I was expecting "@odata.nextLink" to get the next page of results.

Can anyone shed any light on what i'm doing wrong or is it that i'm not understanding the document here:

https://learn.microsoft.com/en-us/microsoft-365/copilot/extensibility/api/ai-services/search/copilotroot-search

Microsoft Graph: Private channel SharePoint site URL naming appears to have changed

TheKevin — Fri, 03 Apr 2026 04:06:58 GMT

📄 Question

We are creating private channels using the Microsoft Graph API:

POST https://graph.microsoft.com/v1.0/teams/{team-id}/channels

With the following payload:

{ "@odata.type": "#microsoft.graph.channel", "displayName": "Project-Channel-001", "description": "Sample private channel for testing", "membershipType": "private", "members": [ { "@odata.type": "#microsoft.graph.aadUserConversationMember", "******@odata.bind": "https://graph.microsoft.com/v1.0/users/{user-id}", "roles": ["owner"] } ] }

🔍 Observed Behavior

When the private channel is created, the associated SharePoint site is provisioned automatically (as expected).

However, the URL format appears to have changed.

Previously observed behavior:

https://{tenant}.sharepoint.com/sites/ProjectTeamURL-Project-Channel-001

Current behavior:

https://{tenant}.sharepoint.com/sites/ProjectTeamName-Project-Channel-001

❗ Impact

This change introduces several issues:

Breaks deterministic URL generation logic
Produces longer and less predictable URLs
Introduces dependency on display name, which is mutable and may contain unexpected characters
Impacts existing automation and integrations relying on the previous pattern

❓ Questions

Has there been a recent change in how SharePoint site URLs are generated for private channels?
Is this behavior intentional and documented, or a regression?
Is there any way (via Graph or otherwise) to:
- Control the generated SharePoint site URL, or
- Retrieve the final site URL deterministically without relying on pattern assumptions?
Is the previous {ParentTeamUrl}-{ChannelName} format still expected in some scenarios, or has it been deprecated?

🧪 Additional Notes

This behavior is observed when creating channels via Microsoft Graph (v1.0)
The issue is reproducible across multiple test scenarios

🙏 Any clarification from Microsoft or others encountering this would be appreciated.

Microsoft Graph callRecords Webhook Not Triggering for Bot Initiated Calls

siddharthaveer — Mon, 30 Mar 2026 15:15:58 GMT

Hii,

I am working with the Microsoft Graph API and have set up a subscription on `/communications/callRecords` to receive webhook notifications whenever a new call record is created in our tenant.

Our Setup:

- Subscription resource: `/communications/callRecords`

- Change type: `created`

- Permission: `CallRecords.Read.All` (Application type, admin consent granted)

- Token: Generated using `client_credentials` (app-only token, NOT delegated)

What is Working:

- Webhook fires correctly for calls made from the Teams interface (user-to-user calls)

- Bot callback URL receives call state events (call establishing, established, terminated)

- callRecords ARE generated and visible via `GET /communications/callRecords` for bot calls too

The Problem:

- Webhook does NOT fire for calls initiated programmatically via `POST /communications/calls` (bot/application identity calls)

- Even though the callRecord exists and is visible in Graph API, no webhook notification is sent

Our Bot Call Payload:

```json

{

"@odata.type": "#microsoft.graph.call",

"callbackUri": "https://our-server.com/webhook",

"source": {

"identity": {

"application": {

"id": "our-app-id",

"displayName": "My Calling App"

}

"targets": [

{

"identity": {

"user": {

"id": "target-user-id",

"displayName": "User"

}

"requestedModalities": ["audio"],

"mediaConfig": {

"@odata.type": "#microsoft.graph.serviceHostedMediaConfig"

}

```

Our Questions:

1. Is this a known limitation — that `callRecords` webhooks do not fire for application/bot-initiated calls?

2. If the callRecord IS generated and visible via GET, why is the webhook notification system not triggering?

3. Is there any configuration, permission, or approach that can make the webhook fire for bot calls the same way it does for Teams interface calls?

4. Is `callChainId` the only reliable way to fetch callRecords for programmatically initiated calls?

We have already verified:

- Subscription is active and not expired

- Correct Application permission with admin consent

- App-only token used for subscription creation

- Webhook endpoint responds with 202 within 3 seconds

- callRecord is visible via GET after waiting 150 minutes

Waiting 150 minutes and polling manually works, but we want real-time webhook notifications just like we get for Teams interface calls.

Any official clarification or guidance from Microsoft engineers would be highly appreciated.

Thank you!

How long are kept onlineMeetings data (main teams data, attendanceReports)

Thanks for you support

Getting available time slots in Booking API

JesperNG — Wed, 25 Mar 2026 08:52:26 GMT

I am dumbfounded by the process of getting available/bookable time slots for a service in the Bookings API.

As I understand it, and as I have it working, I have to:

Fetch information about the service to get the SchedulingPolicy and its General and Custom availabilities.
Fetch information about the staff members connected to the service.
Fetch information from getStaffAvailability
Manually enumerate the time slots according to time slot interval, respecting the minimum lead time and maximum advance time.
Manually verify for each time slot whether any staff is available given the availability information.

(I could fetch the calendarView information but that only shows booked appointments, and so if a staff member is busy or out of office with another calendar event, that is not taken into account and the customer risks booking a time slot that was never possible to begin with.)

All this while managing time zone conversions at every step.

Is there really not one endpoint that just returns which time slots are available for booking right now for a given service within a given date/time range?

Unable to retrieve all attachments from forwarded Outlook emails using Graph API

akshaybabar — Sun, 15 Mar 2026 12:45:31 GMT

We have integrated Outlook with our system using Microsoft Graph API and subscribed to message events. Whenever we receive an event, we process the email message at our end.

Currently, we are facing an issue related to attachments in forwarded email conversations.

Scenario

An email conversation contains multiple replies.
Some of these replies contain attachments.
When a user forwards the entire email thread, Outlook generates a forwarded email that includes the conversation history in the email body.

Problem

When we receive the forwarded email event and fetch the message details using the Microsoft Graph API, we observe the following:

The forwarded email only contains the latest reply's attachment.
Attachments from earlier replies in the thread are not included in the forwarded message attachments.
In some cases:
- The first reply contains an attachment.
- Subsequent replies do not contain attachments.
- When the user forwards the email, the forwarded message JSON shows: hasAttachments: false

But, the forwarded email body still contains the previous conversation that had attachments.

Our Questions

Is there a way to retrieve all attachments from the entire email thread when a conversation is forwarded?

Can we retrieve these attachments using the current user's access token via Microsoft Graph API?

If there is a way, please also let us know how we can identify forwarded emails using the Microsoft Graph API, so that we can apply this solution only for forwarded emails.

Our Requirement

We need a reliable solution that works in production to ensure that all attachments from the email conversation are retrieved, even when the email thread is forwarded.

This issue is currently impacting our production system, so we would greatly appreciate any guidance on the correct approach.

Thank you in advance for your support.

Mails with attachments sent via the Graph API are stuck in drafts folder and not being sent

abhaykrishnakasavaraju — Thu, 05 Mar 2026 04:45:22 GMT

Mails being sent via Graph API using the createUploadSession way is keeping the mails in the Drafts folder and not being sent. This was working till mid January. Is there any graph update/ api deprecation that happened recently that is causing the issue?

Is principalId Always a GUID in Microsoft Graph ??

Agathiyan — Fri, 13 Feb 2026 08:32:21 GMT

{

"error": {

"code": "Request_BadRequest",

"message": "Invalid GUID:HR",

"innerError": {

"date": "2026-02-13T06:44:24",

"request-id": "87678d90-1d94-4131-a705-4356ad3568a4",

"client-request-id": "63569c7b-1dea-42d4-8d72-aa3668c78418"

}

We’re encountering an issue with the Microsoft Graph API response for directoryRole

Recently, one of our Graph API calls started returning a response where the principalId value appears to be a custom string instead of the expected GUID. In our code, we loop through each id from the delta response, assuming it will always be a valid GUID. However, we are now getting errors because one of the returned principalId values does not match the expected format.

Our questions:

Is it possible for Microsoft Graph API to return a custom string instead of a GUID for principalId?
Has anyone experienced similar behavior with delta queries for directoryRole or any other object?
Are there any known scenarios where the principalId format differs from the standard GUID?

Any insights would be appreciated.

Microsoft Graph API returns 502 Bad Gateway (UnknownError) when calling List members of a chat

Deleted security groups return "securityEnabled": false, appear as ‘unrecognized’ in Entra admin

soniabouna — Wed, 28 Jan 2026 21:49:12 GMT

When retrieving the list of soft-deleted groups with Graph, both M365 groups and security groups are returned.

However, the securityEnabled flag is returned as false for security groups. Is this a bug?

This likely leads to displaying them in the Entra admin center as 'Unrecognized' type.

Slow UI update for deleted events

devdevdev — Fri, 23 Jan 2026 09:47:14 GMT

I've built an integration that continuously syncs events between an external scheduling system and Exchange Online using Microsoft Graph.

I'm observing a recurring issue when deleting calendar events via Graph:

A DELETE request to Graph returns success (204 No Content).
A subsequent GET /events/{id} returns 404, confirming the event is deleted server-side.
However, the event continues to appear in the Outlook UI (both Outlook Web and desktop) for an extended period (sometimes hours), even after page reloads or app restarts.

The odd behaviour

The event is still displayed in the user interface for up to several hours
The event persist through page reloads
If the user clicks the event it opens briefly and immediately closes, the event disappears from the UI afterward.

Additional details

Delete endpoint:
```
/users/{id}/events/{id}
```
Graph response:
```
204 No Content
```
Verified deletion via GET → 404
Reproduces in both Outlook Web and Outlook desktop

Questions

Is this a known Outlook client caching or calendar view indexing issue?
Is there a way to force client reconciliation after deletes?
Are there Graph or Exchange constraints around rapid create/update/delete cycles that could cause this UI inconsistency?

How to Retrieve Windows Edition (SKU) from managedDevices API

KienQS — Tue, 23 Dec 2025 07:33:16 GMT

Hi everyone,

I am working with the Microsoft Graph API endpoint
/v1.0/deviceManagement/managedDevices
to iterate through all devices in a tenant and collect operating system related information.

For Windows devices, the operatingSystem field only returns "Windows". However, Windows has multiple editions such as Enterprise, Education, and Pro.

For my use case, I need the specific Windows edition. Is it possible to retrieve this information using only the v1.0 endpoint, or is the beta endpoint
/beta/deviceManagement/managedDevices/{managedDeviceId}
required to get the SKU family?

Thanks in advance for your help.

Is there possibly no official documentation for Windows 11 search?

SJB_NC — Sat, 20 Dec 2025 17:02:22 GMT

I have looked far and wide to find a definitive, official technical reference for the Windows 11 search service... especially for the various search parameters and the syntax they require from a savvy user to conduct a well specified, precision search for something. Is it possible that Microsoft has not produced a formal specification of Windows' search feature?

Would someone from Microsoft please, please, please provide a link to such a document? Is it possible to buy it? Does it exist anywhere? Am I deluded to think that that is something that the provider of the world's most used desktop OS would have had to create, as a matter of course?

I'm talking here about conducting searches, within the file system of a Windows 11 (Pro) machine, that one initiates from the "Search Home" box at the top right of every File Explorer window that gets opened by the user.

Any thoughts from someone actually involved in creating the search tool?

Imploringly yours,

SJB

Alias for Refinable Managed Property Not Working in Search Queries

Sean17 — Mon, 15 Dec 2025 08:36:30 GMT

Hi,

The alias for the refinable managed property has worked as expected in sortProperties for the past year, but it has recently stopped working and now returns an error. Using the original managed property name (RefinableDateSingle01) continues to work as expected.

The error is shown below, together with the trace ID. Unfortunately, we are unable to switch to using RefinableDateSingle01 in sortProperties as it does not meet our business requirements.

We are currently facing challenges due to the large number of SharePoint sites, many of which we do not have permission to access. As a result, we can only confirm that the refinable managed property RefinableDateSingle01 and its associated alias are configured correctly on the SharePoint sites where we have full access.

What is the root cause of this issue, and how can it be resolved?

https://graph.microsoft.com/v1.0/search/query

Microsoft accounts

Blaz3ym0use — Fri, 28 Nov 2025 12:24:29 GMT

Hi all.

I have a problem with my daughters Microsoft accounts which I'm hoping you can help with.

She set up an account for her X Box on my email address (without asking me first) which is preventing me from setting up my own account for Windows.

Since then she has also set up a Hotmail account with her own email address. I understand we can set up an alias on the X Box account using her email but will this conflict with the Hotmail account. The problem is she doesn't want to change her gamer tag which was set up on my email address.

Any help / advice will be gratefully received.

Many thanks in advance
