Add Teams Chat Member API call inexplicably Failing
I have tried every possible permutation of this API call that I can imagine. Nothing works. I already started a thread on this, but now it appears to be glitched and I can no longer reply to message sin that thread for some reason. What can I do to contact Microsoft Support and speak directly to their API team? The responses I have gotten all appear to be AI generated and NONE ARE CORRECT. I really need help, from a human, that actually might understand what's going on here. Please help. "#microsoft.graph.aadUserConversationMember' for 'odata.type' is not valid for this operation." <- I am receiving this error despite the fact that we already have several users in this channel with that same type. This API call is intended to invite a user to an existing group chat. This should really be a very simple thing. 1. ALL users in the group chat already have type = '#microsoft.graph.aadUserConversationMember' so the error message doesn't even make sense. 2. This IS a Group chat. NOT a channel. NOT a one on one chat. 3. The Inviter has permission to invite users to this groupchat through the frontend. (and in fact can do so using the frontend.) Why is this API call failing? I have tried scrubbing the API call of special characters, I have tried using the beta endpoint, I have tried several different formats for the input. ERROR: {"error":{"code":"BadRequest","message":"The provided '#microsoft.graph.aadUserConversationMember' for 'odata.type' is not valid for this operation.","innerError":{"date":"2026-02-10T19:11:28","request-id":"XXXXX","client-request-id":"XXXXXX"}}} POST URL: https://graph.microsoft.com/v1.0/chats/IDHERE/members BODY: { "chatType": "group", "\u0040odata.type": "#microsoft.graph.aadUserConversationMember", "user\u0040odata.bind": "https://graph.microsoft.com/v1.0/users/IDHERE", "roles": [] }
Status during a Teams call : "in a call" only once others have joined!
Hi, I work remotely so most of my job is through Teams calls with laypeople (i.e. not necessarily Teams savvy). I like to start the calls a few minutes before to prepare my shared whiteboard, etc., make sure sound is OK... However, the status, even when I'm alone, is automatically "in a call" and so I don't have notifications anymore, which is generally OK, except that if my client tries to call me on the phone (which is on Teams), they go directly to voicemail. It is annoying to manually switch it. I think that when we are ALONE in the call, waiting for others to join, we should appear as AVAILABLE so that all notifications, etc. are still enabled until we are not alone in the meeting... and then, yes, all the do not disturb aspects must kick in! Thanks!
Meeting Bot issue: Did not receive valid response for JoinCall request from call modality controller
I'm trying to join a Teams Meeting with a bot. I used this https://microsoftgraph.github.io/microsoft-graph-comms-samples/docs/articles/index.html#making-an-outbound-call-to-join-an-existing-microsoft-teams-meeting sample. When the bot attempts to join I get the popup to admit or deny it in the meeting, but as soon as I click admit, it drops. In the logs I see this message: Call status updated to Terminated - Did not receive valid response for JoinCall request from call modality controller.. DiagCode: 580#5426.@ I am using the latest (1.2.0.10563 at time of writing) version of Microsoft.Graph.Communications libraries and the problem only started after I updated from 1.2.0.3742 that I was using previously. I could not find any info on what the call modality controller is, or how to check what it is responding if anything. Any ideas on how to troublshoot this are welcome.
Call Event when one user calls another user so that Bot can be added to call
We have developed our Bot application and can record all media(audio, video) locally when a user directly calls the Bot User. However, we do not get a call event when one user calls another user - so that we can add the Bot to record the call. Both users have the global default compliance policy which allows recording. We have provided the necessary permissions to the Bot. What are we missing ? Thanks
Affordable Conference Room Setups for Small Businesses Using Microsoft Teams Resource Accounts
Our small business (around 40 users) recently migrated from Google to Microsoft 365, and we’re facing several challenges in optimizing our meeting rooms for Teams without incurring large costs. Here’s our current setup and the main issues we are encountering—hoping for advice or creative solutions from the community. Current Setup All computers are domain-joined. We created resource accounts for each of our three meeting rooms; these appear correctly as Rooms in Outlook and Teams booking menus. Each meeting room contains a standard desktop PC (not MTR-certified) running Windows, logged into Teams as the room’s resource account. Employees use the meeting room computer to join calls and manage the meeting calendar. Current Issues Wireless Presenting (Casting): Teams’ wireless casting feature appears to require MTR-certified hardware, which is financially out of reach for a business our size. Unplugging and plugging HDMI cables is cumbersome and error-prone, especially since not everyone uses a laptop, and reconnecting the room PC is often forgotten. Agenda & Calendar Privacy: When meetings are booked, the full Teams agenda and chat history remain accessible on the meeting room machine. That means anyone in the room can view past meetings/agendas, which isn’t ideal from a privacy perspective. Screen Sharing and File Security: To present from the meeting room PC, any files must be accessible by the resource account, creating additional security concerns and sharing/permission headaches. What We’re Looking For Affordable wireless presenting options for meeting rooms—ideally something that integrates smoothly with Microsoft Teams, but without requiring full MTR hardware. Best practices to lock down or reset the meeting room PC so meeting agendas, chats, and files are not visible after a session. Secure ways to allow guests to present (screen share, share files, etc.) without exposing company data or making users jump through complicated permission processes. If anyone has experience setting up small, cost-effective Teams Rooms, especially with regular PCs rather than dedicated MTR devices, advice would be greatly appreciated! Specific steps, hardware/software recommendations, or management tips would all be helpful. Thanks in advance for any guidance!
Issue with Deep Link to Meeting Side Panel in Microsoft Teams
Dear Team, I hope this message finds you well. We are currently experiencing an issue with the deep link to the meeting side panel in Microsoft Teams. Despite following the documentation provided at the link below, the functionality is not working as expected: https://learn.microsoft.com/en-gb/microsoftteams/platform/concepts/build-and-test/deep-link-workflow?tabs=teamsjs-v2#deep-link-to-meeting-side-panel When attempting to use the deep link, we encounter the following issue: Instead of opening our custom application in the side panel, the meeting window opens with the chat displayed on the right-hand side. And in the background, I am getting the below error. We would appreciate your assistance in resolving this matter, as the deep link is a critical component for our application integration within Microsoft Teams. Thank you for your prompt attention to this issue. Best regards, Sukesh PKSide-panel Teams meeting app becomes unusable but stays open/visible when user joins a breakout room
I am working with a side-panel Teams meeting app. A customer noticed behavior that I have been able to replicate but have not found an explanation for, or a way to prevent. Issue summary When a user has a side panel app open, and the user is pushed into a Teams meeting breakout room, the side panel app remains open/visible but the app content disappears (making the app unusable). Replicating this behavior 1. User has app open in Teams meeting side panel. In the below screenshot, note that the app is listed in the interface (red circle), and open in the side panel. 2. User is pushed into a breakout room. The user does not interact with the interface and is automatically pushed into a breakout room. 3. Upon joining the breakout room, the app appears to remain open in the side panel, but the content disappears. In the below screenshot, note that: The side panel app content is now empty/blank. The app icon disappears from the Teams meeting interface (red circle). This is expected, but just want to note that the app is not attached to the breakout room at all. Thoughts My understanding is that apps don't carry over from the main Teams meeting into breakout rooms (though apps can still be added inside of breakout rooms), so the curiosity here is why the side panel app remains open when moving from the main room to a breakout room. And one more interesting note — using the three dots and "Reload" on a side panel app gets the app to reload and work again inside the breakout room, despite the app not being listed as an interface tab within the breakout room. I don't necessarily need the app to remain usable as a user joins a breakout room, but I am wondering what's going on here with the app remaining open/visible.
Since Aug 22nd we can't save any Side Panel tabs
Hello! Yesterday (Aug 22nd 2025) we got an update in our Teams Links that we normally share to start meetings. They were modified from this format: https://teams.microsoft.com/l/meetup-join/19%3ameeting_XXXXXXXXXXXXXXX%40thread.v2/0?context=%7b%22Tid%22%3a%22xxxxxxxxxxxx%22%2c%22Oid%22%3a%22xxxxxxxxxxxxxx%22%7d to https://teams.microsoft.com/meet/00000000000?p=XXXXXXXXX Sensitive values and ids have been redacted above and inside all the snippets in this post. This looks like a planned rollout, as specified here: https://mc.merill.net/message/MC772556 After this change, none of our apps are able to save a side panel into any of the meetings with the new link format. We had a couple of older, still available meetings whose link had the previous format, and we are able to save the side panel there, but no matter what we tried, nothing allowed us to solve this situation on our end. My final resort is this post in hopes of a solution to what we see. Each save operation yields a 500 on this call https://teams.microsoft.com/api/chatsvc/amer/v1/threads/19%3Ameeting_XXXXXXXXXXXXXXXXXX%40thread.v2/properties?name=tab%3A%3Axxxxxxxxxxxxxxxx { "errorCode": 500, "message": "{\"subCode\":\"TabOperationFailed\",\"details\":\"Initiator 8:orgid:xxxxxxxxxxxxxx failed perform tab operation\",\"errorCode\":1500,\"errorSubCode\":null}", "standardizedError": { "errorCode": 1500, "errorSubCode": 1, "errorDescription": "TabOperationFailed-Initiator 8:orgid:xxxxxxxxxxxxxx failed perform tab operation" } } I ended up trying to manually install it with graph api calls, which didn't work either and gave me a 502 curl -s -X POST "https://graph.microsoft.com/v1.0/chats/$CHAT_ID/tabs" \ -H "Authorization: Bearer $ACCESS_TOKEN" -H "Content-Type: application/json" \ -d '{ "displayName": "DisplayName", "email address removed for privacy reasons": "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/'"$TEAMS_APP_ID"'", "configuration": { "entityId": "entity-random", "contentUrl": "https://<domain>/?theme={theme}&locale={locale}", "websiteUrl": "https://<domain>/" } }' | jq . { "error": { "code": "BadGateway", "message": "Failed to execute backend request.", "innerError": { "date": "2025-08-22T03:36:08", "request-id": "b4bbade7-1ea2-46df-a1d9-92cdda9e360b", "client-request-id": "b4bbade7-1ea2-46df-a1d9-92cdda9e360b" } } } Then, thinking there was something wrong with my app, I used a MS app, same result curl -s -X POST "https://graph.microsoft.com/v1.0/chats/$CHAT_ID/tabs" \ -H "Authorization: Bearer $ACCESS_TOKEN" \ -H "Content-Type: application/json" \ -d '{ "displayName": "Website - test", "email address removed for privacy reasons": "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/com.microsoft.teamspace.tab.web", "configuration": { "entityId": null, "contentUrl": "https://www.microsoft.com", "websiteUrl": "https://www.microsoft.com" } }' | jq . { "error": { "code": "BadGateway", "message": "Failed to execute backend request.", "innerError": { "date": "2025-08-22T04:02:36", "request-id": "ece5590e-f23f-4780-a4a6-20c1b2f0d0f3", "client-request-id": "ece5590e-f23f-4780-a4a6-20c1b2f0d0f3" } } } I then tested it against chats that do not belong to a meeting.

It's affecting our tenants in all environments, since our primary business flow relies on this panel. All the snippets contain real dates and request-ids, here's hoping it helps somehow. Help, and thanks in advance. ~A. del YerroMicrosoft Graph - List apps in chat - 404 UnknownError
In Microsoft Graph, I would like to list all Teams apps associated to an onlineMeeting (to its chat actually). According to List apps in chat - Microsoft Graph v1.0 | Microsoft Learn, this is supported with the following request : GET /chats/{chat-id}/installedApps There is a note saying that if the chat is associated with an onlineMeeting instance, then, effectively, the teamsApps installed in the meeting will be listed. That should work. However, I'm getting a 404 with UnknownError as the error.code on my end. The right permission (TeamsAppInstallation.ReadWriteForChat) is granted (Chat.ReadWrite is granted as well). Testing from Graph Explorer from now. Please note that the following is working to get chat messages with the same chat-id : GET /chats/{chat-id}/messages or the following to get chat members : GET /chats/{chat-id}/members I've tried the endpoint POST /chats/{chat-id}/installedApps to add an app to the chat as well but I'm getting the same kind of 404 (documented on Add app to chat - Microsoft Graph v1.0 | Microsoft Learn). Any advice? Thanks
