Teams channel messages delta API returns HTTP 400 BadRequest
Hello, We are encountering an unexpected error when calling the Microsoft Graph API endpoint: /teams/{team-id}/channels/{channel-id}/messages/delta This happens consistently for a specific Teams channel, which prevent us from retrieving incremental message updates using the delta query. Request URL: https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/messages/delta?$deltatoken=<redacted-deltatoken> Error Response: HTTP 400 { "error": { "code": "BadRequest", "innerError": { "client-request-id": "<redacted>", "date": "2025-10-07T06:32:56", "request-id": "<redacted>" }, "message": "UnknownError" } } Steps already tried (unsuccessful): Start a fresh delta query without the $deltatoken to obtain a new valid token Use the beta endpoint: https://graph.microsoft.com/beta/teams/{team-id}/channels/{channel-id}/message/delta Additional observation: If we add a filter condition such as ?$filter=lastModifiedDateTime gt <some-timestamp> to skip messages before a certain time, the query works normally. This suggests that there may be one or more problematic messages within a specific time range that cause the API to fail with BadRequest. Questions: Is this a known issue with the Teams channel messages delta API? Are there any recommended workarounds to avoid this error? Thank you.
Support RTL Languages on MacOS
As now, It seems Microsoft teams on MacOS does not support RTL languages when texts are being typed. This makes bad feeling when users want to read the text they've typed. The issue becomes worst when the text contains English phrase (when the message is sent) As far as I remember, Skype did support RTL languages when the texts are being typed.
The Teams Developer Portal needs administrative views
The Teams Developer portal needs some way for Teams service admins or Global admins to view everything that is being deployed to the catalog both in a published and unpublished state. Alternatively, develop some graph endpoints that could be turned into cmdlets in Microsoft Teams PowerShell module or the Graph PowerShell SDK module. As administrators we need the ability to help with keeping our tenant clean, so these kinds of views or endpoints would allow us to make sure that anything uploaded and not needed may be removed or reassigned if the underlying owner leaves and someone else needs to take over something they've been developing. I've submitted a feedback item to the portal - so please help by adding a vote to the entry to bring it up as an enhancement for the Teams Developer Portal services. The Teams Developer Portal needs administrative views or PowerShell/Graph capabilities to manage uploaded solutions and other artifacts · Community
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!How to Add a Timer to Microsoft Teams Meetings | Step-by-Step Guide

Teams users can use emojis to create or rename chat section names. By incorporating emojis into section names, users create “visual anchors” to help navigate through Teams chats and channels. Sprinkling emojis around section names doesn’t really make me navigate any smarter, but it’s a feature that Slack has, so Teams can’t be left behind in the pretty interface stakes. https://office365itpros.com/2025/10/08/teams-chat-section-names/Teams Bluetooth Audio Stack - Headphone vs Headset Failure
Been having a strange issue since the latest update on New Teams (1st Oct 2025 updated). This only happens with Bluetooth and with Headsets like PLT Voyager Legend and Yealink BH71 and on Windows 11. Mobile phone Teams works fine and to be clear, all other apps work fine with the Headsets. Its ONLY Teams doing this, and onluy since this update - worked perfectly for years before. When my device is connected Teams is separating the Speakers as Headphone and the Mic as Headset. This now means that when using the Mic, it won't play audio through the headphone (speaker) and vica versa when using the speaker (headphone) it won't allow the Mic (headset) to be used. This is a MASSIVE regression and extemely frustrating for any mobile user. I thought this was a PLT issue, so I bought a brand new Yealink BH71 and connected it via bluetooth and it did exactly the same thing. To be clear, this was working perfectly for months and years before this latest update.
Premium Planner major flaw: Transfer to other groups does not work

BUG: Teams "search"/"find" functionality totally broken with rich (formatted) text
Consider the following formatted/rich text comment: Test word1 word2 word3 Using "search"/"find" (either the global "Search", or the "Find in chat" function) will fail to match the comment when searching for either "test", "word1", "word2", or "word3". This is because buggy Teams just strips the formatting (instead of replacing the formatting with breaks), effectively glueing all words together in the index; searching for "testword1word2word3" (one word) DOES match the comment. 🤦🤦🤦
Client authentication EKU changes in public TLS certificate
Hi, Can someone clarify the upcoming change to remove the client authentication EKU and the conflicting information within MS docs for Teams Direct Routing certificates? As stated here from October 2025 there is an industry wide change to remove the client authentication EKU from issued TLS certificates: https://knowledge.digicert.com/alerts/sunsetting-client-authentication-eku-from-digicert-public-tls-certificates However, both server and client EKU's are required for mTLS and Microsoft states here that both server and client EKU's are required: https://learn.microsoft.com/en-us/microsoftteams/direct-routing-whats-new#sbc-certificates-eku-extensions-test Digicert are offering an X9 PKI that includes both server and client EKU's but it seems the signing CA is not trusted by Microsoft at this stage. What guidance are Microsoft offering with this upcoming change to ensure that customers are not affected when renewing their certificates?Library switching removed
I just realize that the library switch feature is not available anymore in Teams (reachable from the main channel) We are now forced to open in SharePoint to access this feature. This is a lost of productivity for users who want to access other libraries in the site... I can't understand why this was removed. Is there a technical reason?
Issue with Link Redirects & Metadata Previews in SharePoint / Microsoft 365
Hi everyone, I’m running into a weird issue with external group/invite links when they’re shared through SharePoint / Microsoft 365. Here’s what happens: I’ve got a page like this: justgroup.link/online-earning-whatsapp-group-links When someone clicks a link from that page, it should redirect them into WhatsApp or another app. But sometimes the redirect doesn’t work smoothly — it either stops halfway or doesn’t open the target app. Also, when the link is shared through SharePoint, the preview (title, description, image) often doesn’t load at all. I’m wondering if this is caused by: How Microsoft 365 / SharePoint handles redirects from non-static pages OG (Open Graph) tags or headers not being read correctly Some kind of security or link-rewriting filter that blocks redirects to external domains Has anyone else run into this? And does anyone know the best way to set up metadata / headers so previews show correctly, or make sure the redirect always works?Copilot Transcription Behavior Changing for Teams Meetings
Microsoft plans to deploy an update to change how transcription behaves for Teams meetings where Copilot is enabled. New meetings will not generate a transcript unless the meeting organizer explicitly enables transcription or the Microsoft 365 tenant deploys custom meeting policies that enable transcription with Copilot. The AI features work even without a transcript. But no transcript means no searchable artifact, and that’s what some want. https://office365itpros.com/2025/09/15/transcription-teams-meetings/Unable to Save Tab Configuration in Teams Meetings
Hello, Over the past few days, I have been unable to add any apps during a meeting in Microsoft Teams. I have tested this with multiple apps, and each time I receive the following message: “Unable to save {APPName} tab configuration.” I have attempted this both in the Teams desktop application and in the browser version, but the issue persists in both. When checking the browser’s developer tools (Network tab), I noticed that the related request consistently returns a 500 error code: https://teams.microsoft.com/api/chatsvc/emea/v1/threads/{XXX}/properties?name={XXX} { "errorCode": 500, "message": "{\"subCode\":\"TabOperationFailed\",\"details\":\"Initiator 8:orgid:{XXX} failed perform tab operation\",\"errorCode\":1500,\"errorSubCode\":null}", "standardizedError": { "errorCode": 1500, "errorSubCode": 1, "errorDescription": "TabOperationFailed-Initiator 8:orgid:{XXX} failed perform tab operation" } } Any assistance in resolving this would be greatly appreciated.
Remote Access in Pro Portal not working with Public Preview R3.6
When I try to use Remote Access via the Pro Portal, I can connect to the MTR but the image is flashing. I cant seem to have a stable session with the MTR. The screen will go to black for around 5 seconds, then it shows what is on the screen for less then 1 second. I tried it on 2 MTR devices that I have in our labo but the issue remains. When I revert the option for Public Preview back to off, I am able to connect and use Remote Access via the Pro Portal without any issue. We are using MTRoW and have the latest updates.
How does Teams create the edit history for an uploaded document
Hello, I would really appreciate some help in understanding how microsoft teams creates the edit history for new version of a document which is uploaded to it. Here is the scenario: I download an MS Word document from teams to my laptop and over the period of a few days, I edit that document. The word document did not have track changes switched on whilst editing and therefore does not contain any edit history. I then upload the edited document to Teams. Despite the word document having no edit history embedded in it, in the version history of the document in Teams it shows each of the edits I have made since I downloaded it with a date and timestamp of the date on which I uploaded it, rather than the date(s) on which I actually made each of the changes to the document. This suggests to me that the way in which Teams creates the edit history for the document is to run a compare of the newly uploaded document with the previous version stored on Teams and attribute all the changes to me on the date upon which I uploaded it. Is this correct? If not I would appreciate a description of how that document edit history is created by Teams. If there is an official Microsoft document which describes how this works then a link to that document would be great. Many Thanks for your help BigbigblueHow to Update Entra ID Apps to Run Teams Cmdlets
MC1134747 describes a new permissions requirement for Entra apps that run Teams PowerShell cmdlets. Despite what you might think after reading some of the overhyped and ill-informed online commentary about this topic, this is not a dramatic security change, and it's easy to update apps to meet the new requirement with PowerShell. First, find the apps that use Teams PowerShell (we show two ways), and then assign the two required permissions to the apps. All done with a few lines of Microsoft Graph PowerShell SDK code. https://office365itpros.com/2025/09/05/update-apps-teams-powershell/
