Get list of conversations a bot has participated in from BotConnectorAPI
Hi! My team is building a Microsoft Teams bot, and we are trying to get a list of conversations (channels) that the bot has participated in using the BotConnectorAPI. We are trying to use this endpoint: https://learn.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-connector-api-reference?view=azure-bot-service-4.0#get-conversations, however we keep getting 405 errors "The requested resource does not support http method 'GET'". Are we doing something wrong, or is there any other endpoint we can use?
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.Cannot log in to Teams meeting

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 · CommunityRunning Teams PowerShell Cmdlets in Azure Automation
This article describes the prerequisites and how to run cmdlets from the Teams PowerShell module in Azure Automation runbooks. We also consider when you’d want to consider using Teams PowerShell cmdlets instead of Graph API requests or cmdlets from the Microsoft Graph PowerShell SDK. The bottom line is that it’s possible, but maybe not a frequently-used option. https://office365itpros.com/2025/09/12/teams-powershell-azure-automation/
Test call option not showing up in Teams?
Hi I've downloaded a personal version of Teams and need to test it. However, the 'Test call' option is not available? I've tried 2 methods: 1) typing 'Test call' in the search bar and pressing enter - nothing happens when I do this! 2) going to Settings then Devices then checking for the 'Test call' option - but it's not there! I've attached what I can see when I got to Devices and what I should be able to see (from a video I watched online) I'm using Version 1.4.00.22472 (64-bit). Can anyone please advise?
How to embed large text blocks in a chat message
I am trying to include a large-ish code snippet in a Teams message. I understand that the message itself can only be so many characters, but is there a way to create an ad-hoc object to place a larger text chunk in, rather than save my content to a file and attach the file?
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

how to achieve private stage view for custom team app in meeting
I’m working on a custom Microsoft Teams app that will be added to a meeting. My goal is to have the app load in a private stage view as a popout when clicked, so that only the user who clicked it can see the content, without broadcasting it to all meeting attendees. I've created a custom Teams app for meetings, but I'm facing an issue with the viewing behavior. Currently, when a user clicks the app during a meeting, the content first loads in the side panel. The user then has to click a "Share" button to push the content to the main meeting stage, which makes it visible to all attendees. However, what I want is for the app to immediately open in a private stage view (as a popout) when clicked, without showing anything in the side panel and without requiring the user to manually share it. The content should only be visible to the individual user, not broadcast to the entire meeting.Teams Support for Emojis in Chat and Channels Section Names
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/
