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.Teams App Error After 60 Seconds: "There was a problem reaching this app"
Problem My Teams tab app loads and works perfectly fine, but after exactly ~60 seconds, it shows this error screen: "There was a problem reaching this app" with a Retry button (Screenshot attached) Setup Teams Personal & Meeting tabs Node.js backend on Azure Azure AD authentication Multi-tenant app What I've Checked ✅ No errors in browser console ✅ No errors in server logs ✅ All API calls complete successfully ✅ Teams SDK initializes without errors ✅ Authentication tokens are valid ✅ App works fine locally - only happens in production The Strange Part The app functions normally during those 60 seconds. Everything loads, authentication works, API calls succeed. Then suddenly this error appears. The 60-second timing seems too consistent to be coincidental - suggests some kind of timeout. Question Has anyone seen this before? Is there a Teams SDK timeout or callback I'm missing? Should I be calling some kind of notifySuccess() or similar after initialization? Any suggestions on what could cause a delayed error like this would be appreciated!
Recording meeting doesn't work with animations
I recently discovered utilizing animations and presenting PowerPoint live mode is not capturing the animations. In other words, each slide is being recorded as if there is no animations applied. This is not good since we want to phase in the content from the slide. Update/clarification - turns out the recording of the meeting, if using any other format - Presenter Modes for example, does capture the animations on the slides. It is only when attempting to record the meeting while the Presenter has selected PowerPoint live is when the animations are not captured in the recorded file - participants within the meeting are able to see the animations as they occur - but recorded viewers will not. Just wanted to share the "work around". Thanks!
Removing someone from team and team meetings
Good morning I have set up a team with several internal and external contacts. I have created a reoccurring meeting for the team. If the team members change (a contact added or removed) will the meeting adjust accordingly? IE will those removed from the team be removed from the meeting and those added to the team - will they receive a meeting invitation? Thanks in advanceAllow muting a person only for me
Sometimes I am in a meeting where one of the persons in the meeting is actually near me in the world outside the screen. In this case the sound is a bit maddening since there is a small delay between the sound from the person and the sound through the teams interface. In these cases, I would like to mute the person only for me since I am sitting near and can hear the person fine without headphones. Right now I need to takeoff headphones when the person is talking and putting it back as the person finishes talking.MS Teams Mission Control Center
We provide meeting/webinar support for a major client using MS Teams. Highlighting participants via "Spotlight" in large meetings is quite cumbersome, especially during Q&A sessions, and it's relatively time-consuming and causes awkward pauses. Isn't there a way to improve this? Perhaps an external control page? Furthermore, it would be very helpful to be able to switch seamlessly to different cameras and videos without having to go through OBS or Vmix, or connect a hardware video mixer. Are there any solutions on the market that don't require multiple people to manage a meeting with high demands? If not, we will need to develop this ourselves 😉.Teams Private Channels Just Got Powerful: 1,000 Channels, 5,000 Members & Compliance Simplified
Microsoft Teams Private Channels just got a major upgrade — bigger limits, meeting scheduling, and a simpler compliance model aligned to Microsoft 365 group mailboxes. 🚀 Here’s the key takeaways for IT leaders and Teams admins: Scale up: up to 1,000 private channels per team and 5,000 members per private channel. Meetings supported in private channels. Compliance simplified: private channel messages now live in the team’s M365 group mailbox, aligning DLP, Retention, eDiscovery, and Legal Hold across channel types. Migration timeline: worldwide rollout started in Oct–Dec 2025, with a PowerShell cmdlet to track status: Get-TenantPrivateChannelMigrationStatus. Admin checklist Add your Teams’ M365 group mailbox to Purview DLP/eDiscovery/Retention scopes. Verify Teams channel messages retention applies across standard/shared/private. During migration, ensure searches/holds include both group and user mailboxes. Monitor progress with the cmdlet above. #MicrosoftTeams #PrivateChannels #Microsoft365 #Compliance #Purview #DLP #eDiscovery #TeamsAdmin #Collaboration
New Teams - Video freezing
I have no issues using the "old" version of teams. The problem only occurs in the "new" version. In a meeting all incoming video turns black (including shared screens). my image "floats" in the middle of the screen and is also frozen. The "mini" window when I minimize the application during a meeting show live/unfrozen incoming video of the speaker. Version Info: You have Microsoft Teams version 23231.413.2355.7555. You've got the latest version. It was last updated on 9/12/2023. The client version is 49/23082000931.
external company telling me i need to allow my users to enter their meetings
does this make sense to anyone? I have an outside company telling me that they are creating Teams meetings for my company and potential candidates. She indicates that my company is the only company that is not allowed to start the meetings she creates. This does not happen to any of her other customers. She's asked me that I get this fixed on my end. What am i missing here? Is there some sort of setting in my tenant that says do not allow my users to start an external teams meeting?
