Teams Webinar Confirmation Emails Not Sending
Hello! I'm trying to setup a Webinar for my company and several people have registered for the webinar, but no one has received a confirmation email with the calendar invite/join now link. Has anyone else been dealing with this issue? I'm unsure how to fix at this time.SolvedhaleyjoAug 27, 2025Copper Contributor15KViews0likes32CommentsTeams Live Event : Audience gets "Can't load the live event. Try rejoining" message
I've tried searching for information about this error but haven't found anything (one Reddit post only). We've run Teams Live Events for many years. Several hundred attendees at a time, 8 to 12 presenters and producers. The past two weeks 5th May and 10th May we've had some attendees (likely less than 10 per event) that have joined then been shown the following message "Can't load the live event. Try rejoining" I thought it might be an issue due to the organiser's Teams version differeing from the Audience member's TEams version but that wasn't the case. V1.6.00.6754 on 5th May. We thought it might be due to poor internet connection but on both dates, one person in our head office had the problem, even though the other staff in the same physical location didn't have the problem. Given that the same issue occoured on 2 different dates AND impacted different staff (some the overlap) I believe the problem is a TEAMS Live Event bug. I'll log a Microsoft ticket but wanted to ask the community if any one else has seen this issue?Dorje-McKinnonAug 20, 2025Iron Contributor3.4KViews0likes3CommentsWhen guests are not permitted to join a Teams call
I organize Teams meetings with external guests, and I use an Azure Microsoft 365 group my org manages to grant permission to join the call. There are certain domains that get the above message. They are not given any option to log in as a guest, as they should. The message is ambigous in that it doesn't state which org policies are being enforced - the guest or the meeting organizer's. Is there anything on my org's side that we can do? Or, is it entirely on the guest's side that they have some our tenant blocked If it is on their side, I wish I could give them some instructions to troubleshoot. My org's IS has been unable to solve the issue.ux0042Aug 08, 2025Copper Contributor54Views1like1CommentTeams Webinar Can't edit internal presenter bio
Trying to set up a new webinar but I'm not able to edit the bio of an internal presenter. I'm organizer and presenter but I can't edit the bio because the save button is greyed out. I have already tried it with Teams for Windows, Teams for Mac and also in the browser. The same result everywhere, the button is greyed out. In contrast, I can edit and save the theming. Duplicating an older webinar (where the correct bio is already included) cannot be saved either. Error message "Something went wrong, and we need to try again." I think this is a "new" Teams related issue but I'm not sure. Any idea. ThomasSolvedThomas KrampeMay 19, 2025Brass Contributor1.4KViews2likes14CommentsTeams Live event RTMP server disconnecting
Hello, Tonight we have a webinar at my work. I found out that with a public live event in teams u can use a external RTMP encoder like OBS Studio. I used all the settings Microsoft has https://learn.microsoft.com/en-us/stream/live-encoder-configuration#:~:text=the%20live%20event.-,Recommended%20encoder%20settings,must%20be%20present%20in%20order%20to%20playback%20content%20in%20Microsoft%20Stream.,-Configuration%20tips I changed my MTU size and firewall to optimize the connection, but yesterday morning everything work without problems but in the evening it just doesn't wanna work anymore. I did a test to make sure the connection was stable and it was completely stable. I have read that these problems are serversided, is there a problem somewhere? I have the same issues with OBS at home when i try to stream to a teams live rtmp.

I’m reaching out to inquire about the confidentiality practices followed during Microsoft’s support for webinars, townhalls, and large-scale meetings under the Microsoft 365 Live Event Assistance Program (LEAP). As per the program details, Microsoft offers guidance and live assistance before and during events. In this context, I would like to confirm: What confidentiality and data protection measures are in place during this engagement? How is sensitive organizational content (such as internal discussions, executive communication, or client data shared during events) handled by Microsoft engineers or support staff? Are support personnel under NDAs or bound by Microsoft’s internal compliance framework when participating in rehearsal and live support sessions? We highly value privacy and information security and would appreciate written confirmation regarding the safeguards implemented during your assistance with such events. Looking forward to your response.AyushShuklaApr 30, 2025Copper Contributor43Views0likes0CommentsTownhall meetings unable to disable attendee response
Hi, Is there a way to disable the email notification response for when attendees accept/decline the townhall meeting? I know I can disable the email entirely but this option prevents me from adding a distribution list or attendees directly into the townhall meeting setup in teams. Is adding a link to the townhall meeting and putting it in a seperate outlook calendar meeting the only option to not get the response from the meetings? Why is this not disabled by default? Townhall meetings are meant for large numbers of attendees. Nobody wants 800+ notification emails in their inbox. Please let me know if there is another way to do this.IcebeamerApr 25, 2025Copper Contributor168Views2likes1CommentWebinar - Attendees Joined 3 Different Calls
Hello! I facilitate a monthly call and I've been instructed to schedule the call through my personal calendar as a TEAMS Webinar. The invitation is sent to 1500 colleagues. IT instructed me to send out three different Outlook invites due to the maximum limit of 500 recipients. I then take the webinar call details and I copy the call in details into the three separate outlook invites. This past week when colleagues started to join the call some called into the January meeting/started a chat, some called into the February meeting/started a chat and come called into the correct meeting. Those that dialed into the incorrect calls (January and February) were unable to join the correct March meeting. Even after I copied the event link in the Webinar invite they were unable to join. It asked them to register for the event, but then gave them an error. Even stranger, I set up the Outlook invite by business unit, the incorrect meeting chats for January and February each had colleagues from all three business units. Can you confirm, is the webinar the best application and is it true that I must set up the webinar in my personal email and copy it over to an outlook invite? In my research, it looks like the limit for a meeting invite is 5000 in outlook, not 500. Can you also confirm?mccalamApr 09, 2025Copper Contributor125Views1like4CommentsTeams Live-Event with RTMP ingest
Dear all, I have a couple of questions regarding the new Teams Live-Events with RTMP ingest (using an external encoder). So far I´ve been using MS Stream live-events for professional livestreams with an external encoder and it worked great. But since the Stream live-events will be shut down at some point this year, I have to make the switch to the Teams live-events (with RTMP ingest). Is there an option to disable all automatic audio enhancement functions (like noise reduction, etc.)? If I stream music/spoken language to the live-event it doesn´t sound as good as with the Microsoft Stream live-events. Do teams live-events with RTMP ingest offer a buffer in case one of the viewers has an internet problems? Because to me it seems like the RTMP In live-events work rather like a general Teams Video-Call, so that in case of internet problems the audio will still be audible and the image will freeze. Usually streaming platforms have a buffer that will be filled to prevent audio-video dropouts. How do live-events in MS Teams in general differ from the live-events in MS Stream? Thanks in advance for your help! Best regards.Broadcast345Apr 02, 2025Copper Contributor967Views1like1CommentAudio quality when using Teams Townhall with rtmp-in.
Hi everyone I have broadcast a live music (orchestra) concert using Teams Townhall with rtmp-in (using Blackmagic Design web presenter). When I checked the archive recorded on Teams, I realized that the volume of the music is being ducked automatically. All my audio sources are mixed down with a professional digital mixer before streaming to Teams so basically they have a good balanced. I have another back-up recorded data and it does not have the same problem, so i think it is caused by the algorithm of Teams, and even if I am using an external encoder?? Is there a method to fix this problem? I have compared the data recorded by the external device and teams. The ducking is quite obvious. Lower: Recorded on Teams Townhall Thank you Cheers CarsoninitialcApr 02, 2025Copper Contributor79Views0likes0Comments
