Getting Error while Modifying meeting options of channel meeting

Dear @Mukesh Kumar Agarwal,

Good day, and I appreciate the detailed description of your issue. I understand that you are unable to save meeting option changes for a channel meeting, such as enabling Record and transcribe automatically, because Teams returns “Something went wrong. Try again.” As a forum moderator, I genuinely wish I could directly access your account or delve into the backend systems to investigate and fix this for you. However, our role here is limited to providing general guidance and solutions that can be applied by users. 

I tried to replicate your issue in my test environment, but I was able to enable Record and transcribe for a channel meeting without any issues. From my research, this appears to be a service-side validation issue related to channel meetings, where not all meeting options are handled in the same way as they are for private meetings. The error message you shared is the strongest indication of that. When you try to change settings like Record and transcribe, Teams appears to send a full settings payload that includes EnableParticipantRenaming (a setting only allowed for private meetings). This causes the entire request to fail with a 400 error.

To help narrow this down, I recommend trying the following:

• Test the same change on a private meeting instead of a channel meeting. If it saves successfully there, that would strongly suggest the issue is specific to channel meetings.
• Try editing the same meeting options from Teams on the web.

I also want to be transparent that I did not find official Microsoft documentation explicitly stating that participant renaming is unsupported in channel meetings. However, the backend error you captured clearly states that this setting is only allowed for private meetings, which is the most direct explanation for why the save action is failing in your case.

If the issue continues, I recommend that the Global Admin in your organization create a service request with Microsoft Support. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis. Be sure to include the RequestId, ErrorSubCode 3113, and the exact backend response you captured, as those details should help the support team investigate the issue more effectively. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support 

I hope this helps clarify the situation and provides a clear path forward. If you have any updates after testing with a private meeting or another client, please feel free to share them in the comments. I will be glad to continue supporting you within the scope of my responsibilities.

I sincerely hope your issue will be resolved soon. Although I cannot directly intervene, directing you to the appropriate specialized support is the most effective assistance I can provide from my position. Thank you again for your patience and understanding. I’m looking forward to your reply.
