Microsoft 365 Copilot Can’t Respond to Sentiment-Related Prompts
I must admit that reading message center notification MC1246010 (“Transitioning Microsoft Teams Copilot to Microsoft 365 Copilot chat and impact on Limited Mode”, published 6 March 2026) caused me to expend more brain cells than it should have, mostly because I didn’t understand what limited mode means, despite writing about the topic in December 2024. I guess this is a side effect of age.
Copilot Consolidation
The first part of the topic is straightforward. The Copilot implementation for Teams meetings is being replaced by Microsoft 365 Copilot as part of the effort to consolidate Copilot interfaces within Microsoft 365. Teams has its own way of interacting with Copilot in meeting chat, probably because when Microsoft first introduced Copilot in 2023 development teams experienced huge pressure to incorporate AI in their products. There wasn’t a lot of joined-up thinking, and the joke was that developers created over 150 different Copilot implementations in the months following the grand announcement in March 2023.
Consolidation has already started and is expected to be complete worldwide in the third week of March 2026. I doubt users will notice the difference, except when they suddenly discover that attempts to ask Copilot about certain topics are now blocked.
Copilot Limited Mode
Because Teams meetings had its own way of dealing with Microsoft 365 Copilot, and because emotions often surface during meetings and are visible to all meeting participants, Teams introduced a setting to control Copilot responses in December 2024. The setting determines whether Copilot generates responses to “sentiment-related prompts.”
If the setting contains the identifier for an Entra ID group, Copilot extracts the membership of that group and won’t respond to sentiment-related prompts. In other words, Copilot won’t respond with opinions, emotions, evaluations, or judgements when prompted by one of the blocked users. For example, if a blocked user asks Copilot about the meeting participant who made the most positive contribution, Copilot politely declines to comment. This is what Copilot Limited Mode refers to (Figure 1).
As part of the consolidation, Microsoft has decided to extend the “protections” (against hurting peoples’ feelings) to all users instead of members of a specified group. Apparently, the decision is in line with Microsoft’s Responsible AI Principles to block AI generation related to worker performance evaluation and judgments about human emotion.
/re Because Copilot Limited Mode no longer needs to be configured, Microsoft will retire the Copilot admin limited mode Graph API on March 19. The Graph API is the PowerShell API for configuring limited mode referred to in MC1246010. I guess you can configure the setting with PowerShell, so everything is good. No further action is necessary because the API will simply disappear.
Seeking Knowledge About People
There’s not much else to say about this change. As noted above, users probably won’t notice the transition unless they’ve been used to asking Copilot about the sentiment of other meeting participants and now become frustrated with the lack of Copilot responses. I doubt that such an issue will be brought to a help desk.
Imagine the help desk worker faced with a question like “I used to ask Copilot whether my manager was happy during a meeting and now Copilot won’t tell me…” I’m not sure what the reply might be, apart from advising the user that perhaps they could ask their manager in person about their happiness level. But then again, that’s embarrassing, and it’s always easier to ask those kinds of questions to a computer.
