Hi @Bishal Murmu, 

Thank you for reaching out Microsoft Q&A Forum and for your detailed question regarding user mentions in 1:1 personal scope bot chat in Microsoft Teams. 

I’d like to confirm that, as of today, user mentions are not supported in personal scope (1:1) bot conversations. This is a current platform limitation in Microsoft Teams. In these chats, the mention picker (triggered by typing @) does not appear, and even manually constructed mentions will not resolve unless the mentioned user is part of the conversation — which is not possible in personal scope. 

To summarize: 

• Mentions are supported in channels, group chats, and user-to-user chats. 
• Mentions are not supported in user-to-bot personal chats. 

There are no available configurations in the Teams app manifest, Microsoft Graph API, or Teams admin settings that can enable this functionality in personal scope at this time. 

We understand this may impact certain use cases, and while there is currently no public roadmap for this feature, I encourage you to submit feedback through your Microsoft 365 admin or via the Teams Developer Support channels. Feedback from developers like you plays a key role in shaping future improvements. 

You can submit feedback to our product team on your behalf to request an increase in the participant limit for Teams group chats in future updates.     

Go to: Microsoft 365 Feedback Hub →Send Feedback→ Describe your proposal in detail       

Sharing your experience through this channel is the most impactful way to advocate for a change that would benefit you and other users. Your feedback helps our product teams better understand what matters most to users and prioritize improvements accordingly.  

If your scenario requires referencing or notifying other users, you might consider using a group chat or channel-based interaction, where mentions are fully supported. I’d be happy to help explore alternative approaches if needed. 

Thank you again for your patience and for bringing this to our attention. While I can't change the product's design, please don't hesitate to reach out if you have any other questions about its current functionality.    

Warm regards,
