Hello Saurabh,
About sending emails to the one who has been mentioned, it isn’t feasible. And users can only set and control their own mention notifications. In Teams, you can turn on Banner and emails for Mentions, if there’s
any missed mention activity, you’ll be receiving an email:
If you can’t get the email, then set the “Missed activity emails” to “As soon as possible”:
Based on my experience, emails will send to you only when you aren’t signed in. If you have different scenario, or any concerns, please feel free to let me know.
Besides, for this feature, if it’s very important to you, I recommend you submit a feedback at
Teams UserVoice. We highly value every customer’s suggestions to the product, your time and understanding will be greatly appreciated.
Best Regards,
Anna
