Hi @LERCHE, Nik,
Thank you for posting your question in the Microsoft Q&A forum.
Regarding you’re unable to use tags to mention other users in Microsoft Teams. I’d like to ask a few quick questions to better understand your situation and assist you more effectively:
- Is the issue affecting all teams or only specific teams?
- Are you a Teams admin or team owner in the affected teams?
- Have you try using Microsoft Teams on the web does this issue persist?
- If you are a Teams admin or if you are an end user please contact with the team admin to check if Is Tags enabled in your Teams policies? Go to Teams admin center then find Teams settings and check "Tags"
Thank you again for your time and understanding. While my initial response may not resolve the issue immediately, I’d like to gather more details about your situation so I can assist you more effectively.
I really appreciate your patience, and I’m here to help. Looking forward to your response!
