Tag someone in the QnA

In Microsoft Q&A there is no built‑in way to @mention or tag a specific user in a post or comment. The tagging/mention feature described in the context applies to Office documents (Word, Excel, PowerPoint) stored in SharePoint or OneDrive, not to Q&A.

On Q&A:

• Tags are used only to categorize questions by product/topic, not to notify individual people.
• Replies are associated with the account that posted them, but other users cannot be directly tagged or notified from within a reply.

To continue a conversation with the person who answered, reply under their answer or comment on it; they will receive notifications based on their own Q&A notification settings.
