# How does update or delete comment functionality works in Team Foundation Server (TFS) and Azure DevO

### Description

Azure DevOps systems provide the feature to edit and delete operation in comments.

### Solution

You can edit or delete discussion/comment from the systems’ User Interface.\
But right now <code class="expression">space.vars.SITENAME</code> does not provide this feature.\
Once any comment is created in Azure DevOps systems, it will not be updated or deleted by <code class="expression">space.vars.SITENAME</code>.
