From the screenshot, the Communication Panel is in its popped-out (floating) mode. This is a supported UI state, not necessarily a bug.
A few points:
- Yes, users can intentionally pop out the Communication Panel by clicking the Pop out/Restore icon in the panel header (next to the minimize button). Clicking it again docks the panel back into the workspace.
- If the panel is appearing in floating mode without the user clicking the button, that is not expected behavior.
- This can sometimes occur if:
- The browser restores the previous UI state after a refresh or session restore.
- The app remembers the last panel state.
- A browser extension or custom script is interfering.
- There is a product issue in a specific Dynamics 365/Customer Service workspace build.
Recommended troubleshooting
- Confirm whether users can reproduce it consistently with specific steps.
- Test in an InPrivate/Incognito browser session with extensions disabled.
- Test in another supported browser.
- Verify whether the issue occurs for all users or only specific users.
- Check the environment version and see if the issue persists after applying the latest Microsoft updates.
