📎 AI Summary:
The thread concerns a Microsoft Teams live-caption pop-out window that continues displaying captions but becomes immovable after being repositioned, affecting multiple users despite cache clearing, reinstallation, and reboots. The response suggests a likely Teams UI regression, recommends testing by closing/reopening or resizing the window and checking environment details, and advises collecting logs and escalating through the Microsoft 365 administrator; no confirmed Microsoft advisory or resolution is reported.

Recently a user put in a ticket stating that the live caption box in Microsoft Teams freezes in place after popping it out during a call.
it used to be able to drag it anywhere on the screen, now after a few movements it's just stuck. the captions continue to work during the call but the window can't be moved.
the call window can move.
I've tested this with 4 other people, and the results are the same the caption box freezes in place.
I've cleared the teams cache, I've uninstalled teams and reinstalled, and rebooted nothing seems to fix it.

any help would be appreciated.

Larry, the key detail is that captions keep updating, but only their pop-out window stops moving. Given that you reproduced it with four other people and reinstalling didn’t help, I wouldn’t repeat the cache clearing or reinstall.
Microsoft still documents the caption window as independently movable and resizable, so this isn’t expected behavior. A Teams UI regression is a reasonable hypothesis, but I couldn’t find a public Microsoft advisory confirming this exact issue. (support.microsoft.com)

Next steps​

  1. Try the simplest workaround: close only the caption pop-out window. Microsoft says this returns captions to the meeting window. Leave them docked for now, or select Open captions in new window again and check whether movement temporarily returns. (support.microsoft.com)
  2. Check what still responds when it gets stuck. Can you resize the caption window by dragging its edges? Do its settings and close controls still work? Also try reproducing it while keeping the window entirely on one monitor, without crossing screen boundaries. These tests will help distinguish a dragging-only problem from a broader window-interaction problem.
  3. Compare the affected environments. Please share the exact Teams version, Windows version/build, and approximate date it first started. Are all affected users in the same organization, and are they using local desktops or a remote/VDI environment? For multiple-monitor setups, include each monitor’s display scaling percentage.
  4. Capture evidence for escalation. On an affected Windows desktop, reproduce the issue, note the time and time zone, then press Ctrl + Alt + Shift + 1 while Teams has focus to collect support logs. Microsoft saves these in Downloads and recommends collecting them immediately after the problem occurs. Share logs privately with your IT team/Microsoft Support, not publicly in the thread, since they can include diagnostic information for all signed-in Teams accounts.
With the same behavior across several users, I’d have your Microsoft 365 administrator check tenant Service health and open a support case with those versions, reproduction steps, and a short recording from a test call.
Does closing and reopening the caption pop-out restore dragging, and can you still resize it once it becomes stuck?
