Voice echoes while in use

Hi, I have installed Audacity on Windows 10. When using a medium quality microphone, a voice is recorded but echoes and feels like being in a closed room. Has anyone come across such a case?
Any help? Thanks!

Do you have Preferences > Recording > [X] Playthrough selected?

Are you listening on headphones or a speaker in the room?

Are you in a closed room?

Are you recording from the microphone or one of the settings that records “what’s playing on the computer?”

What’s the microphone and how is it connected?

Do you have Skype, Zoom, Meetings or other chat application and do you leave it running in the background?
