Hello @thesia122,
Thanks for creating a support topic. I have tried to delete the user associated with the weMail’ Teams. I was able to delete it from the Users ( WP Admin->Users ) successfully. After the user is deleted, the current status of that user from the weMail->Teams are being Disabled.
Could you please share more details with screenshots on the scenario, like from where you are trying to delete the user and how the user is connected/associated with the weMial?
