Hi I have admin rights. But when try to send message to users through task manager a message comes " Your message to user X ( sessionId=2) could not be sent. Access is denied. I think it has to do something with group policy settings. It was working fine previously. Can anyone advice which policy settings affected this ?

Hi Kim Thanks. Under process from all users I could not find User prompt ?

Hi, As you have not encountered the UAC prompt, please just ignore it and go to step 4. Let me know if it works. Kim Zhou TechNet Community Support
