Why You Should Kill ActiveSync (and How to Do It)

To kill Microsoft ActiveSync when it hangs on a Windows desktop, use Task Manager to terminate WCESMgr.exe or WCEComm.exe, or use the taskkill command in Command Prompt. For server-side issues, administrators can recycle the MSExchangeSyncAppPool in IIS or disable ActiveSync for specific users via Exchange Management Shell. For more details, visit Microsoft Learn.
