What is mqsvc.exe?

The genuine mqsvc.exe file is a software component of Microsoft Message Queuing by Microsoft Corporation.
"Mqsvc.exe" is a Microsoft Windows core file, located in "C:\Windows\System32", implementing the Microsoft Message Queuing (MSMQ) messaging protocol. This service begins at Windows startup and always runs in the background. It cannot be uninstalled unless the Windows OS is, but it can be turned off. It is used in Windows Server and Windows endpoint PC operating systems, but not in Exchange Server. Using three different communications protocols, (TCP, RPC, and UDP), which employ both TCP and UDP ports, it enables applications to place messages in temporary storage for retrieval by other applications across networks and between computers whether or not a direct connection exists when the message is sent. It is commonly used in enterprise applications developed on Visual Studio and Visual Studio .NET. If Microsoft Outlook is managing multiple e-mail accounts under Windows 10, it can become unresponsive if "mqsvc.exe" is turned off.

Harmless until it resides in system32. Based on you preference and needs it can be turned off.

mqsvc.exe is a process of the Microsoft Windows Operating System, and belongs to the Message Queue Server (MSMQ). This is a non-essential process. Disabling or enabling this is down to user preference

I know it is a Windows application file, but little else

Processor intensive. Best to set the service to Manual, and, if running, to stop it.

Seems this process is needed in Outlook 2013 when using Outlook to send & receive messages with multiple e-mail accounts. This is on a Windows 10 machine with Office 2013 installed and monitoring 3 e-mail accounts. With this process turned off Outlook frequently becomes unresponsive.

Best practices for resolving mqsvc issues

A clean and tidy computer is the key requirement for avoiding problems with mqsvc. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
