What is MMGAServer?

Question

_{Thursday, May 3, 2018 10:35 AM}

I've got a client who has an issue with an EXE not starting, and looking at the wait chain in Resource Monitor it's waiting on MMGASERVER.EXE.

If I kill MMGASERVER.EXE, the program continues and starts up fine.

There are three apparent components to this MMGASERVER, in c:\windows\syswow64\ as follows:

29/09/17  14:42         1,428,480 mmgaclient.dll
29/09/17  14:42            62,976 mmgaproxystub.dll
29/09/17  14:42         1,060,352 mmgaserver.exe

Since those three files are also present on a Windows 10 VM that I have here, I'm assuming they're part of Windows itself.

Googling only throws up a million stupid 'fix your PC' sites, and also malware forums where people have listed the contents of their Windows folder.

So what I'm asking is what do these files do ?

Sorry, I don’t know, I search in our library channel, no record.

According to the description, it is a MMGA server, but no other explanation.

You know, Windows is an encapsulated system, mmgaserver.exe as a system component doesn’t have any introduction in public, therefore we can’t know what this file do, please understand.

Regards

Okay, it's stopping our application working so how do I go about addressing that if MSFT can't even tell me what it does?

looking at the COM interface IMMGAServerStub in "c:\windows\syswow64\mmgaserver.exe", it seems to be used for sending / receiving mail via MAPI.

When this is your Application: why don't you simply look at the call stack?
