The genuine fixmapi.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation. "Fixmapi.exe" was a Microsoft utility program last usable with Windows 7 or Windows Server 2008 but it still exists in Windows 10 in "C:\Windows\System32". (64-bit Windows has a 32-bit "fixmapi.exe" in "C:\Windows\SysWOW64".) It ran from the command line without parameters. It restored the Messaging API, "mapi32.dll", from a "stub" version named "mapistub.dll". Since Windows Vista, the standalone utility is replaced by a linkable "fixmapi" function within the "mapistub.dll". MAPI makes applications "email-aware" to interact with Microsoft Exchange. Different applications installed customized versions of "mapi32.dll" over the original which had to be restored if the app was uninstalled.
FixMAPI stands for Fixing Utility for Windows Messaging API DLL
