Posted by admin on 04.12.2019

Exchange 2016

McAfee Security for Exchange 8.6 SP2 (Safeservice.exe, RPCserv.exe (two instances), Postgres.exe (multiple instances))

D:\Program Files (x86)\McAfee\MSME\bin\SAFeService.exe

Server 2016

Source was: C: had no space in test lab server

If you see random Files with 96’201’998 (96MB) size under “C:\Windows\Temp\SAFe\” on your Exchange 2013/2016 those are from McAfee Security for Exchange 8.6. The shown server was a test lab running for long times a space on c: Drive did run out because it was unattended. You also see the “SAFe” directory under “D:\Program Files (x86)\McAfee\MSME\bin\lang\0409\SAFe”

Problem is finding something about thise issue since 99% google result end up in is it “safe” to delete “c:\windows\temp” 😉

See such files since Ransomware so maybe this helps someone once.

This event (IF your send E-Mail Alerts) should help too.
