I had the same problem yesterday at 23PM!
Event ID: 7036 - The Microsoft Filtering Management Service service terminated unexpectedly. It has done this 14 time(s).
Event ID: 1106 - The FIP-FS Scan Process failed initialization. Error: 0x80004005. Error Details: Unspecified error
Event ID: 5300 - The FIP-FS "Microsoft" Scan Engine failed to load. PID: 61872, Error Code: 0x80004005. Error Description: Can't convert "2201010001" to long.
I tryed this, but no success:
Add-PsSnapin Microsoft.Forefront.Filtering.Management.Powershell
Get-EngineUpdateInformation
cd "C:\Program Files\Microsoft\Exchange Server\V15\Scripts'
$Computer = $ENV:ComputerName
.\Update-MalwareFilteringServer.ps1 -Identity $Computer
I used this workaround yesterday temporarily:
Get-TransportAgent "Malware Agent" | Disable-TransportAgent -Confirm:$false
Stop-Service msexchangetransport
sleep 5
Start-Service msexchangetransport
Get-TransportAgent "Malware Agent"
Any fix?
