Overview
When attempting to start a GFI MailEssentials service, the following error is encountered:
Error 1075 the dependency service does not exist or has been marked for deletion.
Environment
- GFI MailEssentials
- All supported environments
Root Cause
This error will occur when you try to start a service which is dependent on another service. However, the dependency service does not exist or is marked for deletion. This may occur for the following GFI MailEssentials services, all of which are dependent on the Microsoft Message Queuing (MSMQ) service:
- GFI List Server
- GFI MailEssentials AutoUpdater
- GFI MailEssentials EmailSecurity Attendant
- GFI MailEssentials Anti-Virus (AV) Scan Engine
Resolution
Since the above mentioned GFI MailEssentials services are dependent on the MSMQ service, you need to ensure that the MSMQ service is installed and running before starting the GFI MailEssentials services.
