PSIcapture Fusion / Mailroom Service Crashes / Won't Stay Running - Windows Credentials Issue

Problem: The Fusion Services, or Mailroom Services (3.3+) continually crash and/or won't stay running when the Administrator attempts to run them from the Services console.

If the PSIcapture Fusion / Mailroom installation was deployed in an environment that restricts user creation, or the "Fusion" user was edited, removed or the account's permissions were changed post-installation, this could cause a variety of problems. For information regarding the Website File and Application Pool via IIS, see:
