CtrlSync troubleshooting

Pages here are titled by symptom — what you see — rather than by cause.

  1. Read the application status in M-Files Admin. CtrlSync reports configuration errors there directly, and a missing or wrong setting shows up as an error rather than as silence.
  2. Has the Entra ID client secret expired? Synchronisation stops with an authentication error and nothing warns you in advance.
  3. Is the connection active? A connection that is not in an active state is skipped, which looks identical to a connection that is failing.
  4. Is it still working through a batch? A large first synchronisation continues past the scheduled window by design.
