MAILMBXSTATE - Mailbox Session Interrupted During Sync

Error CodeMAILMBXSTATE
Error MessageThe mailbox session was interrupted. The server closed the connection during an active sync.
SeverityMedium
AffectsIncoming Email Servers

Symptoms

  • Email sync stops partway through and the connection is reported as closed by the server.

Root Cause

  • The mail server closed the connection while ServiceOps was actively syncing.
  • This can happen due to a server-side timeout, or another application accessing the same mailbox at the same time.

Resolution

  1. No immediate action is required. ServiceOps reconnects and retries automatically on the next polling cycle.
  2. If this error occurs frequently, check whether another application is connected to the same mailbox simultaneously. Limiting the mailbox to a single connection reduces session interruptions.
