Baseline Collection Rule for SMTP Server Categorizer Queue

Microsoft.Exchange.Routing.Queue.SMTPCatQueue.BaselineCollection (Rule)

This rule collects the baseline performance metric for SMTP Server - Categorizer Queue

Knowledge Base article:

Summary

Categorizer is part of SMTP. The categorizer queries the Active Directory for recipient mailbox information, distribution list expansion, and so on.

This baseline collection is used by the Self-Tuning threshold monitors and must not be disabled unless the associate threshold monitor is disabled as well.

Causes

The Categorizer queue may increase due to its inability to query Active Directory.
