Alert Message
Single Global Catalog in topology
<Details>
<Content>
For fault tolerance, it is a best practice to have at least two global catalog servers available to service Exchange Servers and users. A single global catalog server represents a single point of failure If a global catalog server is not available, mail delivery can slow or stop completely. Also, if a global catalog server is not available, Exchange Server services may not start. If Exchange Server services do not start, users cannot access their mailboxes.
