Determining if Enterprise or Standard edition

Determining if Exchange Server Enterprise or Standard Edition is installed

SYMPTOMS
There is no distinction in the user interface between Exchange Server Standard and Exchange Server Enterprise editions.

CAUSE
This is by design.

WORKAROUND
To distinguish between Exchange Server Standard and Exchange Server Enterprise, check the Windows Event Viewer application event log upon startup.

The following event is logged when the information store starts on an Enterprise edition Exchange Server computer:

Event Id: 1217
Source: MSExchangeIS
Type: Information
Category: General
Description: "Information store with unlimited capacity started"

The Standard edition logs the following event:

Event ID 1216
Source: MSExchangeIS Private
Type: Information
Category: General
Description: Information store with limited storage capacity enabled.

APPLIES TO
? Microsoft Exchange Server 2003 Standard Edition
? Microsoft Exchange Server 2003 Enterprise Edition
? Microsoft Exchange 2000 Server Standard Edition
? Microsoft Exchange 2000 Enterprise Server
? Microsoft Exchange Server 5.5 Standard Edition

The easiest way is to open the properties for your server in Exchange System Manager (ESM), and on the General tab if you see the option "This is a front-end server" then your running Enterprise, otherwise you are running Standard.

Note for Exchange Server 2003: In Exchange 2003 method #1 no longer works because Exchange 2003 Standard Servers can also act as Front-End servers, which was not true in Exchange 2000
