INTRODUCTION

This article describes how to determine which edition of Microsoft Exchange Server is installed on the computer. There is no difference in the user interface between Exchange Server Standard Edition and Exchange Server Enterprise Edition.

MORE INFORMATION

To determine which edition of Exchange is installed on the computer, use one of the following methods.

Method 1: Examine the Application log

This method applies to Exchange Server 5.5, to Exchange 2000 Server, and to Exchange Server 2003.

Exchange Server Standard Edition has a limited information store. Exchange Server Enterprise Edition has an unlimited information store. To distinguish between Exchange Server Standard Edition and Exchange Server Enterprise Edition, examine the Application log after Microsoft Windows is started.

The following event is logged in the Application log when the Microsoft Exchange Information Store service starts on a computer that is running Exchange Server Standard Edition:

Event ID: 1216
Source: MSExchangeIS Private
Type: Information
Category: General
Description: The information store database <database location> has limited storage capacity enabled.

Note In Exchange Server 5.5, the description of event ID 1216 is "Information store with limited storage capacity enabled."

The following event is logged in the Application log when the Microsoft Exchange Information Store service starts on a computer that is running Exchange Server Enterprise Edition:

Event ID: 1217
Source: MSExchangeIS
Type: Information
Category: General
Description: The information store database <database location> has unlimited storage capacity enabled.

Note In Exchange Server 5.5, the description of event ID 1217 is "Information store with unlimited capacity started."

Method 2: Examine the registry information

You can examine the registry information to determine which edition of Exchange is installed. This method applies to Exchange 2000 and to Exchange 2003.

Determine which edition is installed

  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate the following registry key:
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
  3. Find the appropriate GUID registry subkey in one of the following lists. Verify that the DisplayName in the right pane is Microsoft Exchange 2000 or Microsoft Exchange.
    • The following subkeys indicate the version of Exchange 2000 that is installed on the computer:

  4. Quit Registry Editor.

Product version summary

  • Full Packaged Product (FPP) This is a complete product that has no limitations.
  • Version Upgrade Package (VUP) This is an upgrade from an earlier version of the product to the current version of the product. An example of a VUP upgrade is an upgrade from Exchange Server 5.5 Standard Edition to Exchange Server 2003 Standard Edition.
  • Product Upgrade Package (PUP) This upgrade applies only to a product of the same release. An example of a PUP upgrade is an upgrade from Exchange 2000 Server Standard Edition to Exchange 2000 Server Enterprise Edition.
  • Evaluation Edition (EVAL) This is the same as the FPP version. However, the EVAL version expires 120 days after it is installed.
Important If you manually uninstall Exchange, the corresponding registry key that is specified in step 3 of the "Method 2: Examine the registry information" section still exists. Additionally, Exchange is represented by Microsoft Exchange version in Add or Remove Programs. If you delete one of the registry keys that are specified in step 3 of the "Method 2: Examine the registry information" section, Microsoft Exchange version is removed from Add or Remove Programs.

Method 3: Examine the Type attribute

Whether an Exchange Server 5.5 information store is unlimited is determined by a new, non-editable directory attribute called Type. The Type attribute is encoded.
Note When the information store reaches the 16-gigabyte (GB) limit on a computer that is running Exchange Server 5.5 Standard Edition, the following event may be logged in the Application log:

Event ID: 1112
Source: MSExchangeIS
Description: The database has reached the maximum allowed size. Attempting to stop the Microsoft Exchange Information Store.

How to change the Type attribute

The Type attribute can be changed only if you run Setup.exe from an Enterprise Edition CD and choose the Reinstall option. Note that you must run SrvRmax.exe if you are using a Select CD. When you run Setup.exe and choose the Reinstall option, the Type attribute is changed in the Dir.edb file to give you an unlimited information store.

Note After you run Setup.exe to reinstall Exchange, you must reapply the last Exchange service pack that you applied before you reinstalled Exchange.
