DOCUMENT:Q166349 14-JAN-2001 [exchange] TITLE :XGEN: Exchange Server, Client, and Outlook Version Numbers PRODUCT :Microsoft Exchange PROD/VER::4.0,5.0,5.5 OPER/SYS: KEYWORDS:exc4 exc5 exc55 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 - Microsoft Exchange Windows 3.x client, versions 4.0, 5.0 - Microsoft Exchange Windows 95/98 client, versions 4.0, 5.0 - Microsoft Exchange Windows NT client, versions 4.0, 5.0 ------------------------------------------------------------------------------- SUMMARY ======= The following article lists all versions of Microsoft Exchange Server, Exchange Client, and Outlook software that have been released to date and how to determine which version or versions are currently running. MORE INFORMATION ================ Determining Exchange Server Versions ------------------------------------ 1. Start the Microsoft Exchange Administrator program. 2. In the left pane, select the Exchange Server. 3. On the File menu, click Properties. The version, build number, and any service packs that are installed are displayed. NOTE: Selecting help/about from within the Administrator program gives the version of Admin.exe and may be misleading if you are running the Administrator program against a different Exchange Server computer or from a Windows NT Workstation. Determining Exchange Client Versions ------------------------------------ Select help/about from within the Microsoft Exchange Client. NOTE: From Windows 95 or Windows NT, you may be able to determine which version is installed by selecting properties for a particular file from Windows (NT) Explorer and selecting Version. Microsoft Exchange Server service packs are posted at the following address: ftp://ftp.microsoft.com/bussys/exchange/exchange-public/ Here is a list of Exchange versions numbers and their associated Build numbers: Version Build Number ------------------------------------ 4.0 RTM 837 4.0 SP1 838 4.0 SP2 (Exchange 4.0a) 993 4.0 SP3 994 4.0 SP4 995 5.0 RTM 1457 5.0 SP1 1458 5.0 SP2 1460 5.5 RTM 8.03.4629 (due to the switch to the Outlook Client) 5.5 RTM 1960 5.5 SP1 2232 5.5 SP2 2448 5.5 SP3 2650 5.5 SP4 2653 The Windows Messaging Client that ships with Windows NT version 4.0 also has a build number of 837, the same as Exchange 4.0. The splash screen, however, is entitled Windows Messaging, not Microsoft Exchange. The Windows Messaging client that ships with Windows 95 is build 950. Neither of these clients provide connectivity to an Exchange Server and must be upgraded to one of the versions listed in the table above to work with Exchange Server. Determining Microsoft Outlook Versions -------------------------------------- 1. Start Outlook. 2. On the Help menu, click About Microsoft Outlook. Here is a list of Outlook clients with their version numbers and build numbers: Outlook client for Windows 3.1: 8.0.1960.0 Outlook 97 (shipped with Office 95): 8.0 Outlook 97 (shipped with Exchange 5.0 sp1): 8.01.3817 Outlook 97 with Office Service Release 1: 8.02.4212 Outlook 97 (shipped with Exchange 5.5): 8.03.4629 Outlook 97 with Office Service Release 2: 8.04.5619 Outlook 98 : 8.5.5104.6 Outlook 2000: 9.0.0.2711 The version and build number are in brackets at the top of the dialog box. Additional Information About Service Packs ------------------------------------------ Microsoft releases service packs for Microsoft Exchange on a regular basis. Microsoft recommends running the latest service packs on all servers and clients whenever possible, but it is not required that all Exchange Servers or Clients be simultaneously upgraded to the same service packs (although this may be ideal). In general, Microsoft Exchange service packs are cumulative, that is, each service pack contains all fixes up to that point. This means that in order to bring an Exchange Server or Client up to a SP level, the earlier SP doesn't need to first be installed. The exceptions to this rule are Exchange 4.0 service packs later than SP2. Due to the size of Exchange 4.0 SP2, subsequent SPs were created as deltas only. To bring an Exchange Server or Client up to a later 4.0 SP, SP2 needs to be first applied. As with any major software rollout, Microsoft recommends that you install service packs on a non-production (test) computer first and test similar functions to those that your production server/client encounters. Always read the release notes (usually Readme.wri) prior to installing the service pack into production.
