Exchange Server 2007 should be configured with 64-bit hardware in a production environment. Generally speaking, 32-bit Exchange 2007 can only be used for testing, evaluation, or training. But that's not all right. It is possible to configure a 32-bit version (or E2K7/32) to be used as an available server in a supported manner-only limited functionality on Exchange 2007.
Here are some concise outlines of what is possible and what is not possible in the 32-bit version of Exchange 2007.
1. Can be used to manage other 64-bit Exchange2007 systems. This functionality can be achieved by installing a windows2003 system with 32-bit systems or by a Windows XP system. (If Windows Vista System and Windows server2008 system, you have to install the Exchange2007 service Pack1 patch to support.) )
2. Under the product environment, Active Directory Active Directory service plans can be extended.
3. Supports a single replica cluster and cluster continuous replication, but only between 32-bit versions, not in the product environment. These two features are defined in the 32-bit version of the Enterprise Edition, but in fact they are just nominal.
4. Support Unified Messaging (UM), but can only be done in a non-product environment.
5. There is no Exchange Management Console section to enter the product key because you are purchasing a serial number of exchange with less than 32 digits.
6. Automatic anti-spam patches cannot be obtained from the Microsoft patch server, and only 64-bit Exchange2007 can get those patches.
7. Only connections to 5 databases per server and 5 Exchange storage groups can be supported.
8. Only the standard version of the said, and no enterprise version of one said. (This is the exception to the two features of a single replica cluster and cluster continuous replication, and these two features are some of the features of the Enterprise Edition.) )
