SUMMARY
This article describes how to use the Setup /r switch to install Microsoft Exchange Server 5.5.

MORE INFORMATION
When you install Exchange Server on your computer, it is possible to run the Setup.exe program with the /r option. This option was originally designed to be used to install Exchange Server without creating full copies of the Exchange Server databases.

When you use this option, an incomplete version of the directory service database (Dir.edb) is created. This database cannot successfully create private and public information store databases (Priv.edb and Pub.edb). Therefore, you should only use the Setup /r switch when you are installing Exchange Server and are planning to restore your directory (Dir.edb) from an online or offline backup file.

If you have used the Setup /r switch to install Exchange Server and you are not planning to restore your directory (Dir.edb) from an online or offline backup file, you need to remove the current installation from Exchange Server. You then must install Exchange Server without using the Setup /r switch.

In addition, if you have installed Exchange Server using the Setup /r switch, you are not able to run the Performance Optimizer until you have restored the Exchange Server databases. Also, you cannot apply any Exchange Server service packs until you have restored the Exchange Server databases.

It is not recommended that you use the Setup /r switch to install Exchange Server, because there are no benefits to using this switch, nor is this method faster than the regular installation process.
