You install a multi-user setup of Notes client, and during the installation you are prompted only for where you would like to install the Notes program directory; you are not asked to specify the location of your Data directory. You then log onto the machine, run through the Setup and this creates the personal data folder in the default location of:
C:\Documents and Settings\[user name]\Local Settings\Application Data\Lotus\Notes\Data
If another user logs onto the computer and runs through the setup, the same behavior occurs, only under that user's account. Users are not given a choice at any time through install or setup to specify a different location for their Data directories.
Support was introduced in Notes 8.5.1 for custom data directories using properties MULTIUSERBASEDIR and MULTIUSERCOMMONDIR. For details,see the following Wiki article: Configuring custom data directories for multi-user install or upgrade on Windows
An enhancement request for this new functionality was tracked under SPR# KTOT5G3MQZ. There are no plans to add this functionality in the 6.5, 7 or 8.0 code streams.
In one particular case, an administrator wanted to lock down computers to the users and give them rights only to the "My Documents" directory. Ideally he wanted their Data directories installed there. The directories could be moved after running through the setup; however, this defeats the administrator's purpose of locking the directories and giving the users limited rights.
Setup.exe /v"SETMULTIUSER=1 MULTIUSERBASEDIR=\"C:\Documents and Settings\!user name!\My Documents\" MULTIUSERCOMMONDIR=\"C:\Program Files\IBM\Lotus\Notes\Data\" "
Another reason administrators may desire this functionality is because the Local Settings folder does not roam via Windows OS Roaming Profiles. If you are using Roaming Profiles you may want to alter location of the multi-user Data directory in order to use this OS feature in conjunction with Notes Data directories.
Setup.exe /v"SETMULTIUSER=1 MULTIUSERBASEDIR=\"C:\Documents and Settings\!user name!\Application Data\" MULTIUSERCOMMONDIR=\"C:\Program Files\IBM\Lotus\Notes\Data\" "
