SUMMARY
Exchange 2000 does not support the &quot;other users&quot; namespace in the Internet Message Access Protocol 4 (IMAP4) protocol namespace command. This functionality is available only in Exchange Server 5.5. When you open an IMAP4 connection on port 143 (default port number) to an Exchange server, log on with a user name and password, and then run the namespace command, Exchange Server 5.5 returns the list of name spaces including the other users' name spaces (delegated users). Exchange 2000 only returns the name space for the current user.



MORE INFORMATION
Note the output you receive when you run the following commands:

telnet  143

a001 login

a002 namespace

In Exchange 2000, you receive the following output:


 * NAMESPACE ((&quot;&quot; &quot;/&quot;)) NIL ((&quot;Public Folders/&quot; &quot;/&quot;))

In Exchange Server 5.5, you receive the following output:


 * NAMESPACE ((&quot;&quot; &quot;/&quot;)) ((&quot;Other users/&quot; &quot;/&quot;)) ((&quot;Public Folders/&quot; &quot;/&quot;))
