Description

The Logon method of the Session object has the following syntax:
objSession.Logon( [profileName] [, profilePassword] [, showDialog]       [, newSession] [, parentWindow] [, NoMail] [, ProfileInfo] )				
You use the ProfileInfo parameter of the Logon method to create a temporaryprofile for the session. CDO (1.2, 1.21) creates a random name for the profile. For an authenticated profile, use the following format for the string:
   "<server name>" & vbLf & "<mailbox name>"				
The server and mailbox names can be unresolved. Note that the mailbox nameis not the messaging user's display name, but rather the alias or accountname used internally by the user's organization.

For example, you should use "johnd" instead of "John Doe". The profile isdeleted after the Session is completed or terminated. Only applicationsinterfacing with the "Microsoft Exchange Server" service and no other services may use the ProfileInfo parameter. The profileName parameter is ignored if ProfileInfois supplied.

Reasons for Use

Use the ProfileInfo parameter in any of the following cases:
  1. You do not know what profiles exist on a computer or you do not want to rely on them being there. This is very common when you run code from a Windows NT Service or Active Server Page.
  2. You do not want to run the code that is required to determine the default profile for the current user. For more information abiyt determining the default profile, click the following article number to view the article in the Microsoft Knowledge Base:

  3. You want to allow users the ability to log on to the Exchange Server without an authenticated Windows NT account and have anonymous access to Public Folders.
