With Collaboration Data Objects (1.2, 1.21), you can log on to an Exchange Server mailbox using the ProfileInfo parameter. This article describes how to use the ProfileInfo parameter and why you would use it.
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 temporary
profile 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 name
is not the messaging user's display name, but rather the alias or account
name used internally by the user's organization.
For example, you should use "johnd" instead of "John Doe". The profile is
deleted after the Session is completed or terminated. Only applications
interfacing with the "Microsoft Exchange Server" service and no other services may use the ProfileInfo parameter. The profileName parameter is ignored if ProfileInfo
is supplied.
Reasons for Use
Use the ProfileInfo parameter in any of the following cases:
- 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.
- You do not want to run the code that is required to determine the
default profile for the current user.

- 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.

Sample Code
- Logging onto a mailbox from a Visual Basic application:
objSession.Logon ProfileInfo:="MyServer" & vbLf & "MyMailbox""MyMailbox"
- Logging onto a mailbox from an Active Server Page:
objSession.Logon "", "", False, True, 0, True, _
"MyServer" & vbLf & "MyMailbox"
- Logging on anonymously from a Visual Basic application:
objSession.Logon ProfileInfo:="/o=MyEnterprise/ou=MySite" & _
"/cn=Configuration/cn=MyServer" & vbLf & _
vbLf & "anon"
- Logging on anonymously from an Active Server Page:
objSession.Logon "", "", False, True, 0, True, _
