I have for some time tried to solve an anoying problem I've had after a
migration
to Exchange 2003.
Using CDO 1.21 on an active server page application, the application can be
used to acces
a the calendars of a group of known users.
The application was also moved to a new web server.
I'm aware of the limitations of CDO (the rendering objects) and do not use
any of that.

Several places I use code like

Set objSession = CreateObject("MAPI.Session")
objSession.Logon "", "", False, True, 0, True, sHost & vbLf & "SMTP:" &
sMailBox & "@" & sDomain

and right after the 'Logon' call the MAPI_E_NOT_INITIALZED exception is
thrown.
The explanation of the exception is that it occurs if the the session object
is used without the logon have been called.
This is clearly not the case here.

The funny part is, that if I take the same code and run it as a VBScript
from the commandline (on the web server),
it works fine and no MAPI_E_NOT_INITIALZED is thrown.

HELP!!

The problem is that the session doesn't actually do the login until you
try and do something with the session that needs the login to have
happened. So if you do, say:

oSession.Logon ...
.. some other code ..
Folder f = oSession.Inbox ' This is when the actual logon happens

That's why you're seeing the error.

Are you running as the same user as the web server user? For some more
tips on using CDO1.21 from ASP, see:

Sorry, I probably wasn't precise enough expressing my question.
The exception doesn't happen after, but during or at the call af the
oSession.Logon.
The 'Folder f = oSession.InBox' part is never called.

Each time I've seen this, it's been caused by a problem with the CDO
ProfileDirectory:

http://support.microsoft.com/default.aspx?scid=kb;en-us;166599

If you have created this profile directory, then make sure that the account
you are running the script as has permission to create/delete files in it.

Well I have already tried this one. But apparently with no help. The Temp
folder used to
store the MMP files have everyone full control.

I also think that if this was an issue, the problem should be the same
wether you run it by
the WEB-app or by the command line script.

And by the way I use Basic authentication on the web-page, and do the tests
logged in as the same user when running the command line script as well on
the
web page.

IIS only reads the registry value once - the first time it needs it. A
script might read it each time it is run (although I don't actually know if
it would, or not). If you tried your CDO app before the registry key had
been created, you would need to stop/start IIS otherwise it will continue to
try and put them in the server's system directory C:\WINDOWS.

It might be worth using filemon to see if any mmp files are being
successfully created.

Lee, I am having the same problem.
The Intranet site is trying to access a public store contact folder on
Exchange 2003.
I'm trying to move an Intranet site to a new W2K3 Server (from W2K Server)
but this error is making me crazy too.
I have set all permissions, changed registry settings, even changed
anonymous login to administrator for both local mahcine and domain. I used
iisreset as and even restarting server completely after all changes to make
sure nothing was remembered.

Just as Olesen, I can put it in a vbs file and it works perfectly although
the Outlook client prompts me to allow permission.

This code for gives 500 Internal Server Error

Dim objSession
Set objSession = Server.CreateObject("MAPI.Session")
if objSession is nothing then
response.write "Not working...?"
else
response.write objSession.username
end if

Origianl Code gives MAPI_E_NOT_INITIALIZED error at the logon

const ServerName = "HPT-MX1"
const UserName = "Administrator"
Set objSession = CreateObject ("MAPI.Session")
strProfileInfo = ServerName & vbLf & UserName
objSession.Logon "", "", False, True, 0, False, strProfileInfo

Even if I do nothing after the logon I still get the error.
