CDO hanging on Logoff


M

Matt Williamson

I can't figure out why the CDO session is hanging on Logoff for the
following code. I've read about the bug here:
http://support.microsoft.com/?kbid=177630 I've tried many different
variations but the results are the same. It was running fine using the
Outlook object model but I wanted to Delete without dumping into my Deleted
items or moving it to the journal box deleted items and emptying it
afterwards so I added the CDO bit. I've obviously changed the params for the
DN of the exchange server for this post. I'm running Outlook 2003 sp2 with
Exchange 2003 sp2. Does it make any difference that I'm opening the Journal
mailbox in addition to my mailbox? It hangs if I skip logoff and set
objCDOSession=Nothing too.

Most likely you still live MAPI objects used by CDO object at the time when
you call Logoff.
Does it owkr if you only have calls to Logon and Logoff with nothign in
between?
Try to to all CDO handling code into a separate sub:

Set objCDOSession = CreateObject("MAPI.Session")
objCDOSession.Logon...
DoCDOStuff(objCDOSession)
objCDOSession.Logoff

This way all implecit variables (such as thouse created when yo uuse
multiple dot notation) will be released when the DoCDOStuff sub above exits.

Thanks for the reply Dmitry

I tested it by calling Logon and then Logoff immediately following it. It
still hangs.

Here is my test

Sub TestCDO()

Dim objCDOSession As Mapi.Session

Set objCDOSession = CreateObject("MAPI.Session")

objCDOSession.Logon "", "", True, False
'objCDOSession.Logon "", "", True, True
objCDOSession.Logoff

Set objCDOSession = Nothing


End Sub

I also disabled all Add-ins and Com Add-ins and while Outlook loads a while
lot faster, it hasn't alleviated the hang. Is there anything else you can
think of?

TIA

It doesn't appear to. I created a Test profile that connected to an exchange
server but set message delivery to goto a PST and I can close Outlook and
the process doesn't remain in memory. The issue is with Outlook when
connecting to my exchange server it just manifested itself when I was
running the CDO code to the point that I noticed it. I've been
troubleshooting that issue now and I can't figure out what the problem is.
It happens in windows safe mode with network so I know is isn't any external
programs and it happens in Outlook safe mode so I know it isn't any add-ins.
Any ideas for troubleshooting further? When I open Outlook and then close
it, the process stays in memory and spikes the CPU to 60-100% until I kill
the Outlook.exe process manually. Process monitor shows it checking some reg
keys for TCP/IP bindings over and over again with buffer overflows.
