samba - Nov 2003 - Outlook + attached files

I am not sure where to begin to look into how to solve this problem. 

I've setup a samba 3.0.0 Fileserver moved all of my users files over to it,
works great thanks developers=). I've encountered a few documented problems
such as the Excel saving over another file thing(already been patched I
belive). And a few I can't find anything on. 

One specifically is causing me some grief. We use exchange in our
organization, outlook is the email client. If a user attaches a file and
that email sits around for a while, say they attach the file first then
write a 10 page email, it some how causes outlook to go berserk and won't
let you do anything with the email (send, save, delete). If they attach the
files and send it right away it works fine, its only if the file has been
attached for a while. I've found that when it goes berserk I need only
remove the attachment and reattach the file to get it back to normal
functionality. I've glanced over the section on Oplocks and I'm not sure
if
I'm looking in the right direction. The files being attached are from the
home shares in which case the user is the only one with access to the file.
We do use an active virus scanner that has not caused any issues in the past
but just something of mention. I'm not sure if I should continue to look
into oplocks or am I even thinking in the right direction? Below is my
smb.conf.

Thanks
Chris

hi, sounds mor like a problem of outlook which version do you use, have you
looked
at technet if ms knows your failure,
do a test with a file stored on a networked windows client,
if you have same failure here its outlook

Problem only started occuring when their files got moved onto the new samba
fileserver and its not just effecting one user but all that are on the new
server. People still on old windows fileserver are uneffected.

The problem is just with an attached file from the samba server. If the
email with the attached file is left open for a period of time( I havn't
been able to determin exactly how long) It causes the outlook message to
behave abnormally in the sense that if you try to save a draft message, send
the message or delete the message It produces an error that says something
along the lines of Outlook has performed an illegal operation. But its not
the usual illegal opperation error, just a small box with an ok that you can
click ok and go back to the message. It will continue to do this until you
remove the attachment and reattach it. It only occures with files served
from the Samba server, which is why I'm askin what to look at to try to
resolve the problem. Log files for the users computer all are normal,
nothing out of the ordinary. I've read through the section on Oplocks and am
still grasping how they work, Do you think they could be at all related?
Would shutting off Oplocks potentially help or would it cause more problems.
Am I even barking up the right tree? Since its related to period of time a
user leaves the message with attachment open is there anyway I can try to
log this, if so what would I look for in the logs?

Thanks
Chris

What exactly is the difference in behaviour in between the
Samba served outlook and the Windows served one. I'm trying
to understand the problem here.
