Outlook 2010, NTDLL.DLL, & Exchange 2003

We're an Exchange 2003 (in a 2008 R2 schema AD forest) shop. We have Exchange running on a single cluster composed of two nodes.

We have random instances where there are users who, when using Outlook 2010 to connect to their mailbox, Outlook crashes as soon as it completes loading. This occurs regardless of:

Office location/proximity to the cluster
With or without Cached Exchange Mode
With Outlook 2010 in regular or safe mode
Regardless of Outlook Authentication or Encryption Setting
From any system in our organization - built from scratch or from a corporate deployment
With out any other connections in the profile (ie, IMAP to another server, or a MAPI Livemeeting plugin)

However, with Outlook 2007, there are no issues at all, and the user can work without issue.

I haven't seen any authentication issues for that user logged in our exchange server, and the error logged in the local application event log is as follows:

We're at the point where we're about to export the users' mailbox to a PST file, delete the mailbox, and re-create it. However, I don't see this as a feasible option for tens, or hundreds of users (we're just beginning to push out Win7 and Outlook 2010).

Additional point of data:

We use McAfee VirusScan Enterprise 8.7, Patch 3, in our environment - I haven't seen anything to indicate this is a McAfee issue, especially as we have disabled all plug-ins via Outlook safe mode.
I am not sure if this is a fix - but check this

Points to corrupt helvetica font as a problem
try this after eliminating the usual suspects
Disable antivirus
remove addins
start outlook in safe mode
start > run > outlook /safe

There are multiple instances of this

That's definitely good info (and thank you!) - unfortunately, not the culprit. It follows the user to any machine in the organization running 2010, but any other user can log into the same machine and access their Exchange mailbox via Outlook 2010 without issue.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

It follows the user to any machine in the organization running 2010
>> Corrupted mail item ?
Anything with weird fonts / large attachments / funny attachments / ActiveX in message ?

If you can track down the message and delete it - lets see if that works.

What happens when you do outlook /safe

We've moved the mailbox between message stores, and haven't encountered any corrupted items. She's archived the majority of her e-mail to a PST file, and doesn't have any strange fonts set as a default.

As mentioned above, outlook in safe mode yields the same results.
Will post back if i figure out something.
Can you get the bucket ID of the faulting application

Download and run this from the workstation where her outlook is crashing.

I'll have to get back to you on the ShellExView results - it's being flagged as a trojan. Once I verify everything's safe I'll proceed. Thanks :)
This is from Nirsoft.
Some of the best utilities after SystInternals - which was acquired by Microsoft.

Here's the Faultbucket info - Sorry for the delay (life happened):

Fault bucket 1058594327, type 5
Event Name: FaultTolerantHeap
Response: Not available
Cab Id: 0

Problem signature:
P2: 14.0.4760.1000
P4: ffffbaad

Also, to add - I moved all of her messages around into different folders, as in the past this has always revealed any corrupted messages. I didn't come across any.
Did you try creating a new ad username and then configuring outlook using that ?

I will check the fault bucket and post back

That is the next step - but we've already got many other users with Outlook 2010 working on our exchange system. So we already know that this is specific to this user and that combination. The overall concern here is that we don't know why this is happening, and as such, as we continue to roll out Outlook 2010, deleting and re-creating users would become onerous.
synovatechAuthor Commented:
We've only been able to replicate this issue with the one user - and we reached the point where Outlook 2010 had to work. As such, her mailbox was deleted and re-created. This resolved the issue - even after importing all of her mail back in, the issue did not occur.

As much as I would like to leave this request open in case it occurs again, it is not repeatable at this time. As such, we're going with deleting and re-creating as the answer.
