Outlook shuts down when attaching a file

A friend has a problem with Outlook (not Outlook Express) when attaching a file to send with the email. It shuts down and the current email is lost. Apparently the same thing happens when he opens atached files.
What could be the cause? and the solution?

you could try and run the 'Detect and Repair' option from the help menu in Outlook to see if it is a problem with the install. Also, if it happening when he prints a word file, it could be an issue with the printer driver, so a reinstall of the printer driver should rectify this.

if it is a problem with MS Word documents only, then you could do a search on the pc for the Normal.dot template (make sure you include hidden files and subfolders in the search). It is not uncommon for the Normal.dot template to become corrupted. When you locate the Normal.dot template, simply delete it - make sure that outlook and MS word are closed before deleting it. The next time Word opens up it should automatically create a new Normal.dot template.

if all else fails, then just do a full uninstall and then reinstall of Microsoft Office and this should definitely resolve the issue.
That's more than likely caused by Microsoft's 908531 update (Vulnerability in Windows Explorer Could Allow Remote Code Execution); uninstall or try the workaround here:
Problems in Windows Explorer or the Windows shell after you install security update MS06-015
Greetings, keithbraithwaite !

1. Check if Outlook is blocking the attachment.  You need to add the attachment extension in registry key Level1Remove

2. This error could be caused by a recent update to Internet Explorer, MS06-015, as stated by kgreeneit. But here are easier fixes:  

a. If you have Windows XP, copy the following to the clipboard (it's all one line even if wrapped in your browser - paste into notepad and remove line breaks if necessary, and copy again)
click START > RUN and copy the line below into the Run box. Hit <Enter>

=copy below here=
REG ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Cached" /v "{A4DF5659-0801-4A60-9607-1C48695EFDA9} {000214E6-0000-0000-C000-000000000046} 0x401" /t REG_DWORD /d 1
=copy above here=

b. There is an updated version released April 25 to fix the error.  Uninstall 908531 from Add/Remove Programs in Control Panel, and go to Windows Update to download MS06-15 anew.

Best wishes!

I've sent him the line to copy into the "run" box.
However, looking at the list of file extensions blocked by the update, I don't see the sort of extensions he's using: .doc and .pdf
We'll see if the paste works
Keith, any update?

He's copied in the line - he'll let me know if the problem is resolved. He was away all weekend and I only just got my broadband connection back after a break lest evening...

Sorry to say that nothing has changed. Outlook still cuts out when he prints an attached file in Word.

An addin or third party program is interfering with Outlook or Outlook itself has a corrupt file.

1. Reset the Outlook toolbar template. With Outlook close, do a search for and rename outcmd.dat file. Restart Outlook and a fresh outcmd.dat file will be recreated.

2. Register an important Outlook file. Go to Start > Run and type regsvr32 OLE32.DLL
Do the same for INETCOMM.DLL

3. Disable Outlook Addins.  Go to Tools > Options > Other > Advanced Options > Addin Manager or COMM/Addins and disable the addins.

4. Start Outlook in Safe Mode.  Go to Start > Run and type

"c:\Program Files\Microsoft Office\Office\Outlook.exe" /safe

Your path to Outlook.exe may be a little different.

5. Create a new Outlook profile.

6. Repair Outlook. With Outlook open, go to Help > Detect and Repair.

7. If no joy, reinstall Outlook.  Go to Add/Remove Programs and highlight Microsoft Office. Click on Install/Uninstall.  A menu will pop allowing you to choose repair or reinstall.

You're quite right to have closed the question. My apologies. I have been overworked for the past couple of months. Haven't had time to breathe.
My apologies to the people who sent in their suggestions - I've noted them and will try them whan I get time
