OK, I have had some interaction with MS Tech...they suggested this (as typed by the tech)
Based on the information above, I am afraid we cannot decide what the root cause of the problem is. Therefore, let us follow the steps below to create a new profile, and then test the issue in the new profile.
Note: A new profile is a new environment for us to use Outlook. To create a new profile is only for a test to see if the problem is related to the corrupt profile of Outlook. Creating new profile will not do any damage to the old profile.
Create a new profil
===============
1. On the Start menu, click Control Panel.
2. Click Switch to Classic View, and then click the Mail ico
3. In the Mail Setup dialog box, click the Show Profiles button.
4. On the "General" tab, click to select the "Prompt for a profile to be used" check box.
Note: this step is important for the further steps. Please confirm it
5. Click Add.
6. In the Profile Name box, type a descriptive (I used my last name) name for the new profile, and then click OK.
7. In the E-mail Accounts dialog box, click Add a new e-mail account, and then click Next.
8. Configure the email account in the new profile following the Wizard
9. Click OK
10. Open Outlook and select the new profile you just create
Note: all the folders should be empty in the new profile
11. Send a test email with a large attachment, and try to download it.
Please let me know whether or not the problem still occurs in the newly created profile
