User is repeatedly asked for username and password in CRM Client for Outlook

Sometimes when working in the CRM Client for Outlook and if Internet Explorer 7 is installed a dialog box appears asking the user to login. Even if the user enters a correct username and password the dialog box reappears. Clicking cancel on the dialog box each time eventually sorts the situation.

To prevent the dialog box appearing change the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_SUBDOWNLOAD_LOCKDOWN

from 1 to 0.
