DTOO262 - Outlook - Run in FIPS compliant mode must be enforced.

Information

Outlook can run in a mode that complies with Federal Information Processing Standards (FIPS), a set of standards published by the National Institute of Standards and Technology (NIST) for use by non-military United States government agencies and by government contractors.
By default, Outlook does not run in FIPS-compliant mode. Organizations that do business with the U.S. government but do not run Outlook in FIPS-compliant mode risk violating the government's rules regarding the handling of sensitive information.

Solution

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2010 -> Security -> Cryptography 'Run in FIPS compliant mode' to 'Enabled'.
