Resolution

To resolve this issue, apply the following update:

2598318 Description of the Outlook 2010 hotfix package (Outlook-x-none.msp): April 24, 2012

Note For this fix to work, the Exchange administrator must adjust a server-side time-out policy. The server-side throttling policy causes a random failure because the expansion takes too much time to access Active Directory Domain Services (AD DS). To avoid this failure, the administrator must increase the RCAPercentTimeInAD parameter to a larger value by using the Set-ThrottlingPolicy cmdlet.

For more information about this cmdlet, go to the following Microsoft website:
