Event ID 21071 occurs in Office Communications Server 2007 R2

Symptoms

You have a computer that is running Microsoft Office Communications Server 2007 R2. The following event is logged in the Office Communications Server log:This issue occurs if you have two or more values in the proxyAddresses attribute that are identical, except for differences in accents. For example, the attribute has the values helene@vdomain.com and
hélène@vdomain.com.

Note This issue only affects Microsoft Office Communicator Mobile 2007 R2 users.

Cause

In a Microsoft SQL Server database, index comparisons are made by using the Latin1_General_CI_AI collation. Because the rules for this collation are case-insensitive and accent-insensitive, values that contain accented characters will be indexed without these accents. For example, the value hélène@vdomain.com will be indexed as helene@vdomain.com. However, when the attribute also has the value helene@vdomain.com, this value will also be indexed as helene@vdomain.com. Because of these duplicate indexes, SQL Server throws an exception.

Resolution

To fix this problem, apply the following update:
