Comparison Operators
Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The Exchange Management Shell has a rich set of operators that enables comparisons of one object with another object or one object with a set of objects.
For more information about comparison operators, run the following command in the Exchange Management Shell:
Get-Help About_Comparison_Operators
Table 1 lists the comparison operators that are available in the Exchange Management Shell. Some comparison operators are case-sensitive. Other comparison operators are not case-sensitive. If a comparison operator is case-sensitive, the case that is used in the strings that are being compared must match. For example, the string "Test" does not match "test" when you use a comparison operator that is case-sensitive.
