Using -like operator to select recipients for Dynamic Distribution Group

Dear Scriptor,

I got few thousand of data and would like to select recipient according to the CustomAttribute1.

Below is the sample data in my database.

1. Name: User1, CustomAttribute1: aa, bb, cc
2. Name: User2, CustomAttribute1: aa, bb
3. Name: User3, CustomAttribute1: bb, cc, dd

If I run the script as below,

• New-DynamicDistributionGroup -name "myDyna.bb" -RecipientFilter {(CustomAttribute1 -like 'aa*')}
• The return result is User1 and User2

When I run the script as below,

• New-DynamicDistributionGroup -name "myDyna.bb" -RecipientFilter {(CustomAttribute1 -like 'bb*')}
• No result returned

How can I overcome this issue?

Thanks.
