Data

• Identity: User1, CustomAttribute1: aa
• Identity: User2, CustomAttribute1: aa bb
• Identity: User3, CustomAttribute1: aa bb cc
• Identity: User4, CustomAttribute1: bb cc
• Identity: User5, CustomAttribute1: cc

Above is the data available in my domain. I would like to create a Dynamic Distribution Group to select the users with the CustomAttribute1 contain bb.

I created below Dynamic Distribution Group but no result returned.

New-DynamicDistributionGroup -Name "bb" -RecipientFilter (CustomAttribute1 -like 'bb')

Please help.

Thanks.

You need to surround the b's with wildcards 

New-DynamicDistributionGroup -Name "bb" -RecipientFilter (CustomAttribute1 -like '*bb*')

Tried before and it show me error as below.

Wildcards cannot be used as the first character. Please revise the filter.

After I remove the first wildcard, it also did not show me the expected answer.

Hmm, it should be a perfectly valid filter... Try this

New-DynamicDistributionGroup -Name "bb" -RecipientFilter {(CustomAttribute1 -like '*bb*')}

This is a limitation of using overloaded attributes.  Use separate attributes for separate tags.

Giving me the same error message.

Hi,

What's your Exchange version? I tested with the same configuration in my Exchange 2013 environment. I can create a Dynamic Distribution Group with the following command correctly:

New-DynamicDistributionGroup -Name "bb" -RecipientFilter {CustomAttribute1 -like '*bb*'}

Please make sure the CustomAttribute1 is set correctly for these user. Also check whether User2, User3, User4 can be filtered with the followng command:

Get-Mailbox | Where { $_.CustomAttribute1 -like '*bb*'} 

Regards,
