Remove CustomAttribute14

Question

Hi

We have the following distribution list set up on our Exchange server

Computing Staff
((((Department -like 'Computing') -or (CustomAttribute14 -like 'Computing'))) -and (-not(Name -like 'SystemMailbox{')) -and (-not(Name -like 'CAS_{')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox')))

I am new to Exchange Powershell.

I would like to remove CustomAttribute14 -like 'Computing')))

What is the correct command and syntax to do this?

Also where is a good place to find resources to learn powershell and exchange powershell?

Many thanks,

Anthony

Hi @Love Doktor ,

It should be a Dynamic Distribution Group right?

So if you want to remove the CustomAttribute14, you should use Set-DynamicDistributionGroup to rewrite the RecipientFilter:

Set-DynamicDistributionGroup -Identity DDG -RecipientFilter "Department -like 'computing'"  

For more information about the RecipientFilter parameter, you could find it on the above document(Set-DynamicDG).
Note if you use Exchange Management Shell(EMS) to set the RecipientFilter or other parameter that the EAC doesn't have, the EAC will not be able to used to modify the Membership settings:
After run:

Before:

And these document would be helpful: Custom filters using the RecipientFilter parameter and Filterable properties for the RecipientFilter parameter on Exchange cmdlets
