Create Dynamic Distribution List in EXO using Recipient Filters
Hello - I'm brand new to EXO Dynamic Distribution Lists; trying to create a simple (I think) Dynamic Distribution List in that's based on the recipient's SMTP domain, so something like:
New-DynamicDistributionGroup -Name "TESTDDG3" -RecipientFilter "(RecipientType -eq 'MailUser') -and (PrimarySMTPAddress -like 'mydomain.com')"
The syntax is accepted, and the group is created... but doesn't populate with the appropriate MailUsers. Can anyone help with the syntax?
- Afaik PrimarySMTPAddress is not supported for recipient filters. You can use UserPrincipalName instead, which in most cases should match the PrimarySMTPAddress anyway. Another option is to use the Emailaddresses, though you cannot specifically match the primary one with it.
Also, when creating the filter, make sure to add an asterisk and the @ sign:
Get-Recipient -RecipientPreviewFilter {(RecipientType -eq 'MailUser') -and (Emailaddresses -like '*@contoso.com')}

"Set-DynamicDistributionGroup: | Microsoft. Exchange. Management. Tasks. RecipientTaskException | Wildcards cannot be used as the first character. Please revise the filter criteria."
