Dynamic Distribution Group including shared mailboxes

I just created a new dynamic distribution group for one of our regions, and it seems to be including shared mailboxes.

New-DynamicDistributionGroup -Name "DYN-ParisRegion" -RecipientFilter "(Office -eq 'Paris') -and (Company -eq 'Contoso') -and (RecipientType -eq 'UserMailbox')"

Is there something I'm missing here? Should it not match to shared mailboxes? I've confirmed in Exchange Online that the mailboxes are listed as SharedMailbox.

    Your last clause is causing the inclusion of shared mailboxes. RecipientType is different from RecipientTypeDetails, and both user and shared mailboxes have the same value from the former. You can however use the latter to single out User mailboxes:

    New-DynamicDistributionGroup -Name "DYN-ParisRegion" -RecipientFilter "(Office -eq 'Paris') -and (Company -eq 'Contoso') -and (RecipientTypeDetails -eq 'UserMailbox')"
