Thanks, but I can't used pre-canned filters because the CustomAttribute1 criterion needs to include a wildcard. I HAVE to use -RecipientFilter. Followup from my [Edit] last night: Exchange won't let me search on -RecipientTypeDetails -ne $null, nor on -RecipientTypeDetails -ne 'SomeMailboxTypeThatDoesn'tExist', so that's not a solution.

EX2010 SP2 I need to create a custom GAL that includes a wildcard filter for CustomAttribute1. So, something like-- -RecipientFilter {(CustomAttribute1 -like "SomeText*" -and RecipientTypeDetails -eq ?????? )} The '?????' is what I need help with. Being a GAL, it needs to include all recipient types. And to avoid being a maintenance problem, it needs to include not just recipient types in EX2010 SP2, but those in future versions. -IncludedRecipients has an AllRecipients value that accomplishes this. RecipientTypeDetails doesn't have a value like AllRecipients, and doesn't accept wildcards. Is there some way to construct a RecipientFilter to include all recipients in a custom GAL that uses wildcards in another property without explicitly specifying -RecipientTypeDetails -eq UserMailbox -or -RecipientTypeDetails -eq MailUser -or -RecipientTypeDetails -eq ConferenceRoomMailbox -or [...] [Edit] Just hit me: -RecipientTypeDetails -ne $null should work...right? TIA

Hi there, It is best to post this question in Exchagne development forum. Your understanding would be appreciated. Fiona Liao TechNet Community Support

Sounds as though the correct answer to the question I posted is "No", as I had feared: That while one can do many things with a custom filter than canned filters, including returning all mailbox types, now and forever, is not one of them.
