I have a mixed environment of Lotus Notes and Microsoft Exchange. All notes users exist in the AD as 'Mail Contacts' to facilitate sending of e-mail between systems. When I make a dynamic distribution group to include all recipients, the 'Mail Contacts' get skipped. I even tried making a custom query where RecipientType -eq 'MailContact' and it still ignores the users. Is there any way to accomplish this?

Do you see the contacts when you run Get-MailContact? You might try deleting one of them and recreating it manually to see if they're misconfigured.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi John, Could you please use "get-dynamicdistributiongroup | fl" to get some information about the DDG, and post here, we could do more research regarding to the issue. In my opinion, if you confirm the mailcontact configured properly, please confirm the recipeint configured properly again, it maybe contains some conflict in the recipientfilter. Regards!

get-mailcontact Does produce the list I expect.

Hi John, Per the information, the recipientfilter seems just filter the acount's attribute "office". Please custom the recipientfilter to contain the mailcontact. Or you could create a new OU, and move all the mailcact in to the OU, then recipientfilter the mailcontact base the OU. Regards! Gavin

My goal was to get all recipients with the value of 'Centerpoint' in the office field. I can look at changing that this morning.

Office not a property of the MailContact object, as you can see from the output you provided.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi John, Any update for your issue? You could chose other atribute to filter the mailcontact. Regards!

We resolved this by nesting the dynamic group in a standard group and putting the contact records in as addtional members of the top group. This also allowed us to turn on moderation and made the management of that top group easier.
