How to create a large distribution group

Posted on 2008-09-30

I need to create a large distribution group/list for non-exchange email addresses on our exchange server.  I've tried just creating a DL but exchange limits the number of contact within the DL to roughly 100 or so.  I've read in other forums however of users working with DL's listing thousands of entries.  My question is....  how can I get a list greater than roughly 100 names?  Am I using the wrong method to do this (create a DL via Outlook)?  Do I need to create some sort of AD entry instead of a DL?  I'm new to exchange administration to please bear with the ignorance of my questions...  Thanks

Why not use something like mailman or phplist

They are free software

Interesting..  I'll look into it.  Meanwhile, is there no way to do this in Exchange?  I've seen evidence that it's possible, even on the EE site ( but I can't figure out how to do it.....

The link points to instructions for creating a DG in the AD.  Problem wiht that is that I can only add other AD objects to the DG.  I need to add non-AD email addresses (external email addresses) to the list.

explain me: do the contacts exists in your AD? If not you have an issue :)

You could store the contacts in your address list of exchange. Then you are able to create a Query based distribution group where you can add contacts to. This works for me.

The contacts do not exist in the AD.  They are simply outlook contacts created in a public store.  I can create a DL and add them to the DL, but not more than 100 or so.  once you get over about 120 of them you get an error that the DL is too big to store on the server.  This is also true for any DL you create in your contacts folder locally (within the .ost which is synced to Exchange).  But you can easily exceed this limit by creating the DL in a separate .pst file.  But of course, then it's not part of the public store and is only accessible on the client where the .pst file lives.

I've decided to go with multiple DL's.
