Exchange 2003 public folder, send as problem

I'm trying to configure a send as-rights on about 5 public folders for 3 users, but i keep getting the message:
- You do not have permission to send to this recipient. For assistance, contact your system administrator.

The situation is as follows:

- SBS 2003 with Exchange 2003 SP2.
- The primairy domain name is:
- The public folders have also e-mail adresses of other domains:
   - etc.
- The users are owner of the public folders as client rights.
- The users have full control as directory rights.

I tried several notes on this forum and on the article of Neil Hobson*, but what ever i do, it keeps generating erros. I also configured the administrative rights "Send as" on the public folder, i configured "Send on behalf" but even that generated the same error. Also for the public folder with e-mailadres, for which in fact the VS FQDN is right.

What do i overlook?

Regards, Hans

Hi Dan,

Thanks for your answer. I looked into the article but don't understand what you mean; replication isn't mentioned in this article and when i search on for "send as" and "public folder replication", i get no results.

This Exchange is on a SBS without other Exchange servers. There's one other thing that comes to mind: the e-mail domain is: "", the server domain is: "".

Regards, Hans.

Got it. It had to do with 2 things (have to double check to be sure):

- User has to be both owner of the folder at the "Client permissions" form as have to have full rights at the "Directory rights" form.
- When sending, i have to go to the address book, change the view to "Public folders" and manually select the public folder.

I'm not sure weather i can use (security/disctribution)groups or that i have to add every user individually, but this is already a start.
