Outlook 2007 / 2010 Exchange 2010 Send AS problem

[anthonyaudi]

Hello people, I need some expert advice. I am going to rip my hair out here.

I have mailbox A that needs to have a few people be able to send from it.

I have exchange 2010

I gave the users the Send As permission and the Full Access permission

I also went into ADUC and in the security tab added the users and gave them full access to the user whos mailbox I want them to be able to send from (because for whatever reason from the EMC it would add the user in the security tab in ADUC but not give them any permissions...allow and deny wouldnt be checked off)

Here is the kicker.

When I try to send an email from email1@domain.com from user1@domain.com <--the user who should have access to this mailbox from Outlook it doesn't work

When I try to OWA it works.

I read that the OAB files might need to be updated so I downloaded the Address book from Outlook...nothing...I even deleted the OAB files from the profile...nothing

I went as far as to delete the mail profile completely...nothing...

I am out of ideas I know I am missing something but what....

I cant understand how it works from OWA but not Outlook

Edit: This may or may not mean anything but when I get the bounceback in my mailbox I get this error

You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk.

It is FROM: MICROSOFT OUTLOOK and not FROM: email1@domain.com

EDIT: I found the problem. The problem is related to the address book. The email address that is associated to this particular account is wrong. I tried removing the entire account and readding it but the users always see wrong@domain.com instead of right@domain.com for the email address in their contact list. How do I remove all entries for this in Exchange 2010 I tried everything I can't see any evidence of this email address anywhere anymore but it still seems to be lingering in the Global Contact List.
