Our organization recently underwent a name change and with it a new domain structure. We were supporting the old email addresses for a while but have mandated that the old addresses be retired. Now the old addresses are causing an issue with our mail routing.

How can I on-mass remove the old addresses without going through each AD account individually?

What kind of isse? – joeqwerty Oct 9 '09 at 19:48

If all your addresses were being generated by recipient policy, just change the recipient policy and trigger the RUS to "Rebuild".

This is one of the reasons that I refuse to manually add addresses to individual recipients. If someone needs an "alias" I create group with the appropriate alias / address and put the user into the group. To my mind, all addresses in the Organization should be generated by recipient policy.

While it was generated by recipient policy, the policy was set on the previous domain and the accounts were migrated across to the new domain -- the policy doesn't exist any longer and the addresses are now "legacy". I think the ADModify app will solve the issue. – user22519 Oct 13 '09 at 20:17

Admodify from Microsoft is your friend.
