GAL Issue?

I have a user that was accidentally deleted from Exchange/AD a few weeks ago.  I recreated her account from scratch instead of restoring it.  Some of our users are having problems sending to her now.  See the following error message.   Knee jerk reaction is users are using cached mode and for whatever reason their GAL isn’t updating, but not sure.  I believe it works for me because I've for a manual GAL Update.  I did a manual force on another user but the problem persisted.  I use Outlook 2010 and they use 2007.  Shouldn't make a difference, but it's another variable.

The user has a new legacyExchangeDN value
You need to create an X500 email address for the new user account using the old legacyExchangeDN value for the address
X500:/o=Mail/ou=Exchange Administrative Group FYDIBOHF23SPDLT/cn=Recipients/cn=alias

belongs to old email account that was created previously for the user. The only way to resolve this out is to either delete this email address from the senders outlook using delete button while the name pops out automatically from the outlook cache in the to field.

Other way around is to delete the *.nk2 file from the users system that stores the email addresses cache.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

you can add it thru the GUI, just select Custom under the add button in the email address tab for the mailbox

or you can use the shell
$user = get-mailbox alias
$user.emailaddresses += "X500:/o=Mail...
set-mailbox $user -emailaddresses $user.emailaddresses

it would be best to add the address simply because replies to old messages will also result in an NDR

don't use adsiedit, use the exchange management console, recipient management, mailboxes
properties for the new mailbox
email addresses tab

We have faced the similar issue in our Migration. We started migrating users from Exchange 2003 System from one Organization to another Organization comprising of Exchange 2007 and most of the users started facing similar issue with x500 connector.

This will be the simple solution of deleting the *.nk2 file from the users system. Also bear in mind, when the same user will try to reply to the old email that was sent by the email account that was created previously, we have to reselect the same user from GAL.

the X500 address resolves this issue, you could have done the same with your migration and saved a lot work removing nk2 files :)

that's what i'm trying to avoid.  we have too many users to delete the nk2 files from cache not comfortable writing a script to do so.  trust me, risk tolerance is low.  how can i tie the old id into the new one or is it even possible?  the new account is exactly like the old with the exception of the SID and mbox id of course.
