We're having some annoying problems after an Exchange crash. Short story - SAN disks died, making drives on the Exchange Server unavailable and we lost log files. Called PSS and ran eseutil /p and eseutil /d and isinteg. That caused a problem withsome BlackBerrys on the InfoStores was ran the utils against - BES was saying "unable to open mailbox". Finger pointing back and forth MS and RIM... so we ended up backing up, nuking and recreating the mailboxes of the afflicted BlackBerry users and re-adding them to BES. Now, we're seeing issues with the 20 or so recreated mailboxes -a meeting is cancelled but doesn't get removed from the Calendar of the recreated person.People get "The e-mail account does not exist at the organization this message was sent to" back when sending e-mail to a recreated person - however if you pick the person from the GAL it's fine. My questions are : Is there any way to re-link the entries in the Calendar back to the person that created them - even though they don't really exist any more ? 2. Is there some sort of cache in the local Outlook ? Can that be purgedfor everyone in our organization to use the "new" mailbox ? Has anyone else gone thru this ?

Sorry. We're running Exchange 2003 SP2 and Outlook 2003/XP.

If you have the original legacyExchangeDN values for the old mailboxes, you might be able to do this by adding an additional X500 address. For example, if the original legacyExchange DN value was /o=YourOrg/ou=YourAdminGroup/cn=Recipients/cn=UserXYZZY, then you would go to that person's new account and add that name as a custom e-mail address of type X500. That *might* fix this since Exchange identifies a lot of stuff with this address. Are you seeing any errors that might include this name? Short of looking at an old copy of your Active Directory or sending a message to a user in the your NK2 file that uses the old distinguished name of the mailbox, I'm not sure how to find this if you have already deleted the mailboxes and created them.

Thanks Jim. I delved into my old PST from last year and grabbed the value for one of our afflicted users and added that as an X500 address (New, Custom Address). Nothing really changed. One thing I did notice - you open the meeting and all Attendees, including the new mailbox person, have the No Information (the white bar with slashes). Even people who's mailbox we didn't touch are no information. Isn't that odd ?
