What exactly are you asking for? How do you choose which public folders you are going to change? Regards, Michael B. Smith MCITP:EM/MCSE/Exchange MVP http://TheEssentialExchange.com From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Frank Sent: Tuesday, June 17, 2008 10:51 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Public Folder primary SMTP addresses I need to change the Primary SMTP addresses of a large number (but not all) of our public folders from "@exchange.domain.com" to "@domain.com". A lot of these folders email addresses do not have a match between the user part of the email address and the "MailNickName", so ADMODIFY is not a clear option. I've been trying CSVDE and LDIFDE as well as PowerShell. Still...no luck...well...no GOOD luck. Any suggestions would be greatly appreciated. Frank
