I have extended schema for exchange 2010. Am currently in exchange 2003 sp2. once i have extended, I have started receiving calls from other exchange admins saying they are not able to open others mailbox without giving the credentials , earlier they were able to do this.

any clue?


Hi Mansoor,

Please run the setup /PrepareAD.

"Don't run this command in a forest in which you don't plan to run setup /PrepareAD. If you do, the forest will be configured incorrectly, and you won't be able to read some attributes on user objects. "
