Is the public folder database mounted? Is the mailbox database mounted? Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

yes sir. Everything is mounted. They started off with Exchange 2007 and recently completed a 2010 transition. What is even more odd is that both user mailboxes are pointing to Public01. However, when the user sends an email to one of the public folders, it shows up in the Public02 database.

Is the mailbox shown in the error message in existence?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi, How is the issue now? Please try to check the homeMdb of your public folder. Why on earth did my email to a public folder go there? http://blogs.technet.com/b/exchange/archive/2004/09/10/228114.aspx Xiu
