We are trying to remove exchange 2007 from our network after migrating to Exchange 2010. I thought I copied all of the public folders to 2010, but when I try to uninstall I get an error:
Uninstall cannot continue. Database 'Public Folder Database': The public folder database "EXCHANGE\Second Storage Group\Public Folder Database" is the default public folder database foer the following mailbox database(s): EXCHANGE\First Storage Group\Mailbox Database
Mailbox Databae 1621939451
Before Deleting the public folder database, assign a new public folder database to the mailbox database(s)
I am assuming I need to remove the reference to the 2007 database, just not sure how to remove.
