Hi there,I am trying to uninstall Exchange 2007 installed in a single server named "MAIL"and got the following Error:Uninstall cannot continue. Database 'Public Folder Database'. The public folder database "MAIL\Second Storage Group\Public Folder Database" contains folder replicas.....I found that the Events Root in System Public Folders has the following Replication setting:Name : Public Folder DatabaseStorage group :Second Storage GroupServer : MAILI remove the Replication in the Events Root but it keeps coming back after I press the "Apply" button.Any ideas? Thank you!Liu Lin

if this is the last public folder that you have in the org, try running this before doing uninstallremove-publicfolderdatabase <name> -removelastallowed.

You can safely ignore the certain folders in PF's These will be recreated when you create PF databases. Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Hi, If we have other Exchange Server, then we need to remove data from a public folder database, delete any unnecessary public folders, and then move the remaining folder replicas in that database to a public folder database on another server. If it is the last exchange Server in the network, then please try to remove all the public folder instance and then remove public folder database.
