Last month I upgraded my servers from 2000 to 2010. The route I took for exchange was 2000 -> 2003 -> 2010. Everything went fairly smooth and I have had no real problems until this week. (I have uninstalled the older exchange servers.) I have been trying to clean out some of the remnants that have been left over from the older servers (for whatever reason the uninstall did not remove the information on the new server). I used ASDI edit to remove some old information that was pointing to the old exchange server (First Administration Group I think it was called). After that I upgraded to SP1 and Rollup 1. The Public folder database no longer appears under Organization Configuration, Mailbox. I am not sure if it was there after my deletion or not, so I am unsure if the problem is caused by my deletions or the upgrade. I followed the instructions found here, http://technet.microsoft.com/en-us/library/bb727370%28EXCHG.80,printer%29.aspx . The CN=Public folders was found in CN=Folder Hierarchies. However msExchOwningPFTree is greyed out, so I cannot update it. I have tried to delete it and remake it, same thing. I also get the following events which I am assuming is caused by the Public Folders database not being mounted: Log Name: Application Source: MSExchangeRepl Date: 10/28/2010 11:03:51 AM Event ID: 3154 Task Category: Service Level: Error Keywords: Classic User: N/A Computer: sachdc00001.sunshineacres.local Description: Active Manager failed to mount database Public Folder Database 1678798462 on server sachdc00001.sunshineacres.local.

Is this normal? Now I am assuming I deleted something that I shouldn't have.

Assuming you have Transferred all system folders etc to exchange 2010 server. To find what is missing install a standalone virtual exchange server and compare with ADSIedit to begin with.,,. would be helpful

Hi, Now I suggest you delete the original Public Folder Database on the Exchange 2010, then delete the Folder Hierarchies by using ADSI. Then create a new Public Folder Database on the Exchange 2010, restart Information Service and check this issue. Thanks AllenAllen Song

Tried that, I get the following when I go to the Public Folder Management Console: Cannot complete the operation because there isn't an available public folder database on server And even if I did that how does that help me retrieve my missing information?

Got the new Public folder dbase up and running, now how do I import the information from the old dbase?

got it figured out

I did the same thing and am having the same issue. Can you share what ended up being the solution for you?

^ BUMP ^ seriously, who posts problems like this, exclaims they got it resolved, but does not explain a single thing they did? /sigh
