I have a test box in our lab that mimics our production Exchange 2007 SP1 environment almost exactly, to the point that both are receiving the same errors when attempting to update an OAB or mail enable a public folder.Both are Hosted Exchange environments housing at least 2 domains each. For the sake of privacy I'll post the errors from my test box.First, when attempting to update any OAB I get the following error: --------------------------------------------------------Microsoft Exchange Error--------------------------------------------------------Action 'Update' could not be performed on object 'Cherry OAB'.Cherry OABFailedError:Failed to generate the content of the offline address book '\Cherry OAB'. Two possible reasons for the failure are that the System Attendant Service is not running or you do not have permission to perform this operation. Error message : 'There is no such object on the server. (Exception from HRESULT: 0x80072030)'.There is no such object on the server. (Exception from HRESULT: 0x80072030)--------------------------------------------------------OK--------------------------------------------------------Then when I attempt to make changes to a mail enabled public folder I run into an error, which I believe to be related. So when I try to "Update Content" on a mail enabled PF I get the following: --------------------------------------------------------Microsoft Exchange Error--------------------------------------------------------Action 'Update Content' could not be performed on object 'SPAM'.SPAMFailedError:Cannot start content replication against public folder '\WZOK\SPAM' on public folder database 'ORANGE\Second Storage Group\Public Folder Database'.MapiExceptionNoReplicaAvailable: StartContentReplication failed.

I still belive it to be a permission issue, but I feel as though I've tried everything possible without breaking the entire aspect of what "Shared Hosting" means.Does anyone else run a setup like this and have they run into this issue? Or does anyone at all have any clue why this could be happening?

Dear customer: Did you start system attendant service? If not, please try to start it and check the effect. Please let me know the complete command that you have run, then run the following command and post the result into the forum: Get-offlineaddressbook | fl Check the user that you logged on is belong to Exchange Organization Administrator role, if not, please add it into Exchange Organization Administrator role and check the effect. For your second issue, I suggest that you post the issue into a new thread. Thanks for your cooperation. Rock Wang MSFT
