In Exchange 2007, I have a public folder that I need to take ownership of. How can I do this? I have tried as teh domain admin and it gives a mapt table error.

Hi, What’s the meaning of a mapt table error you mentioned? Could you paste the detail here? If you want to add owner permissions to access public folder, please use the below command for example: Add-PublicFolderClientPermission -Identity "\Marketing\West Coast" -AccessRights Owner -User Kim http://technet.microsoft.com/en-us/library/bb124743(EXCHG.80).aspx More information: http://technet.microsoft.com/en-us/library/bb310789(EXCHG.80).aspx Thanks, Richard.

Thanks for the reply Richard. That error should have read: Add-PublicFolderClientPermission : Failed to modify the MAPI.NET table property of the object "\foldername" on server "servername". See inner exception for more information. At line:1 char:33 + Add-PublicFolderClientPermission <<<< -Identity "Foldername" -Accessrights folderowner -user username I think I have solved my issue using PFDAVADMIN, but I would like to learn how to fix this from the command line. Essentially, all Owners of the folder had been removed and I suspect the above error was due to not haveing permissions on the folder, even though I'm in the public folder admin role group?

Hi, Would you please let me know the below questions? 1. If all the public folders having this issue? 2. If you create a new public folder and add the right to it, will the issue occur? 3. Did you do migrate on this public folder store? Thanks, Richard.

I have the same error trying to modify permissions on a public folder. 1) no, only a few of the public folders have this issue. the issue may affect a parent folder, but not the subfolders in some cases. 2) new public folders do not have any issues. 3) all the folders were originally exported from an old server and imported on a new server.

With pfdavadmin open those folders and under properties of that folder, look at the DACL state. It should be good. If its not, right click the folder and select Fix DACL.
