We've had this issue for a while, but thought I would give one last try to see if there was something I could do to fix it. Anyhow, we are using Exchange 2007 Sp1 on Windows Server 2003. Desktops are Outlook 2007. The issue we have is that when a user with Author permissions sends an email to a mail enabled public folder, they cannot modify it or delete the message after it goes to the folder. If that same user posts to the folder (via going the public folder rather than selecting it from the address book), they can modify and delete the post as expected. When testing this, I also noticed that if I gave the user Editor permissions, they can now edit and delete their own messages...but the problem is they can do that with other users messages as well, so this won't work. Any idea why Author permissions don't work as expected when sending an email to a public folder? CM

How is the message mailed? It is probably being considered an anonymous post. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .

It's a mail enabled public folder, so usually they just select it from the address book rather than sending it to the email address. Is there a way to tell how it is being posted?

Does the issue happen to all public folders, including newly created ones? Does the issue happen to all users when they have the Author permission on the public folders? Does the issue still appear when attempting to modify users’ own items in the public folder via OWA? What’s the error information? Have the Author permission ever worked before? Have you tried to grant the permission with values, instead of roles in the “AccessRights” parameter of the “Add-PublicFolderClientPermission“?James Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

Yeah, that should work from my experience. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .

Sorry, I was away from the office for a few days. To answer your questions Does the issue happen to all public folders, including newly created ones? - Yes, it doesn't seem to matter whether it is an existing PF or a new one, still can't delete when you email the folder and you have Author permissions Does the issue happen to all users when they have the Author permission on the public folders? - Without doing a massive survey of the user base, I would think so yes. At least in my testing it consistently fails. Does the issue still appear when attempting to modify users’ own items in the public folder via OWA? - Yes, using OWA doesn't make a difference What’s the error information? - In Outlook and OWA it says "Some items cannot be deleted. They were either moved or already deleted, or access denied". Have the Author permission ever worked before? - Yes, as I recall this issue came up only after we migrated to Exchange 2007, previously (EX 2003, EX2000) it worked Have you tried to grant the permission with values, instead of roles in the “AccessRights” parameter of the “Add-PublicFolderClientPermission“? - I tried using the powershell cmd line to set permissions, didn't make a difference. So as of right now, there is no change, author permissions don't seem to work properly if the message is emailed rather than posted.

Based on the error and the symptom, I think it’s a known issue in the exchange 2007 Users cannot delete or modify their own e-mail messages from a mail-enabled public folder in an Exchange Server 2007 environment The KB above has provided two workarounds for the issue, and another one I know, is to use a resource mailbox instead of public folderJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com
