Thanks You mean to say permission from his Mailbox? (Outlook Inbox)Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah

I want to add the default and the anonymous back to the inbox folder. I have also give my a full access permission on the users mailbox

What about the Mailbox, did you check the permission on Mailbox? What its showing in Mailbox? Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah

Do you mean check the mailbox permissions with exfolders? If yes, there comes the first error message: Exception: Object reference not set to an instance of an object thanks

First thing is, why are you using ExFolders for one Mailbox? There is no need to user it. Second is, Check i EMC---Recipient Configuration...Mailbox and Manage Permission, Post the permissions you have.Gulab | MCTS-MCITP Messaging: 2010 | MCTS-MCITP Messaging: 2007 | MCC 2011 | Skype: Gulab.Mallah

Hello! I use exfolders for one user because I must add the anonyoumus and default users, and this are MAPI Rights. At Full Access Permissions, there are no MAPI Rights in.

Hi Stephan, Sure, I also could not add it again through Exfolder. But, through my test as below: 1. remove the default and anonymous from the inbox folder, the default seems could not be removed 2. use exfolder remove the anonymous and add it again, there would be an error 3. refresh the mailbox, and check the permission on the inbox floder, I found out that the anonymous showed again automatically Regards!
