Hey guys, I have Exch2k7 SP2 running, and going into Exchange Management Console/recipient configuration/mailbox, I find the user I want to remove. Right-click on their name and choose remove. I get the prompt removing the mailbox will remove the windows user object so on and so on. I select yes and then it kicks back the error:Action 'remove' could not be performed on object 'username'.Error: Active directory operation failed onDC.domain.com. You cannot remove the object 'cn=username,OU=companyusers,DC=domain,dc=com' which contains some children. This operation is not allowed on a non-leaf object.Any idea what I am doing wrong?!?!I can disable the mailbox and it goes into the disconnected mailbox container. I have tried this on a couple of different test mailboxes I have.Thanks!Mike

Hi Mike-Are you able to browse to this user with AD Users and Computers? If so, do this:Open ADUCSelect View>Users, Contacts, Groups, and computers as containersBrowse to the user and expand them in the tree at leftWhat do you see under the user?Active Directory, 4th Edition - www.briandesmond.com/ad4/

Thanks for the reply Brian!If IOpen ADUCSelect View>Users, Contacts, Groups, and computers as containersBrowse to the user and expand them in the tree at leftI see the user, expand that out and I see asub-folder with the same name as the user, then 3 subfolders, one looks like a SID, another called SSOProvisioning, and another called SyncState, nothing is contained in any of these folders.Thanks,Mike

Brian,You rock! After looking at this, and the sub-folders listed it got me thinking about our environment and I went and talked to one of our software architects and sure enough we have a software utility that if a user logs on it creates these sub-folders, hence why i cannot delete the account. If i create a new test account and I don't log on with it, the utility doesn't create these sub-folders and I can delete user/mailbox without an issue!Thanks man!!Mike

Hi Mike-You should be able to delete the user with ADUC. It appears that the EMC does not issue a tree delete, hence the error you're getting.Active Directory, 4th Edition - www.briandesmond.com/ad4/
