Hi all, I have been trying to remove permissions from a user's mailbox in A.D. under Mailbox Rights on the Exchange Advanced tab (windows SBS 2003 standard) but get the message "you cannot remove x because this object is inheriting permissions from its parent." I can't really find where the parent object is. The AD structure is the standard domain.local>MyDomain>Users>SBSUsers, with all users being contained in the SBSUsers folder/OU. Initially I thought this meant that the SBSUsers folder was the parent object but this doesn't seem to be the case as inherited permissions are different. Any help would be appreciated. This is my first post here so please be gentle. If this has been posted in the wrong place or someone else has already answered the question elsewhere, please direct me as required. Cheers, Brad

If you are looking at the security of a user in ADUC, click the advanced button at the bottom. Scroll through until you find the type and name of the user you are trying to remove. Under the "Inherited From" column, it should show you exactly where it is being inherited from. You can override inheritance, but you shouldn't need to unless this is a very special user or security has been messed with farther up the food chain. May I ask what kind of permissions are you trying to remove? J.G.

Thanks for the reply John,When I click on the advanced button (on the exchange advanced tab under mailbox rights) I can add or edit permissions but not remove. The remove button is greyed out. The "everyone" group has full access to all mailboxes and I need to remove this. On a side note, I have inherited this server and I really have no track record of what has happened over the last 2-3 years.I appreciate any further advice or help you can give John.Best wishes,Brad

Hillbr74, I have the EXACT same problem here. Unfortunately it is occuring on Authenticated Users and Anonymous Logon also. I did not setup this server, but now have to deal with it. I have followed the nodes all the way to the Domain level and cannot find the parent node that is responsible for this. I admit to being fairly new to Active Dir and Exchange 2003 but this seems as if it would be as simple as finding the parent and removing the permission set. If I find any answers I'll post back for you. Thanks to any that can assist.

If it is the rights on the Exchange Advanced tab, have you looked in Exchange System Manager for the rights? I would look at the rights on the Mailbox Store that the user is in, and work my way up the chain to the Admin Group and then the Organization.

I know I'm bumping an old topic but I was browsing the net to find a solution to a similar problem...An old domain admin had the read right on every mailbox.Since the right was inherited and I absolutely didn't want to remove the inherited right option, I looked everywhere to find where this inherited right came from.Finally, I found it ! It was in the AD schema itself.Just do : run, adsiedit.msc then browse for OU or CN related to Exchange. In my case, I had to look in the security option of (properties, security tab) :In "Domain NC" OU=Microsoft Exchange Security Groups,DC=mydomain,DC=comIn "Domain NC" CN=Microsoft Exchange System ObjectsIn "Configuration Container" CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=mydomain,DC=comWhen in doubt, I strongly advice you to look the Security tab of each related OU or CN in the schema, that what I've done and 20 mins after, the inherited permission was gone (so let it be some time to see if it worked, it's not instantaneous).I hope this solution will help fellow administrators ;-)

Hi Guys, I have been searching around for weeks on this issue - it seems to be quite a tricky thing to resolve. The exchange box was setup a couple of years before my time and for some reason the person that set it up thought it would be a good idea to give the EVERYONE permission to all mailboxes. I have looked everywhere - but cant for the life of me discover where the everyone permission is being inherited from. Here is some info - In AD - go Exchange advanced tab - Mailbox rights button - in here there is an everyone permission with grayed out read access. If i click the advanced button here it just tells me its inherited from the parent...not very informative. As someone suggested i checked all AD OU's for this permission but its not anywhere in AD - i even used adsiedit.msc but none of the items in there had the permissions either. In exchange system manager - i right click on the lowest point, the 'mailbox store (servername)' and check the security tab - click the advanced button and in here there is an everyone entry with read permissions and a few others that are greyed out. So i go up to the next level - right click on the 'Servername' in exchange system manager - properties - security tab and then the advanced button. the everyone special permissionare also in here but grayed out - i cant go any higher. So my question is - where else can these permissions be inherited from? in the delegate control area of the organization and domain in exchange system manager there are no strange accounts in there just the admin and besadmin account i added for blackberry server. thanks in advance guys

Did anybody find a solution? We are experiencing the same problem. Thanks.

I had this problem and found the setting was hidden in the properties of the mailbox store for the user.In Exchange System Manager, right-click the Mailbox Store that the user belongs to. Go to Properties, Security tab. All the checkboxes might be showing as cleared. However, if you click Advanced, you will find a list of applied permissions for the Store. Some of them will be assigned to the Everyone group. Check each one. In my case, the users were getting the Read permissions from a 'Special' permission in this list. In fact, the permission was duplicated here 3 times. I removed two of them, and on the final one I cleared all the checkboxes.Back in AD Users and Computers, the mailbox right was no longer showing.Try it and let us know if it works.
