  • Exchange Admin - Full Mailbox access "Deny"

    For some reason in Mailbox Rights my account has a Deny "Full Mailbox access" on every mailbox in the org. I am the Exchange Organization Administrator and can't figure out where the User accounts are Inheriting this permission from.

    Re: Exchange Admin - Full Mailbox access "Deny"

    Just because you are an Exchange administrator it doesn't give you rights to all mailboxes by default. As you have discovered, Domain Admin accounts have an explicit deny.

    I personally believe that an administrator does not need full access to all mailboxes to their job. It is not a permission I have ever asked for, been given or needed.

      Agreed, but I need access to a Shared Mail account.

      Also, Why would another Exchange Org Admin not have a explicit Deny?

        I can't comment on why another account has the access. I can only comment on the default settings.

        If you need access to a specific account then you should be able to add Full Mailbox access to the account. If you cannot do that then something has been changed from the default.

          I don't believe the default deny is on the "Full Mailbox Access" attribute but on the "Send As" and "Receive As" but I could easily be wrong?

            Re: Exchange Admin - Full Mailbox access "Deny"

            Maybe this is a better question. My Account has the Deny and Allow check boxes marked for the "Full Mailbox access" permission under every account in the organization. And I cannot remove my account from the mailbox rights because it says this object is inheriting permission from its parent. I can seem to find where it is inheriting these mailbox rights from?

              Enable that and see if you can view permissions on the Org. It may have been applied there.

              On a side note and I realise you probably know this but, I would also say I completely agree with Sembee here. There are a few cases where full access is required but for compliance and legal reasons the restrictions are there for a reason.

                Check and nothing there regarding my account.

                The reason this is an issue is because we have a few shared mail accounts, and now I do not have access to them because of the deny.

                On a side note....

                Domain Admins, Enterprise Admins, Exchange Org Admins, Administrator and also my user account all have the "Deny" under full mailbox access.

                  Fair enough, like I said I couldn't remember if "full mailbox" was a default deny as well.

                  You are probably inheriting by being a member of a group, rather than looking for your specific account look for the groups you are a member of. Obviously you would be allowing al members of that group should you change it.

                    I'm confused as to why my specific user account is listed in the mailbox rights for every user account in the entire org? I've looked at the parent objects and its not there.

                      What other permissions does your account have?
                      Domain Admin?
                      Enterprise Admin?

                      If you have Domain Admin then you don't need anything else in Exchange, unless someone has fiddled with the permissions.

                      I suspect that you may have permissions at the Exchange org level, which need to be removed.

                      Oh and on the Send As/Receive As, I think someone is thinking of the protected account process, where Exchange removes the Send As permission granted to accounts that are members of Domain Admins etc.

                        Simon, your speculations were correct. I was setup as the Exchange Org Admin role, I have since changed to the Exchange Server Admin role. Considering I am the only Exchange admin in our org is this the best practice?

                          Are you a domain admin as well?
                          If so then your account doesn't need any additional permissions. You have them already.

                            I am the domain admin, I have since removed my user account from any Exchange Admin Roles...

                            But I am still seeing my user account listed in every user account's mailbox rights with a deny full access. When I installed Exchange I did install it from my user account is that where this explicit deny is coming from?

                              The change will not take effect immediately, because of the way that Exchange reads the permissions. It will be at least a couple of hours. However after you restart the server later today following the install of the emergency patch from Microsoft, the permission should be gone.

                              The fact that you used your account to install Exchange shouldn't have been an issue. I usually use the administrator as a rule, but as long as the account has the required permissions - either directly or by being a group member that has the permissions, it will install correctly. It does not add these permissions to the content - but being specifically granted permissions would.
