I would like a bit of feedback on the following article: http://technet.microsoft.com/en-us/library/ff459252.aspx " Mailbox Full Access Permission and Outlook Automapping In Microsoft Office Outlook 2010 and Outlook 2007, Autodiscover automatically maps to any mailbox for which a user has full access permissions. After an administrator grants full access permission for a user to access another user's mailbox or if the user has full access permission to a shared mailbox, Autodiscover automatically loads all mailboxes for which the user has full access permissions. This behavior may cause performance issues when Outlook starts if the user has a large number of mailboxes to which they have full access. For example, in some organizations, Exchange administrators have full access to all users' mailboxes in their organization. If that is the case, Outlook attempts to open all mailboxes in the organization." This seems like it could cause an admin with full mailbox access rights to have a huge problem? How is this a feature? How does one disable it? Thanks.

I dont think there is a way to disable it. Why would an admin need full access rights to all the mailboxes? I can see special service accounts that may need this, but an admin account doesnt ever really need that - only on a mailbox by mailbox basis for troubleshooting perhaps.

Hi, Administrator will not be grant Full access rights to all the mailbox by default. In the link you provided, it is clearly said "users can’t control or disable this behavior."

I don't have full access to all my 15000 mailboxes but I do have access to about 150 or so. My fault for not removing my permissions after troubleshoooting the account. I guess I will try to find/write a script to find them and remove my full access.
