I am getting this when i try to open a mailbox I have added to my outlook account.

I have set all permissions to full for myself.
I can not even logon as the actual user and open the email box; I get the same error.
I have even tried to move it to another mailbox store but, i cannot do that either.

It is like all the permissions on the mailbox are gone.  However, when i look at them it says i have full rights.

    Have you tried recreating this mailbox since you are not even able to open the e-mail account separtely anyways?  Also if you added this mailbox to an existing e-mail and you are able to access the e-mail separtely then try to send a test e-mail to that address then try to open it.

    What is the update on this?  Were you able to open your mailbox after sending the test mail.  I only say this because I had the same thing when creating the mailbox.  I had to send something to it first before it started working functionally.
