After upgrading our exchange server 2003<2010 I can no longer access another users inbox when using outlooks (2003) open another users folder "inbox", I get the error message "unable to display the folder, the inbox could not be found" error.
I am a domain admin and have added my acccount to EMC > Recipient Config > Mailbox > Manage Full access prmissions.
I have also ran add-mailboxpermission command to ensure that my account is assosiated with that mailbox.
I have checked the sercurity permissions on the account via ADUC to insure I have full access to the user account there as well.
Does anybody have any idea's?
