Using Exchange 2010 SP1 and 2008 R2 and Outlook 2010 (migrated from exchange 2007 SP2)
Unable to remove these delegated mailboxes even after removing the "FullAccess" permissions
these still appear in outlook
Problem only appeared after upgrading to Exchange 2010 SP1
Tried all possible ways to remove additional mailboxes all fruitless
i have noticed when editing schema
there are no values in this attribute for user
msExchDelegateListLink
and there are multiple values for following attribute
msExchDelegateListBL
and I tried to delete these values but I receive following message
"The attribute cannot be modified because it is owned by the system."
these entries look like
msExchDelegateListBL: CN=Jennifer Eder,OU=Reservation,OU=Al-Qouz,OU=Planet,DC=darling,DC=local
msExchDelegateListBL: CN=Hani Khamis Hamad,OU=Head Office,OU=Planet,DC=darling,DC=local
msExchDelegateListBL: CN=Zhou Yun,OU=Chinese Inbound,OU=Head Office,OU=Planet,DC=darling,DC=local
msExchDelegateListBL: CN=Payroll Head Office,OU=Human Resources,OU=Head Office,OU=Planet,DC=darling,DC=local
msExchDelegateListBL: CN=Jay Kumar,OU=Head Office,OU=Planet,DC=darling,DC=local
msExchDelegateListBL: CN=sumith,OU=2010-Remove,DC=darling,DC=local
