The DMA is trying to resolve links to another AD User Object that is in the "ExchangeSecurityDescriptor" and "GrantSendOnBeahlf" attributes. When the DMA searches AD for the GUID listed the AD Object cannot be found so the error is displayed.
When searching AD for the GUID using ADSI Edit the AD Object cannot be found. Upon looking at the user properties for the user id 2D7BA81981BEEE429058D4B84D215796 and examining the attributes from above you can see that the accounts referenced are disabled.
To find the user account for the user ID search the DMA log for the value, in this case 2D7BA81981BEEE429058D4B84D215796.
**Please note that this can be true for any attribute that references other AD User Objects.
