When you are trying to move a maibox from Exchange 2003 to Exchange 2010 you may get the following error:
Active directory response: 00002098: SecErr: DSID-03150BB9 problem 4003 ( INSUFF_ACCESS_RIGHTS),
The solution is to:
1- Access Active Directory Users and Computer (Windows Server 2008,
since you may not find this option under AD Users and Computer in Win
2003)
2- Select Advanced Features under View menu option
3- Right click under the user account that has presented the issue
4- Select Security, Advanced and tick the box "Include inheritable permissions from this objet´s parent"
5- Now try moving the mailbox
