Problems migrating user mailboxes from Exchange 2000 to Exchange 2007

Hi,

 I was wondering if anyone has every encountered this problem. I'm happily migrating user mailboxes from powershell from Exchange 2000 to Exhang 2007 when errors occured for some users. It comes back with the error: "The administrative limit for this request was exceeded". After the whole day researching on this error, it seems to be related more towards the user object within Active Directory. (We still have a co-existance of Windows 2000 DC and Windows 2003 DC in our environment).

I get the same error when I try to change anything on the user attributes for that particular user. And its the same thing happens when I do this in ADSIedit. Its perfectly fine for other users but just not for this one. I'm very tempted to delete the user and recreate it but I was wondering if anyone has faced this problem before and has a resolution.

DCdiag and Netdiag on all DCs are fine with no errors and there is no errors recorded within the Event Viewer either concerning this.

Any help would be greatly appreciated.

 Thanks.
