Similarly there are some more mailboxes that i have seen which have SAM acct names and aliases different and which are not listed both in exch 2000 version and 2003 version .
PS: Is it because the accounts that is owning these mailboxes does not own any other ?
~DEL means that custom attribute 10 will be cleared. If the samAccountName (Windows NT Account) and alias match it is assumed that the mailbox is the primary mailbox for the account and attribute 10 will be cleared.
Entries without a value in attribute 10 will be assume to be the primary mailbox for the associated Windows NT Account. "NTDSNoMatch" should be put in attrib 10 for all other mailboxes that have the same Windows NT Account, only one mailbox for each NT Account should have a blank attrib 10, the rest should have NTDSNoMatch. For the non-primary or resource mailboxes, the ones with NTDSNoMatch, a new account will be created for each of them, based on the directory name I believe. This new account will be made the primary account for the mailbox it was created for. In addition, the account that used to have be the primary NT Account will be granted user access to the other mailboxes.
Note: You should be using the ADC Wizard in Exchange 2003 SP2 instead of ntdsatrb utility, if that is what you are using.
From your example data provided below your Exchange directory should be fixed so alias names are unique within your org. Getting the primary NT account and resource mailbox issues addressed is the hardest part in migrating from Exchange 5.5 to Exchange 2003.
I would suggest using the ADC Wizard to set the primary mailbox for each account that is currently associated with multiple mailboxes. Then export the information from the wizard and review it to make sure it is correct. Then import the output file, using Exchange 5.5 Administrator, and rerun the ADC Wizard, after waiting for directory replication to carry out.

I have used the exchange 2003 version NTDSNomatch Utility and have printed the output .Now it has printed all accounts with more than a mailbox with the NTDSNoMatch stamping. Here is the output .where the SAM acct name and the alias is different it has stamped NTDSNoMatch.But it has stamped a ~DEL to the account where the alias and SAM acct name are same .
For eg :
For 1 entry from the output file :
Primary Windows NT Account
What it means by ~DEL stamping ? Does it mean if if i did not use the NTDSNoMatch the user Phyllis Grigsby is not going to access his mailbox ( even though his alias and SAM acct name is same in the first row) once i move th emailboxes to win2003 ?
