Responces to old mail and meetings fail with NDR

[isguyatlanta]

We have migrated from 5.5 to 2k and several people have reported that when the reply to an old message or try to update a recurring meeting they receive NDR's.

They get this for each user:
The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.

No errors in the logs.

The X.500 address in the original message is no longer in the ORG. You can add this to each user and it will resolve the issue. You will see the address in the NDR. Dan

Any idea why the x.500 address was not preserved?

No idea. Did you see what the NDR refrences? Dan
