Hi All,

Could you please help?

Every time I sent to Distribution list or recipients I got a”
Delivery has failed to these recipients or groups:
Your message wasn't delivered because the recipient's e-mail provider rejected it.

I know why i am getting this error, because we migrated all users form one domain to the other and we switch off the old domain.

Question is : how do i search or find this user in AD or Exchange 2010 " bec5f1a1-ff3e-4264-86e9-7bb4f6b6233f@domain.com"  
Is any script or GUI i can find the SMTP in Exchange 2010 and Exchange 2003

Thank you in Advance and your Quick response

Those addresses may be reffering to objects from your old domain which no longer exist. So you won't be able to search for them since they aren't there.

Try to type in the whole address manually rather than picking from the address book or using the address shortcuts that pop up when you start typing.

Yes, they are referring to old address, if I log on to exchange 2003 which old domain, am I able to type that SMTP in AD and find the user account.

Where do I type the whole address manually. In the un deliverable email I only get this address.  
Which is does not tell me full name.  

Note: getting hard to identify the user name when you sent it to distribution list. That where I am getting un delivery email.

It sounds like you need to rebuild your distribution lists with the new addresses, then.

Instead of the "old users" does it work with a new user who was never in the old domain?

Hi again Rabihhaj

As I said originally, you are getting that error because Exchange is looking for that SID (security identifier) and it no longer exists. So there is probably nothing you can search on because it is gone.

Having said that, there are some scripts that might help you out. Rather than repeat what they say, here are the links:



The second link also mentions a tool, but I've never tried it.
