So changing the LegacyDN was the issue? &nbsp;Did I make the right move by just changing it back to what it was before the issue started? &nbsp; Just want to make sure that was ok to do.<br />
Thanks so much

We're running exch 2007...Last night I changed the legacyexchangeDN (CN field) for JOE because it was showing a previous employees name (BILL). &nbsp;I sent a test to the email after the change to make sure it went through and it came back as undeliverable. &nbsp;I went into exchange management, and saw there was 2 X400 address for this person, one was JOEs, and the other BILLs. &nbsp;Since BILLs email address was in the decsription of the underliverable, I delete BILLs X400, leaving the only JOEs. &nbsp;It worked fine for a few hours, and then internal people email JOE were getting undeliverables. &nbsp;I went back into the legacyexchangeDN and changed it back to how it was before the issue and its working again, all emails are coming through fine. &nbsp;The only change that remains is BILLs deleted X400 under JOEs accout (Again, JOEs X400 is still there)<br />
Even though the email is working again, will the deleted second X400 create issues for me?
