Hi folks, So, long story short, because of a telephony integration issue we ended up deleting a mailbox and recreating a new one with the same alias. We're on Exchange 2007 - I'm new here and so don't know the full history, but I can only assume the Exchange organization goes back to 2003, 2000, and possibly even 5.5. The original problem was resolved, but now there is one user in particular that gets NDRs OCCASIONALLY when they try to email the individual in question. Two other users have complained of issues one time only. When I created the new mailbox I did not manually add an X500 address using the LegacyExchangeDN...the user who is getting the NDRs has deleted their Outlook NK2 entries, but emails keep coming back with:
IMCEAEX-_O=ACME_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=wilecoy...@acme.corp #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ## Will creating a new X500 address from the LegacyExchangeDN resolve this? It is very intermittent, so I can't really reproduce the issue on demand....
