After transitioning a user from an old Exchange 2000 to Exchange 2010, some people using the auto complete in their outlook are selecting this persons name and getting a :
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##
Now, prior to this I went in to the Attribute Editor on our new AD environment and added the following as an X500:
Yet, some people are still getting bouncebacks. Funnily enough, I'm on the same Exchange environment and I'm not getting any bounce backs.
However, what I was going to ask was whether I could somehow find the old Legacy Exchange details and add it as an X500? If I go to the attribute editor for this WilliamsA person, I can see that there's a 'LegacyExchangeDN' value. Should I copy and then insert this as an X500 address?
