  • Hi,

    I see a similar problem when user1 sends a mail to user2 and caches the name of user2 in Outlooks cache file. If user2 then for some reason is recretade with a new mailbox the user2 legacyexchangedn will be new and cause problems next time user1 tries to mail the user.

    Try to have the user make sure that he selects his recipients from the address book instead of the cache just to make sure.

    You can correct this problem either by deleting user1's cache or by adding a new legacyexchangedn address as a X500 address to the users he has problems sending to. You can deciffer the address from the above with a little help from a working legacyexchangedn.

  • Hi Leif

    This helped me with this issue. I was wondering though - in the link you provided it shows how to use hte LegacyExchangeDN Tool. Can this be used with Exchange 2010? Thanks, Matt
