The problem with replying to old emails from users in the existing exchange organisation, is that exchange doesn't store the email address of the user who sent the message. Rather, it stores the DN (distinguished name) of the user who sent the message, i.e. /o=some org/ou=something/cn=recipients/cn=theuser , rather than SMTP:[EMAIL PROTECTED] This is basically what allows you to see the full details of a user when you double click on their name in outlook (it uses the DN to query the directory to get the information).
Therefore, the new Exchange server won't know who the old person was to reply to email, because the DN of the new user account is different to the old one. If you use the available migration tools to migrate accounts, the "LegacyExchangeDN" attribute can be populated on the Windows 2000 accounts, and Exchange 2000 will use this for replying to old emails, making everyone happy Migrating content via PST's is ok, but use the migration tools to push accounts into Win2k AD so that the legacy attribute gets populated (or script it), otherwise it could get very ugly very quickly. To see this in action, open a PST file with messages in it from inside the organisation on an outlook client that has no knowledge of your environment (disconnected outlook client, no offline address book etc). Open the message, and double click on the sender. The display name will be populated with the DN, and all other fields will be blank. This will also affect calender items etc as discussed below. I'm sure someone will correct me if this is wrong :) Glenn ----- Original Message ----- From: "Bennett, Joshua" <[EMAIL PROTECTED]> To: "Exchange Discussions" <[EMAIL PROTECTED]> Sent: Wednesday, February 19, 2003 8:16 AM Subject: RE: Migration Scenario > If we export everyone's mail to a PST and re-import onto the new server will > this still cause issues with replying to old emails?
