[tming]

Hello,

Our company have a remote and main office. We are going to migrate the mail from remote to main ofice.
We are using exchange 2000 in main office.
Our remote use using a mail service provided bu ISP.
We decide to move the mailbox of remote from ISP to main office.

Our high level plan is try download all mail from ISP to remote users's mailbox.
Then redirect all mail of remote to main office.
Actually, i don't have such experience.
Can any one tell me more detail in step.

Environment:

remote user : mail1@remote.com
main office : mail2@mainoffice.com

What i have to do on the IPS side.
Also, for the exchange, how to hold more than domain and what i have to do in main office ISP for MX record.

Can anyone help?
Thanks a lot
