I'm working on email migration and during that i need minimum downtime. as of now it being hosted on Google and want to move it the exchange 2007. the domain name is e.g. abc.com and there are 160 plus mailboxes and 10-15 distribution groups. mention this exchange server is already hosting few other domains. what is the best way to do it seamlessly. what my plan is -- create all the accounts under abc.us and once it is created and local email flow is testesd under abc.us then move the MX records to the new Exchange and at the same time apply the policy to change all email aliases from abc.us to abc.com if so then how am i gonna apply the policy.
