Question is pretty much per subject - for years I have simply used the POP3 email that comes with my hosting, but my needs have outgrown what POP3 can do, so I am looking into getting a hosted exchange account (not with LP

). I need to know what the technical steps are to transfer the email hosting from LP to hosted exchange, and continue receiving email to the addresses I have configured for that domain.
I'm not interested in migrating currently stored messages; these I have saved already in Outlook data files so I'm not so concerned about that.
Where would I find those instructions?
Thanks!
