--Moved from StackOverflow--
Our company has been using Comcast as our Exchange provider but we recently set up our own Exchange server running Exchange 2010.
We currently connect to Comcast via Exchange in Outlook.
I was wondering a best practice method for moving emails from accounts on Comcast to accounts on our new server. There are only 7 accounts however some have 30k emails as well as numerous calendar events and contacts.
Any help is much appreciated!
