The new server is on the domain and some internal mailboxes have been moved to Exchange 2010 and work with no issues. Mail delivery is still via SBS2003. The challenge I have is the SBS2003 server also has BES Express on it and the remainder of mailboxes for users who access remote mail via iPhone or Android. What is the best way to move BES (there are only 4 users with BB’s) Can I move the mailboxes to the 2010 platform and not break the iPhone connectivity? What I would like to achieve is a seamless :-) transition over a weekend of either the iPhone users or the BES users (who are the directors) I’m comfortable with the migration just the BES aspect looks like it could go t**ts up! Any help would be appreciated Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
