We are scheduled to migration our Exchange server to a new domain using export / import. The issue we are most concerned about is post-migration calendar appointments which will still have the old domain emails. Appointments are updated frequently across the board (time and date changes, new or updated agendas, new attendees), so will users have to manually update each appointment and replace the old domain email addresses with new domain email addresses if the appointment changes post-migration? Are there any tools out there that would do this switch during a migration?
Thanks in advance,
