Switching Hosted Exchange providers
Posted on 2014-09-17
When moving hosted exchange email accounts from one provider to another, I tend to do it in this order:
(1) backup the old account (export it from within Outlook to a .pst file)
(2) update the MX records
(3) wait for the change to propagate
(4) once propagation is complete, re-export the old account in Outlook (to capture any new emails received/sent during propagation)
(5) import it into the new account set up in a new Outlook profile.
My question is this: can I omit point (1)?
This means I am reliant on the second export of emails which is carried out AFTER the MX records have been changed. My worry is that before I've had a chance to go round all users and export their emails, the auto-complete function with Outlook/Exchange could automatically connect Outlook users to the NEW provider and sync with an empty email account, deleting all emails from within Outlook!
