We have enterprise users that want to try out an online mail provider (such as GMail or MS Exchange Online) for a trial period, but would also like their local mail (Lotus Notes) to remain synched with the trial account so that they can compare and contrast and maintain their normal work routine both in the cloud account and in their 'local' accounts.
What is the best way to achieve a seamless 'mirroring' of both email accounts for each user so that
- emails delivered to either account will appear in the inbox of both accounts
- emails sent from either account appear in on both accounts in the 'sent items' folder
- emails moved from one folder to another in one account will automatically reflect on the other account (this is a 'nice-to-have').
The key word here is seamless. Emails sent/delivered to/from either account should retain their original senders and sendees.
Is this even possible?
