Is it possible to have three diffferent Blackberry devices each one of them configured to access to the same Exchange account (mail, calendar, contacts) via BES?
If I read an email on a BB, the message should be flagged as read on other two, if I delete or move a message on a device or if I modify/create a calendar entry, I must see the same changes on all the devices.
Now the user has 3 BB devices configured with 3 different accounts with BES and Lotus Domino. A feature of Domino keeps the three accounts synchronized, but I did not find such a feature on Exchange 2010
Update: Since BB does not support multiple device accessing the same email, the only solution by now seems to create different accounts and synch them with Exchange Sync http://www.codetwo.com/exchange-folder-sync/
