Your e-mails are stored on our servers and backed up every evening. Kept for 30 days if problems arise, they can still be accessed for 14 days after being removed. The processing and archiving of your e-mail data are not outsourced: with us you know where your information is stored.
Synchronized with all your machines, Exchange lets you share your calendar with all your close staff, who can update it according to parameters you have defined.
No need to use your server to host your e-mail: MBS offers the Hosted Exchange service and maintains it.
