A utility created by vMail can fix any of your Exchange server file problems. This program makes it easier to immediately import the Exchange Server database onto an Office 365 account. It also offers choices for moving to the O365 platform and adding EDB files (if you have any). The tool's ability to get all of your files using your exchange server user id and password is another advantage. Your Exchange database file can be exported to online 365 in the same format as before. One of the many inconspicuous features of this application allows you to filter results to locate and import certain essential Exchange databases into your Office 365 account.
