You may have collected hundreds or thousands of .pst files over the years, scattered around users’ computers, shared folders, and USB drives. We will help you find, collect, and migrate these files to Exchange Online so you can forget about archiving to .pst forever.

    We perform an Outlook .pst file migration to Microsoft Office 365 (Exchange Online). Importing .pst files to user mailboxes is one way to migrate your organization's email, tasks, calendars, and contacts to Office 365.

    We have two possible ways to import .pst files to Office 365. The first way is to upload the data files over the network to temporary storage in the Microsoft cloud. The second way is to copy the .pst files to a hard drive with BitLocker encryption and then physically ship the drive to Microsoft.

    Export and collection of .pst files can be performed either by IT Partner or the Client, upon agreement.

    9. Change DNS settings and control their application
    10. Monitor health and status of the destination Exchange Online environment to make sure the migration process is correct
