If you’re a Rackspace user, you may have been affected by the recent cyberattack that caused a massive outage on their Exchange Server. As per the last update, Rackspace recommends that users migrate their emails to Microsoft 365 & even offer free licenses until their servers are back online. It can be a confusing task for those unfamiliar with the migration process, especially when dealing with OST files. Don’t worry, as we will guide you through the process of migrating from Rackspace Hosted Exchange OST files to Microsoft 365 so that your emails will be accessible without any hassle.

Method 1: Migrate Rackspace Hosted Exchange OST File to Microsoft 365 via EAC

The Exchange Admin Center (EAC) is the most viable platform for executing this transition. Here are steps to follow when migrating:

1. Prepare your existing Rackspace environment
   Before migrating to Microsoft 365, it’s crucial to review Rackspace so that the data is optimal for the migration. This step includes reviewing mailboxes, distribution lists, contacts & user accounts, as well as securing all necessary permissions for access.
2. Obtain the Rackspace server details
   To initiate the migration process, you need the details of the Rackspace server hosting your mailboxes. Navigate to your Rackspace account & obtain this vital information. Specific login steps to locate the details may vary depending on the Rackspace email account type.
3. Select a suitable Microsoft 365 license plan
   Choosing the right Microsoft 365 license plan that suits your organizational needs is vital before starting the migration. Understand the features, capabilities & costs & choose the plan that best fits your organization’s requirements.
4. Create the Migration endpoint & migration batch.
   Connect to Exchange Online & set up a migration endpoint via the PowerShell cmdlets. An endpoint is a location that Exchange Online uses to communicate with the on-premises or hosted Exchange organization. Create a migration batch with a CSV file & define the source email account & its password, target email account & other relevant settings. After verifying the endpoint, start the migration batch.
