Understanding Kerio & Microsoft 365

Kerio Mail (Kerio Connect) is an email service/ mail server that allows organisations to manage their emails, contacts, calendars, and tasks. It’s a great option for small to mid-sized organisations that prefer light-weight Email management.

Microsoft 365, on the other hand, is a cloud-based productivity suite from Microsoft that integrates Outlook, Teams, SharePoint, OneDrive, Word, and Excel into one platform. It ensures real-time collaboration, remote access, automatic updates, and enterprise-grade security.

Reasons to Migrate Kerio to Microsoft 365

There are several practical and strategic reasons for switching from Kerio Mail to Microsoft 365:

• Cloud Accessibility: Access your emails and files anytime, anywhere, from any device.
• Better Collaboration: Use Teams, SharePoint, and OneDrive for improved Teamwork and productivity.
• Enhanced Security: Benefit from Microsoft’s built-in anti-phishing, encryption, and compliance features.
• No Server Maintenance: Eliminate the need for managing on-premises servers or manual backups.
• Scalability: It easily scales as your business grows without worrying about storage or maintenance.
• Cost Efficiency: Flexible subscription models reduce IT infrastructure costs.
• Always Up-to-Date: Enjoy regular Microsoft updates with the latest features and patches

Manual Methods to Migrate Kerio Mail to Microsoft 365

There’s no direct manual way to migrate from Kerio to Microsoft 365. However, you can use Microsoft Outlook and the Kerio Outlook Connector as an intermediate solution.

Using Kerio-Outlook Connector

Follow these steps:

1. Open Kerio Webmail and log in to your account.
2. Navigate to Integration with Windows and download the Kerio Outlook Connector.
3. Install and launch Microsoft Outlook on your device.
4. Go to File > Info > Add Account and select Manual Setup or Additional Server Types.
5. Choose Other > Kerio Connect (Kerio Offline Edition) and click Next.
6. Enter your Kerio account details to configure the connection.
7. Once configured, Outlook will create a PST file containing your Kerio emails, contacts, and calendars.
8. Now, add your Office 365 account to Outlook.
9. Import the previously created PST file into Office 365 via Outlook’s Import/Export option.

Your Kerio data will now be available in your Office 365 mailbox.

Drawbacks of This Method:-

While the above method works, it has several constraints:

• Requires installation and configuration of Microsoft Outlook.
• Not suitable for bulk mailbox migrations.
• Time-consuming and complex for non-technical users.
• Risks of data loss or corruption, especially with large attachments.
• Can’t do the customisation and set preferences to get the desired results.
• Manual intervention increases the chances of errors or incomplete transfer.
