Remember, this method comes with its drawbacks as it does not migrate calendar items, contacts, etc. and there could be loss of data if not performed carefully.
For a safer alternative, it is recommended to use third party software tools like Zimbra Converter. These tools provide direct and secure data migration from Zimbra to Office 365 with all emails, contacts, calendars, tasks, notes, etc. without any risk of data loss. And the biggest advantage is that they don’t require any technical expertise to use them.
Here’s how you can use Zimbra Converter for this task:
1. Run Zimbra Converter tool on your system.
2. Select ‘Add Files’ or ‘Add Folders’ to load Zimbra TGZ files into the application panel.
3. Choose Office 365 as a saving option from the list of options provided.
4. Enter Office 365 login credentials and hit the ‘Convert’ button to start the conversion.
It might take few minutes to hours depending on the size of your data. Once the process is completed, you can log in to your Office 365 account and find all your Zimbra emails there.
