Methods for Migrating Outlook Emails to Office 365
There are two ways to migrate Outlook to Office 365, either by using a built-in tool offered by Microsoft or by using professional solutions that are recommended by Microsoft MVPs.
If you follow the approach offered by Microsoft then this task can be done in two different ways:
- Network Upload: In this method, you need to import PST files over the temporary Azure storage and then use Import service for the migration of mailboxes.(Free method)
- Drive Shipping: You need to Copy all the PST files into a BitLocker hard drive and ship that drive to Microsoft. Then, Microsoft will upload the PST file itself into your account (Cost - $2 USD per GB).
Important Note: Both the method mentioned above are for the high technical users. The technique doesn’t cover planning and preparation required, like checking for corrupted PST, removing passwords, etc. All those steps need to be done manually prior to the migration procedure.
Issues With Office 365 Import Service of Microsoft
The Import Service provided by Microsoft for its Office 365 users for migrating Outlook emails to Office 365 account is a straightforward tool. However, there are several disadvantages or weaknesses that should be aware of before using this tool.
- Password: Admin needs to add passwords for each user manually, either by getting passwords of each user or resetting each account password.
- No option to handle duplicate PST file: When a user is migrating multiple Outlook PSTs then there could be a chance of uploading the same pst. This tool will upload the same PST again without warning
- Outlook PST file Elimination: Users need to separately handle the disconnection of Outlook profile from PSTs and prevention from the creation of a new PST file.
- Identifying the right owner: This service doesn’t assist in identifying the owner of Outlook PST files, this needs to be done manually by the user.
Note: If you are a non-technical user, or don’t have proper resources then we will recommend you to opt for more professional solutions which are safe and secure.
