Solutions to Restore Office 365 Mailbox from Backup
If we discuss the solutions, you can restore Office 365 emails from a previous backup using manual or automated methods. We will discuss both in this article, so keep reading!
#1 Manual Methods to Restore Microsoft 365 Mailbox
The manual methods for restoring Office 365 mailbox from a previous backup involve three tools from Microsoft: The Import/Export feature (found in Outlook), the Network Upload Method, and the Drive Shipping Method. Let’s read about them all one by one.
Import/Export Wizard
The Import/Export Wizard in Outlook is the easiest way to import/export emails to Office 365. You can also import contacts and calendars using this tool.
Let’s see how to import your emails:
- Open the Outlook application and go to File in the ribbon on top.
- Select Open & Export and click Import/Export.
- Once the Import & Export Wizard opens, choose Import from another program or file and click Next.
- Select Outlook Data File and click Next.
- Click on Browse to select the Office 365 mailbox PST file.
- Select Do not import duplicates and click Next. Select the Include subfolders option to ensure the data hierarchy and click Next.
- Select Import items into the same folder option and choose the configured Office 365 account. Click Finish.
There are a few drawbacks to this method of migrating Office 365 mailbox emails, and they are:
- You can restore only one mailbox at one time, making this process lengthy.
- There is no guarantee of complete data restoration to Office 365.
- This method doesn’t have any import reports.
Network Upload Method
The second free method to restore Office 365 emails from backup is the Network Upload method using Azure AzCopy. Follow this guide to use this process:
- Copy the SAS URL and install Azure AzCopy.
- Upload the PST file you made to Office 365.
- Create a PST Import mapping file.
- Create a PST Import job for Outlook in Office 365.
- Use Filters to import PST to Office 365 shared or primary mailbox.
Limitations of this method
- The process is complex, time-taking and not available in some regions.
- The process has to get repeated to export more email accounts to Office 365.
Drive Shipping
Another method you can use to restore Office 365 mailbox from backup is the Drive Shipping method which involves copying the Office 365 PST data onto a hard drive & shipping it to one of the physical locations of Microsoft. And another thing to note about this method is that only the admins and the companies migrating the email data should use it.
Follow these steps to restore Office 365 emails:
- Download the secure storage key and a PST Import tool.
- Use the tool to copy the PST file into a hard drive.
- Create a PST mapping file.
- Ship the hard drive to Microsoft with a tracking number.
- After Microsoft receives your hard disk and finishes working on it, start filtering the data and create an Outlook PST Import job.
Limitations of this method
- You need to send the data to Microsoft on a hard drive physically.
- The process is time-taking (1-2 weeks) and expensive ($2 per GB), which many companies can’t afford.
- Network Upload and Drive Shipping methods are highly technical, and many Outlook users avoid them because they don’t have the expertise to use them.
#2 Automated Method to Restore Office 365 Data
The manual methods described above fall short of restoring the Office 365 mailbox because the Import/Export Wizard can import or export only a single PST file at a time, and the latter two methods are technical and involve expertise to use them, leaving no option for Outlook users to migrate emails manually.
