How to Import MSG to Archive Mailbox? - A Comprehensive Walkthrough!

Office 365 (now Microsoft 365) has become the go-to cloud solution for businesses worldwide, providing robust email services, collaboration tools, and seamless integration. However, migrating your email data from different formats to Office 365 can sometimes be a challenging task. One such format is the MSG file format, which is commonly used for storing individual email messages in Microsoft Outlook.

If you are looking to import MSG to Archive mailbox in M365, this guide will provide you with a detailed explanation of the process, the benefits, and the best tools to help you achieve this. Whether you are an individual user or a business administrator, this article covers everything you need to know about migrating MSG files to Office 365.

What is an MSG File?

An MSG file is a format used by Microsoft Outlook to store a single email message. It contains all the information associated with the email, including:

• Email body
• Attachments
• Subject line
• Metadata like sender, recipient, timestamp, etc.

While the MSG file format is widely used in Microsoft Outlook, it may not always be directly compatible with cloud-based services like Office 365. Hence, migrating these files efficiently to Office 365 is crucial for businesses that wish to centralize their email management.

Why Should You Import MSG to Archive Mailbox?

There are several reasons why you may need to import MSG files to Archive Mailbox:

1. Centralized Email Management: Office 365 offers a centralized platform for managing emails, calendars, contacts, and tasks, which helps businesses and individuals keep everything in one place.
2. Cloud Backup: Migrating MSG files to Office 365 provides an added layer of backup, ensuring your emails are secure and accessible from anywhere.
3. Collaboration: Office 365 facilitates collaboration through tools like Microsoft Teams, SharePoint, and OneDrive, making it easier to share and work on documents, including emails.
4. Migration of Legacy Data: For businesses transitioning to Office 365, migrating older email data from MSG files is a crucial step to ensure continuity in operations.

Now that we understand why migrating MSG files to Office 365 is important, let's dive into the process of importing MSG files.

Manual Methods to Import MSG to Archive Mailbox

Importing MSG files into an archive mailbox in Microsoft 365 (M365) typically involves a few steps, as there’s no direct method to import MSG files into the archive mailbox. However, you can achieve this using either Microsoft Outlook or PowerShell to get the MSG files into the Archive Mailbox of a user. Below is a comprehensive guide for both methods.

Method 1: Using Outlook (Recommended for Small Scale)

If you have a manageable number of MSG files and prefer a manual approach, you can use Outlook to import MSG files into the archive mailbox.

Steps:

1. Ensure the archive mailbox is enabled for the user in M365.
2. Go to the Microsoft 365 admin center > Exchange > Recipients > Mailboxes > Select the user > Enable Archive.
3. Open Microsoft Outlook on your computer.
4. Ensure you are connected to your M365 account to seamlessly import MSG to Archive Mailbox.
5. In Outlook, ensure that the Archive mailbox is visible. You can check it by expanding your mailbox list in the left sidebar. If the Archive mailbox is not listed, make sure it is enabled for the user.
6. Locate the folder containing the MSG files on your computer.
7. Select the MSG files that you want to import.
8. Drag and drop the MSG files into the appropriate folder within the Archive mailbox.
9. Check the Archive mailbox to ensure that the MSG files are successfully added.

Pros:

• Easy for small-scale imports.
• No need for administrative rights or PowerShell.

Cons:

• Not scalable for a large number of MSG files.
• Requires manual interaction.

Method 2: Use PowerShell (Recommended for Bulk Imports) to Import MSG to Archive Mailbox

If you have a large number of MSG files, it’s more efficient to use PowerShell scripts to automate the process of importing MSG files into the Archive mailbox.

Steps:

• If the archive mailbox is not enabled yet, use the following PowerShell command:

Enable-Mailbox -Identity "[email protected]" -Archive

• Open PowerShell and connect to Exchange Online:

$userCredential = Get-Credential

$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Authentication Basic -AllowRedirection -Credential $userCredential

Import-PSSession $session -DisableNameChecking

• Use New-ComplianceSearch to Search and Import MSG Files: PowerShell does not support direct import of MSG files, so you would need to either:

#Use a third-party solution (such as a PST import tool).

#Use the Import PST functionality (which requires converting MSG to PST first).

• Convert MSG to PST to Import MSG to Archive Mailbox (if necessary):

#Use an Outlook client or third-party tool to convert MSG files into a PST file.

#Once the MSG files are converted to PST format, you can import them into M365 using PowerShell.

You can use the New-MailboxImportRequest cmdlet for importing the PST file into the user’s mailbox (including Archive mailbox).

Example:

New-MailboxImportRequest -Mailbox "[email protected]" -FilePath "\\server\path\to\pstfile.pst" -TargetMailbox "[email protected]" -TargetFolder "Inbox"

• Once the import request is completed, check the user’s Archive mailbox to confirm the MSG files have been successfully imported.

Pros:

• Suitable for large-scale imports (bulk).
• Automates the process.

Cons:

• Requires more technical expertise and administrative rights.
• Involves multiple steps for conversion.

Method 3: Use Microsoft 365 Compliance Center (Content Search + eDiscovery) to Import MSG to Archive Mailbox

If you need to import MSG files in bulk and want to use a more sophisticated method, Microsoft 365’s Compliance Center offers content search and eDiscovery tools, though this is typically used for legal or compliance purposes.

Steps:

• Convert MSG to PST: As with the PowerShell method, you’ll need to first convert MSG files into PST format.
• Create a Content Search in Microsoft 365 Compliance Center:

1. Go to the Microsoft 365 Compliance Center > Content Search.
2. Create a search query to look for your MSG files (if already uploaded to OneDrive, SharePoint, or other locations).

• Use eDiscovery Case:

1. Once the content search is complete, you can create an eDiscovery case and export the results.
2. After exporting the data, you can import the exported PST file into the user’s archive mailbox.

• Import the PST to the Archive Mailbox: Use the New-MailboxImportRequest cmdlet to import the PST file into the Archive mailbox, as shown in the PowerShell method above.

Pros:

• More robust for compliance and legal cases.
• Suitable for larger organizations.

Cons:

• Requires familiarity with the Compliance Center tools.
• Involves converting MSG to PST and using PowerShell.
