Enterprise-level organizations are moving away from traditional office-bound setups like those in SquirrelMail.

The easiest approach is to use a specialized tool, the Cigati IMAP Backup Tool. It directly migrates the SquirrelMail emails to Office 365 while ensuring that data remains intact.

Organizations migrate the SquirrelMail emails to Office 365 to modernize their email management system. They can perform this migration using the IMAP protocol and by using the Cigati IMAP Backup Tool. 

Elodie Martin from France asks: “I run a small business in France. We are planning to move from SquirrelMail to Microsoft 365 because we need better collaboration and security features. We have several user mailboxes with thousands of emails, attachments, and custom folders, so I am looking for a professional migration tool that can transfer all data without losing folder structure or metadata.”

What is the Need to Migrate Mail from SquirrelMail to Office 365?

The primary need for the SquirrelMail-to-Office 365 migration is to migrate to a modern application with improved security. Take a look at the following points where this migration is needed:

• The unmaintained SquirrelMail software no longer receives updates and bug fixes, unlike Office 365, which regularly receives updates. 
• There are security vulnerabilities with SquirrelMail as it does not keep pace with modern security risks. Office 365 provides advanced security protocols. 
• Office 365 offers a suite of business tools, including productivity and collaborative tools. 
• Microsoft guarantees 99.9% uptime under a financially backed SLA to maintain uninterrupted business operations. 
• With Office 365, users can seamlessly access their mailboxes across devices and enjoy automatic email synchronization. 

Top Methods to Migrate SquirrelMail to Office 365 

After reviewing the needs of this email migration, let us now learn about the solutions. In this section, we have listed two solutions: a manual solution that uses IMAP and an automated solution that directly migrates emails. 

Manually Transfer SquirrelMail Emails to Office 365

In this approach, we will first download all the mailbox data of SquirrelMail and then import it into Microsoft 365 as a PST file. It is an easy approach and is suitable for small-scale migrations.

Use the following steps to begin the migration process:

Step 01: Export SquirrelMail Mailbox to a PST File

1. First, open Microsoft Outlook and add the SquirrelMail account via IMAP. 
2. Once the account is added, let it sync the data, and then review the email data.
3. Now, head to the File menu tab and click on Open & Export > Import/Export.
4. After that, press Export to a file > Outlook Data File (.pst) and choose the SquirrelMail mailbox to export.
5. Then, pick a location to save the resultant PST file and hit the Finish button. 

Step 02: Import the PST File into Office 365 

1. In MS Outlook, navigate to File > Add Account and enter the Office 365 account credentials.
2. Then, go to File > Open & Export > Import/Export > Import from another program or file.
3. Next, select Outlook Data File (.pst) and choose the exported PST file.
4. Pick the destination location as Office 365 mailbox and click on the Finish button.  

Drawbacks: Large organizations have multiple user accounts with data that can’t be migrated with this manual approach. It becomes unreliable for large datasets. Also, the contacts, tasks, calendars, and notes are not migrated. 

Why Manual Solution Fails at Enterprise-Scale?

Generally, the manual process does not guarantee security and data privacy. When migrating at a large scale, it does require a professional solution. Below are a few reasons why manual processes fail in an enterprise organization:

• The native IMAP migration can only handle a few mailboxes at a time. This makes it inefficient for organizations that have large datasets.
• Also, the manual migration process does not prevent the same message from appearing twice. It leads to duplication of emails.
• User’s account credentials can get exposed while entering the details manually via the IMAP server.
• It takes a considerable amount of time while handling 1000 mailboxes at once. In this case, a dedicated tool is required.
