How to Migrate Office 365 to IMAP Server? Easy Guide

Due to changes in the infrastructure of your email, many companies and professionals will eventually need to migrate Office 365 to IMAP server. Many companies will want to move away from Microsoft 365 to IMAP to decrease their recurring subscription fees; others will want more flexibility with how they manage their email storage, customized servers, mailbox archiving, and mail services that can be supported in privately hosted environments.

In many cases, the user will be ready with an IMAP-based email server and only has to figure out a way to transfer Office 365 mailbox data to that new server without losing any of the information in the transfer. Unfortunately, Microsoft does not have a built-in method available to assist you when migrating from Office 365 to IMAP accounts. The traditional manual process, whereby you synchronize your existing mailbox’s contents using Outlook’s drag and drop feature, is extremely time-consuming and not very reliable for larger mailboxes, and managing the process with multiple users is cumbersome at best.

Microsoft’s Modern Authentication (OAuth 2.0) has also complicated the process to migrate Office 365 to IMAP server, particularly for non-technical users.

Quick Answer: How to Migrate Office 365 to IMAP Server?

There is no method from Microsoft 365 that directly migrates Office 365 email accounts to an IMAP server without manual intervention. Users usually set up both email accounts in Outlook and download their email onto the IMAP server by moving them over one at a time, so this does not reliably work if you have very large amounts of emails to migrate.

A professional Email Backup Software offers the easiest way to migrate Office 365 mailboxes to IMAP. The software directly connects the Microsoft Office 365 platform to IMAP and securely transfers all emails, including attachments, contacts, calendars, folder structure, and email properties.

Follow these few simple steps to migrate Office 365 to IMAP server:

1. Sign into your Microsoft Office 365 email account.
2. Select the folders to migrate.
3. Specify that the destination email account should be an IMAP account.
4. Provide your IMAP credentials.
5. Create and perform the Office 365 to IMAP migration.

Reasons for Office 365 to IMAP Migration

• Reduced Subscription Costs
  Organizations migrate from Microsoft 365 to IMAP-based mail servers, generally to save on the recurring cloud subscription expenses.
