I’m currently helping a small business move around 15 mailboxes from a GoDaddy-hosted IMAP server to Microsoft 365. At first, I thought the built-in migration wizard would make the process simple, but the results were disappointing. The migration completed, yet several custom folders were missing, and none of the contacts or calendar data appeared in the destination accounts.
While researching ways to Migrate IMAP to Office 365, I realized that Microsoft’s IMAP migration is mainly designed for email messages. Anything outside of standard email content often requires additional steps or separate migration methods. That becomes frustrating when users expect a complete mailbox transfer instead of only inbox emails.
After trying a few alternatives, I tested the DRS Softech IMAP Backup Tool. What stood out was its ability to preserve folder hierarchy and migrate multiple mailboxes in one process. Unlike the manual approach, I didn’t have to spend hours checking CSV files or troubleshooting folder mapping issues. The software handled the mailbox structure properly and reduced the amount of manual work significantly.
For anyone migrating IMAP to Office 365 from providers like GoDaddy, cPanel, or other hosted email services, I’d recommend evaluating your migration method carefully before starting. If your organization depends on retaining mailbox organization and minimizing downtime, an automated approach can save a lot of effort and help avoid incomplete migrations.
As you mention, Microsoft’s built-in IMAP migration has some limitations, especially when it comes to custom folders, contacts and calendar.
To overcome this challenge, Shoviv Software builds dedicated software that makes the migration process easy. Shoviv IMAP to Office 365 Migration software can migrate multiple mailboxes in a single go, while maintaining folder hierarchy. It supports bulk migration of multiple mailboxes simultaneously, which makes it a practical choice for your 15-mailbox scenario. The software connects directly to the source IMAP server and migrates everything to Office 365 without requiring manual CSV mapping or extra configuration steps.
If your IMAP migration skipped your folders and contacts, and now you are looking for the best way to move everything to Office 365.
There are many ways, but according to your needs, you should use an offline solution that keeps your data safe and accurately migrates your folders to Office 365 without any manual effort.
