Step 01:
Set Up the Migration


❓ Should I enable the option “Ignore Google Bandwidth Limits”?
We recommend to enable this option only if you need to migrate a very large mailbox and are in a hurry. By doing so, MailJerry will migrate your emails to Gmail as quickly as possible, ignoring Google’s bandwidth limitations.
➡️ However, the advantage of moving more data more quickly to Google’s servers comes with the risk that your migration breaks during the process and you need to re-start the migration. To learn more about this option, have a look at this page.
Step 02:
Verify Your Migration

❓ The mailbox check takes very long, is this normal?
Usually, the mailbox check is performed within one or two minutes. But for large mailboxes, the check might take a little more time. So please be patient and wait until the check finished, especially if it takes a few more minutes to analyse an individual folder that contains lots of large emails.

Alternative Methods toMigrate from Office 365 to Gmail
Migrate from Office 365 to Gmail using the Outlook Email Client:
- Drag & Drop: Add your new Gmail account in Outlook and manually drag your data from the old account to the new one.
- PST Export: Export each folder as a PST file and import these files into Gmail.
🚫 Why We Don’t Recommend Outlook for the Migration:
- High Risk of Data Loss: By manually migrating data using Outlook, it’s very easy to forget folders or emails, leading to incomplete or inconsistent migrations.
- Limited Capacity: Outlook struggles with migrating large mailboxes or attachments. The migration can easily break when exceeding Gmails bandwidth limits.
- Extremely Time-Consuming: Manual transfer can take hours or even days, making Outlook an acceptable solution only for very small mailboxes.
- No Delta Migration: New emails received during migration must be moved manually – there’s no automatic sync.
- Long Cutover & Downtimes: Since mailboxes shouldn’t be used during the migration, you need to expect long cutover and downtimes.
- No Data Accuracy: Especially when migrating emails for clients, guaranteeing data accuracy is an important factor, which cannot be fulfilled when manually migrating email data with Outlook.
- No Monitoring or Logs: There’s no progress tracking, summary, reporting or log files that help you to verify and confirm that all email data was migrated to Gmail.
Migrate from Office 365 to Gmail using Gmail’s Migration Tools:
- IMAP Migration Tool
- GWMME (Google Workspace Migration for Microsoft Exchange)
🚫 Why We Don’t Recommend Google’s Native Migration Tools:
- Very Time Consuming: Google migration tools are very slow, because they hone Gmails bandwidth limits to protect their cloud infrastructure. Of course, Google doesn’t offer any workarounds, limiting your migration to a daily upload of 500 MB.
- Complex Setup: Both tools require creating and uploading mapping CSV files – a tedious task prone to configuration errors.
- Risk of Data Loss: GWMME requires to manually export a PST file for every folder, which makes it easy to accidentally skip individual folders or messages.
- Limited Monitoring: Progress visibility is minimal, and Google doesn’t provide detailed logs or error reports.
- Not Suitable for Medium and Large-Scale Migrations: Googles tools might work for small mailboxes but aren’t suitable for professional or enterprise-level migrations due to limited control, validation, and reporting features.
"My mailbox migration is complete and it is commendable that MailJerry outperformed all the migration softwares in the market including Google's own which was really pathetic.
