Migrate Emails from Gmail to Outlook for Microsoft 365 Adoption

As part of moving away from the current cloud environment (Gmail) and completely embracing Microsoft 365, it is important to comprehensively migrate the current email system along with user accounts, data, chat systems, contacts, and calendars.

Businesses and their IT teams undertaking an email migration project for the first time can have a lot of confusion and may not be aware of the unforeseen roadblocks that can raise the risk of migration disruption.

Therefore, it is important to prepare a structured Gmail to Outlook migration roadmap to avoid errors and ensure smooth adoption.

Here Are Five Key Action Items To Consider For Streamlining The Process Of Migrating Emails From Gmail To Outlook:

1. Decide Whether To Migrate All or Selective Emails

One of the foundational yet crucial decisions to make is to decide whether to migrate all mailboxes from Gmail or choose to migrate them selectively. Both Gmail to Outlook transfer approaches have their unique set of advantages.

• Migrating all mailboxes (full migration/one-time) ensures that your IT team does not miss out on any aspect and performs a comprehensive email migration.
• The selective migration approach helps optimize the email migration project and can reduce the cost of leveraging a professional email migration service in check.

Considering some of these crucial factors may help in deciding whether to migrate all or selective emails from Gmail to Outlook:

• Microsoft 365 adoption goals use cases, such as M&As, cloud cost savings, simplifying cost structures, licensing, etc.
• Complete replication of the source cloud environment in Microsoft 365
• Tight migration deadlines aligned with the upcoming source cloud license expiration.

2. Migrate Contacts and Calendar Syncs

Migrating only emails does not suffice when it comes to performing a comprehensive email migration that ensures a complete replication of Gmail in Microsoft Outlook.

It is also important to migrate other crucial aspects linked to Gmail, including:

• Calendars
• Calendar Events (With Full Syncs)
• Contacts

Migrating these aspects helps ensure that the workflow is not impacted after onboarding Microsoft Outlook.

To achieve this technical feat, it is critical to use a capable email migration tool which helps transfer all emails and their associated features with uncompromised security and zero downtime.

3. Preserve Shared Mailboxes and Distribution Lists

Since shared mailboxes and distribution lists in Gmail make it easy to send emails to a high volume of users in a single go, it is crucial to preserve them when migrating to Microsoft Outlook. Migrating them ensures:

• No disruption in group communication
• Preservation of internal workflows
• Minimal manual reconfiguration in Microsoft Outlook

And since a manual approach can be highly taxing to replicate shared mailboxes and distribution lists, it is a must that your IT team uses an email migration service offering these capabilities.

4. Transfer All or Selective Incremental Changes

It goes without saying that it is crucial to transfer the incremental changes (new emails, edits, deletions) that build up as users continue using their emails while the Gmail to Outlook email migration project is in progress.

However, is it necessary for your IT team to transfer all the incremental email changes that build up over time or transfer them selectively?

Perform an assessment on this with your IT team and finalize whether to migrate all or selective incremental changes via delta e-mail migration. Our email migration tool supports both.

5. Validate the Migrated Emails with Reports

Lastly, make sure to get the validation part right for a successful Gmail to Outlook migration by checking the reports of each email migration batch. Check for vital metrics, such as

• The number of mailboxes migrated (associated with user accounts),
• Calendar migration status,
• Conflict status (if any),
• Time estimates for completing incremental changes
• Overall timeline of the email migration project

Taking this step helps set the right expectations for the planned timeline and ensures transparency.
