Where do I get the Google Cloud service account JSON key needed for migration?

To connect to Google Workspace, EdbMails needs a JSON key file from a service account with domain-wide delegation enabled. Create the service account in Google Cloud Console , configure the required API scopes for Gmail, Contacts, and Calendar, then download the JSON key and upload it during setup.

Is there a limit to how many mailboxes I can migrate with EdbMails?

EdbMails licensing is based on mailbox count, not data volume, so there's no limit on how much data moves within each mailbox you migrate. The free trial lets you test the process first, migrating up to 30 items from each folder before you commit to a license.

Is EdbMails a good G Suite to Office 365 migration tool for large organizations?

Yes. Parallel mailbox processing, CSV-based bulk mailbox loading, and automatic mailbox creation are all built for organizations migrating hundreds or thousands of mailboxes at once, not just small teams.

What's the best way to prepare for a smooth Google Workspace to Office 365 migration?

Start by confirming your Google Workspace admin account has Super Administrator privileges, with API access and a service account configured for domain-wide delegation. On the Office 365 side, make sure target mailboxes have the appropriate license assigned before migration begins. Once both environments are ready, run a pilot migration with a small group of mailboxes first to confirm everything maps correctly before migrating the rest. For the full setup, see the Google Workspace to Office 365 migration guide .

Does EdbMails prevent duplicate emails when migrating from Google Workspace to Office 365?

Yes. EdbMails offers a delta migration feature that transfers only newly added or changed data and skips items that were already migrated, preventing duplicate items in the Office 365 account.

How do I actually perform the migration step by step?

EdbMails walks you through downloading and installing the application, connecting to your source Google Workspace account, connecting to the target Office 365 tenant, mapping source and target mailboxes, and then starting the migration. See the step-by-step guide to migrate Google Workspace to Office 365 for the full walkthrough.

Will users experience downtime during the migration?

EdbMails keeps Google Workspace fully active throughout the migration, so users keep sending and receiving mail as usual while data transfers. Delta migration syncs new or modified items, so nothing gets missed once the switch to Office 365 happens.

Do I need each user's Google Workspace password to migrate their mailbox?

No. The EdbMails Google Workspace to Office 365 Migration Tool connects using a service account with domain-wide delegation, so the admin authorizes access once and all mailboxes can be migrated without collecting individual user credentials. See the Google Workspace admin configuration guide for setup steps.

Can I migrate only specific emails instead of the entire mailbox?

Yes. As a Google Workspace to Microsoft 365 Migration Tool, EdbMails includes advanced filter settings that let you scope the migration by date range, sender, recipient, or CC/BCC address, so you can move only the data that's actually needed instead of transferring everything.

What Google Workspace data does EdbMails migrate besides email?

The EdbMails Google Workspace to Office 365 Migration Tool migrates emails, contacts, calendar events, and tasks, preserving the original folder structure so mailboxes don't need to be reorganized after the move.

What happens if the migration is interrupted due to a network issue?

EdbMails logs migration progress in detail and includes a retry mechanism to handle interruptions. On the next run, this Google Workspace to Microsoft 365 Migration Tool re-syncs only new or changed items through incremental migration, so you don't need to start the entire mailbox over.

How does EdbMails secure data during the migration?

The EdbMails Google Workspace to Office 365 Migration Tool connects to Google Workspace using secure API-based access with domain-wide delegation, and to Office 365 using OAuth 2.0 modern authentication with TLS encryption, keeping credentials and data protected throughout the transfer.

Do I need to install anything on individual users' computers?

No. EdbMails is installed once, and the service account with domain-wide delegation gives it the access needed to migrate every mailbox centrally, so no software or setup is required on end users' devices.

What kind of support is available if I run into issues during migration?

EdbMails includes 24/7 free technical support, so you can reach the team by live chat, email, or phone at any stage of the Google Workspace to Microsoft 365 Migration Tool setup or migration process.

Can I track migration progress while it's running?

Yes. EdbMails shows live status updates as the migration runs, and a detailed report is available afterward so you can verify what was migrated to Office 365.

Do I have to manually map every source mailbox to its Office 365 target?

No. EdbMails offers automatic mailbox mapping based on matching addresses, though you can also map mailboxes manually or import mappings through a CSV file if you need more control.

Can I speed up a large migration by running it on more than one computer?

Yes. EdbMails can be installed on multiple computers, letting you split a large batch of mailboxes across machines to migrate different sets in parallel and shorten the overall project timeline.

Is EdbMails a subscription, or a one-time purchase?

EdbMails uses a one-time license model rather than a recurring subscription, and unused licenses remain available for future Google Workspace to Office 365 migration projects.

Does EdbMails keep a record of what was migrated for compliance or audit purposes?

Yes. Every migration generates a detailed log and report covering the items transferred, which you can review after the migration completes and retain for your own records.

Why Organizations Migrate from Google Workspace to Office 365

Bring email, contacts, calendars and tasks onto one Microsoft 365 platform and simplify IT management during consolidation
or cloud modernization.

Standardizing on Microsoft 365

Many teams already use Microsoft 365 for meetings, files, and chat, but still keep email on Google Workspace. That split makes everyday work harder than it needs to be. EdbMails Google Workspace to Office 365 Migration Tool migrates emails, contacts, calendars, and tasks to Office 365, so the whole team finally works from one platform.

Mergers and Company Consolidation

When two companies merge, staying on two different email systems does not work for long. Usually one side is on Google Workspace and needs to move to Microsoft 365. For broader planning around identity mapping, migration waves, and validation, see Google Workspace migration for mergers and acquisitions. EdbMails migrates multiple mailboxes at once without requesting any individual user credentials, so IT isn't stuck moving accounts one at a time.

Modernizing IT with a Cloud Upgrade

Organizations upgrading their technology often move to Microsoft 365 for better collaboration tools and built-in apps like Teams and SharePoint. EdbMails brings your Google Workspace data to Office 365 fully intact, so the upgrade doesn't leave anything behind. Mailboxes and folders carry over intact, letting teams pick up where they left off.

What Data Can You Migrate to Office 365?

EdbMails covers all the core data types stored in Google Workspace, not just email. Folder structure, metadata, and item-level details are preserved during the transfer, so the destination mailbox reflects the source accurately once the migration is complete.

Email Messages

Attachments

Folders & Labels

Every Gmail message migrates to Office 365 with its original formatting and metadata intact

Files attached to emails migrate along automatically, no separate step required

Gmail's folder structure carries over, so mail lands in Outlook already organized

Contact Details

Contact Groups

Names, phone numbers, and email addresses transfer completely, with no missing fields

Existing groups and categories stay intact, so contacts don't need re-sorting in Outlook

Events & Meetings

Reminders & Details

Calendar events move to Outlook Calendar, keeping dates, times, and attendees in place

Reminders and appointment notes travel with each event

Task Lists

Completion Status

To-do lists and task items move to Office 365 along with everything else

Tasks keep their completed or pending status, so nothing needs re-tracking after the move

Why Choose EdbMails for
Google Workspace to Office 365 Migration

Parallel Mailbox Migration

EdbMails migrates multiple Google Workspace mailboxes to Office 365 in parallel, with the queue replenishing automatically as each mailbox finishes. This scales from a handful of mailboxes to enterprise migrations with thousands of users.

Incremental (Delta) Migration

EdbMails uses an incremental migration approach, transferring only new or modified items on each run. This avoids duplicate data and keeps the destination in sync right up until cutover, with built-in error handling that retries only the items that failed.

Migrate Selective Data

Not every migration needs to move everything at once. EdbMails Google Workspace to Office 365 Migration Tool lets administrators filter by date range, sender, subject, or recipient, so only the data that's actually needed transfers to Office 365.

Maintain Folder Structure

Reorganizing every mailbox after migration wastes time nobody has. EdbMails preserves the original Gmail folder and label structure, so everything lands in Outlook exactly where users expect to find it.

Import User Mapping via CSV

For migrations with multiple mailboxes, source and destination users can be added in bulk through a CSV file. Upload the list once, and EdbMails matches each account automatically, reducing manual effort before the migration begins.

Modern OAuth 2.0 Authentication

Every connection to Office 365 runs through Microsoft's OAuth 2.0 sign-in flow, the same standard used across modern Microsoft 365 applications. No password is ever stored or transmitted at any point in the process.

Zero Server Downtime

Google Workspace stays fully operational throughout the migration, so users keep sending and receiving email without interruption. EdbMails runs the transfer, and the switch to Office 365 happens as a quick final cutover.

Easy-to-Use Interface

No PowerShell scripts or complex configuration required. EdbMails walks administrators through each step, from connecting to Google Workspace to mapping mailboxes, in a straightforward setup that doesn't demand deep technical expertise.
