If your organization is moving away from Google Workspace and switching to Exchange Server, you are not alone. A lot of companies make this move for different reasons, and the good news is that with the right tool and a bit of planning, it is not nearly as painful as it sounds.
This article covers why companies switch, what you need to prepare, and how to actually get the migration done using EdbMails G Suite Migration Tool .
Why Do Organizations Move from G Suite to Exchange?
Google Workspace works well for many businesses, but it is entirely cloud-based and runs on Google’s infrastructure. That means you are working within Google’s rules, Google’s storage limits, and Google’s security model.
Exchange Server flips that. Your IT team runs the mail server directly, whether on-premises or in a hybrid setup. You get full control over security policies, retention rules, mailbox sizes, and where your data actually lives. For industries like healthcare, finance, or government, that level of control is often a legal or compliance requirement, not just a preference.
There is also the Microsoft ecosystem angle. If your organization already runs Active Directory, SharePoint, and Teams, having email sitting on Google Workspace creates extra friction. Moving to Exchange just makes everything work together more smoothly.
What EdbMails Does for This Migration
EdbMails has a dedicated G Suite Migration Software that handles the transfer of Google Workspace mailbox data to Exchange Server. It connects to Google Workspace through secure APIs using a service account with domain-wide delegation. In plain terms, you set up one admin connection and EdbMails can access all user mailboxes without you needing to log into each account individually.
On the Exchange server side, it allows connection using a Global Administrator account, so there is no need for individual user passwords.
What gets migrated? Gmail emails, attachments, folder labels, contacts, calendar events, and tasks. Folder hierarchy, email metadata like sent dates and read/unread status, and mailbox structure are all preserved. It supports Exchange Server 2007, 2010, 2013, 2016, and 2019, plus hosted Exchange environments.
For bulk migrations, EdbMails processes multiple mailboxes at the same time rather than going one by one, which saves a lot of time. It also supports incremental migration, meaning if you run the process more than once, only new or changed items get transferred. No duplicates.
Before You Start: What to Check
A little prep work here goes a long way.
On the Google Workspace side, you need a Google Workspace admin account with Super Administrator privileges. API access needs to be enabled in the Google Workspace Admin console, and you need to set up a service account with domain-wide delegation. EdbMails has a step-by-step guide for this.
On the Exchange server side, make sure Exchange Web Services (EWS) is enabled and reachable from the machine running EdbMails. You need an Exchange admin account with impersonation rights, or an account with full access permissions to all target mailboxes. If you are migrating to hosted Exchange, have those server details and credentials ready before you start.
General prep: make a list of all the G Suite mailboxes you are moving and their corresponding Exchange email addresses. If the source and target addresses are different, you will need a mapping file. Back up your Exchange environment before anything else, and schedule the migration outside of peak business hours.
Step-by-Step: G Suite to Exchange Migration Using EdbMails
Step 1: Download and install EdbMails. Download the G Suite Migration Tool from EdbMails website and install it on a Windows machine that can reach both the Google Workspace environment and the Exchange server. The free trial lets you test with a limited number of items before buying.
Step 2: Configure the Google Workspace admin account. Set up your Google service account with domain-wide delegation and the required API scopes in the Google Workspace Admin console and Google Cloud Console. This is a one-time setup.
Step 3: Connect to your G Suite account. Open EdbMails and choose G Suite Migration. Enter your Google Workspace admin email and upload the service account JSON key file. Click Connect. EdbMails authenticates with Google and pulls up the full list of mailboxes in your organization.
Step 4: Select which mailboxes to migrate. You will see all available G Suite mailboxes. Pick individual ones, select all, or import a CSV file of email addresses. For large organizations, the CSV approach saves a lot of time.
Step 5: Connect to the target Exchange server. Enter your Exchange server address, admin email, and credentials. Choose your connection method based on how your Exchange environment is set up: Global Admin, full access permissions, or a CSV file for per-user credentials. For hosted Exchange, enter those server details here.
Step 6: Review mailbox mapping. EdbMails automatically matches G Suite mailboxes to Exchange mailboxes by email address. Go through the mapping list and fix any mismatches before you proceed. A wrong mapping sends someone’s email to the wrong account, so take a few minutes here.
Step 7: Set filters if needed. You can limit what gets migrated by date range (for example, only the last two years) or by specific folders like Inbox and Sent Items. This is useful if you want to do a staged migration, bringing over recent data first and older archives later.
Step 8: Start the migration. Hit Start Migration. EdbMails processes multiple mailboxes at the same time, so you can watch progress per mailbox in real time including item counts, folder status, and any errors. Do not disconnect from either server while it is running.
Step 9: Check the migration reports. After migration finishes, EdbMails generates per-mailbox reports. Review them to confirm emails, contacts, calendar events, and folders all came through correctly. Save these reports as your audit trail.
Step 10: Run incremental migration before cutover. Users were still working in Google Workspace during the migration, so new emails will have landed after the initial transfer. Run incremental migration to pick those up. EdbMails skips everything it already moved, so no duplicates. Run this as close to your cutover time as possible.
Step 11 — Switch users to Exchange. Once you have verified the migration reports and run the final incremental pass, update DNS MX records to point to the Exchange server, reconfigure users’ email clients to connect to Exchange, and retire their Google Workspace access. Communicate the cutover date to users in advance so they know what to expect.
Key Features That Actually Matter for Bulk Migration
A few things in EdbMails make a real difference when you are moving a large number of mailboxes.
Concurrent migration processes multiple mailboxes at once instead of queuing them up one after another. That alone cuts total migration time significantly. Incremental migration lets you re-run the process without worrying about duplicates, which is essential for any migration that spans multiple days. Automatic mailbox mapping saves hours of manual work. Throttle management handles API rate limits on both the Google and Exchange sides automatically, so the migration keeps moving even when the servers try to slow it down. And since EdbMails runs in the background while users stay on Google Workspace, there is no forced downtime at any point.
Mistakes That Catch People Off Guard
Turning off Google Workspace too early. Check the reports first. Confirm every mailbox transferred fully before you retire any Google accounts.
Skipping the final incremental sync. Anything that landed in Google Workspace after your initial migration run will not be in Exchange unless you do that last incremental pass right before cutover.
Getting the service account set up wrong. This is the most common reason the connection to Google fails. The service account needs the correct API scopes and domain-wide delegation. Follow EdbMails’ guide exactly rather than trying to figure it out from scratch.
Jumping into the full migration without a test run. Run five to ten mailboxes first. It takes an extra hour and saves you from discovering a configuration problem when you are halfway through migrating 300 users.
Only spot-checking email. Contacts and calendar items are easy to overlook. Verify that those were transferred correctly in a handful of test mailboxes before you wrap up.

Conclusion
Migrating from G Suite to Exchange is a real project, but it is manageable with the right preparation and a tool that handles the technical side properly. Get your service account configured correctly, map your mailboxes carefully, run a pilot batch first, and make sure you do that final incremental sync before cutover.
