<h1>Gmail to Outlook, Google Drive to SharePoint, Google Meet to Teams: The Real Migration Guide for 2026</h1>

Most Google Workspace to Microsoft 365 migration guides treat the whole thing as one single event. “Move your data, update your DNS, and done.” But anyone who has actually been through it knows that’s not how it works. The reality is three separate migrations happening at the same time, each with its own quirks, its own failure points, and its own “why did nobody warn me about this” moment.

This guide breaks each workload down individually. Gmail to Outlook. Google Drive to SharePoint. Google Meet to Microsoft Teams. What actually transfers, what silently breaks, and what you need to do before you touch anything.

Why Workload-by-Workload Thinking Changes Everything

Here is the thing most IT teams get wrong. They approach a Google Workspace to M365 migration as one big task and plan accordingly. One timeline, one cutover weekend, one “go live” date.

Then the shared drive permissions break three days later. Or half the team cannot find their files because the folder structure is mapped somewhere unexpected. Or the calendar invites that were supposed to carry over are sitting in Outlook as attachments nobody knows how to open.

The teams that navigate this cleanly treat Gmail, Drive, and Meet as three distinct projects running in parallel, each with its own pre-migration checklist and its own post-migration validation. That reframe alone prevents most of the problems.

Part 1: Gmail to Outlook

What Actually Migrates

The good news first. When you use Microsoft’s native Migration Manager or a tool like BitTitan MigrationWiz, most of what matters does come across cleanly:

Email messages, attachments, and sent items
Folders (Gmail labels are converted to Outlook folders)
Calendars and recurring meeting invites
Contacts

The less good news: Gmail and Outlook organize email fundamentally differently. Gmail uses labels, which means a single email can live under multiple labels simultaneously. Outlook uses folders, where each email lives in exactly one place. When a message carries three Gmail labels, migration tools typically create three copies of it in Outlook, one per folder. Your storage usage goes up slightly. Your users get confused until someone explains it.

The Hidden Problem: Large Emails and Silently Skipped Items

Migration Manager will not move emails larger than a certain size threshold, and it will skip emails silently in some cases rather than flagging them as errors. Before you start, run a mailbox size audit. Any attachment-heavy users, engineers who email CAD files, and finance teams forwarding PDF packages are the ones who will notice missing items first.

Back up with Google Takeout before you begin. It takes an afternoon, and you will be very glad you have it if something goes sideways at 11pm on a Saturday.

Calendar and Contacts: The Underestimated Piece

Calendars migrate reasonably well for individual events. Shared team calendars are where things get messy. A shared “Company Holidays” calendar in Google can arrive in Outlook as 47 separate copied events distributed across individual calendars rather than one clean, shared calendar. Plan to rebuild shared calendars in Microsoft 365 post-migration rather than relying on automated transfer.

Contacts need to be exported from Google Workspace as a CSV and imported into Exchange Online. It is manual, it is slightly tedious, and it is absolutely worth doing properly so your team is not hunting for client phone numbers the morning after cutover.

Timeline Tip

Migrate email in waves, not all at once. Start with a pilot group of 5 to 10 people, including at least one executive, one heavy email user, and one person who will actually tell you what broke. Fix what they find, then scale to departments.

Part 2: Google Drive to SharePoint (and OneDrive)

This is where most migrations get into trouble. Email is relatively forgiving. Drive permissions are not.

The Mapping Logic You Need to Know Upfront

Google Drive and SharePoint organize files differently, and their permission models are not equivalent. Before a single file moves, you need to decide how your Google Drive structure maps to Microsoft 365:

Google Workspace

Microsoft 365 equivalent

My Drive (personal)

OneDrive for Business

Google Shared Drive (team)

SharePoint Team Site

Google Shared Drive (project)

SharePoint Document Library or Teams channel

Google Drive folder

SharePoint folder or document library

Getting this mapping wrong is the single most expensive mistake in any drive migration. A file that lands in the wrong SharePoint site means manual cleanup for weeks afterward.

What Breaks With Permissions

Google Drive permissions map roughly as follows: Viewer becomes Read, Commenter becomes Contribute, and Editor becomes Edit in SharePoint. The one permission that cannot transfer is Owner, which reverts to the destination site administrator.

The deeper problem is inherited permissions. In Google Drive, you can grant broad access at a parent folder level and then selectively restrict child folders. SharePoint handles inheritance differently, and when migration tools encounter a Google Shared Drive folder structure with selective restrictions, the results are unpredictable. Some files end up accessible to people who should not see them. Others become inaccessible to people who should.

The fix is to audit every Shared Drive’s permission structure before migration, document who should have access to what, and manually configure SharePoint site permissions before you move a single file. Yes, this takes longer. No, there is no shortcut that does not cause problems.

What Does Not Migrate at All

Google Sites, Maps, and Apps Script files are not supported by Migration Manager and will not transfer. Google Docs, Sheets, and Slides convert to Word, Excel, and PowerPoint formats automatically, but embedded Google-specific features like linked charts that pull from a Google Sheet live will break. Any custom Google Apps Script automations your team relies on need to be rebuilt in Power. Automate before migration completes. Inventory these before you start. Discovering them afterward is a very unpleasant surprise.

The 400-Character Path Limit

SharePoint has a 400-character limit on file path lengths. Google Drive does not. In companies that have been using Google Drive for years, it is surprisingly common to find deeply nested folder structures where the full path exceeds this limit. Migration Manager will skip these files rather than failing loudly. Run a pre-migration scan, identify paths over 400 characters, and restructure them in Google Drive before the migration begins.

Part 3: Google Meet to Microsoft Teams

Of the three workloads, this is the one businesses tend to underestimate most. Meet and Teams are not equivalent products. Migrating to Teams is not just switching video conferencing apps. It is a collaboration platform change that affects how your team communicates, organizes projects, and accesses files every day.

What Actually Transfers

Honestly, not much migrates automatically from Meet. There is no native tool that moves Google Meet recordings, chat history, or room configurations to Teams. Recorded meetings stored in Google Drive can be moved to SharePoint or OneDrive as video files during the Drive migration, but they will be static video files, not Teams meeting recordings with transcripts and chapters.

Google Chat history also does not migrate to Teams. If your organization needs to retain historical chat records for compliance purposes, export and archive them through Google Vault before decommissioning Google Workspace. Do not skip this step.

Setting Up Teams the Right Way From the Start

The biggest Teams mistake is letting it grow organically after migration. Without a governance plan, you end up with 200 Teams created by different people for overlapping purposes, nobody knows which channel to post in, and adoption collapses within three months.

Before go-live, define the following:

Which teams will exist and who owns them (map these to your existing Google Groups where possible)
Naming conventions for Teams and channels
Which information belongs in Teams chat versus email versus SharePoint
Who can create new Teams (not everyone, by default)

Set these policies in the Microsoft Teams admin center before your first users log in. It is genuinely much harder to retrofit governance than to start with it.

Replacing Google Meet Features Your Team Relies On

A few things Teams does that Meet does not, which actually makes this an upgrade for most organizations:

Persistent chat history organized by channel and topic
File sharing directly in channel context, stored in SharePoint
Meeting recordings with automatic AI-generated transcripts (via Microsoft Copilot)
Integration with Outlook calendar for meeting scheduling
Breakout rooms, polls, and collaborative whiteboards built in

The features your team used in Meet, video calls, screen sharing, and quick one-on-one calls all work in Teams. The learning curve is the interface, not the capability. Budget two weeks of user adjustment time and run short role-based training sessions rather than one long all-hands walkthrough.

Step-by-step guide to migrate Gmail to Outlook, Drive to SharePoint, and Meet to Teams in 2026. Tools, tips, and best practices explained.

The Order That Makes Everything Easier

If you are running all three workloads simultaneously, do them in this sequence:

Set up your Microsoft 365 tenant and configure security, DLP, and governance policies first
Migrate identity (users and groups) from Google to Microsoft Entra ID
Configure SharePoint sites and Teams structure before any data moves
Migrate Drive to SharePoint and OneDrive, validate permissions
Migrate Gmail to Outlook in waves, starting with the pilot group
Run Teams training while email migration completes
Update MX records to point email to Microsoft 365 (the official cutover moment)
Keep Google Workspace in read-only mode for 30 days minimum before decommissioning.

Step 3 is the one most teams skip. Configuring your destination before moving data prevents the cleanup work that otherwise consumes weeks post-migration.

Frequently Asked Questions (FAQ)

Does Google Drive migrate to OneDrive or SharePoint?

Both, depending on the type of content. Personal files from individual My Drive accounts typically migrate to each user’s OneDrive for Business. Team content from Google Shared Drives migrates to SharePoint Team Sites. The mapping decision should be made before migration begins, documented, and communicated to users so they know where to find their files after cutover.

Will my Google Meet recordings transfer to Microsoft Teams?

No, Google Meet recordings do not migrate automatically to Microsoft Teams. Recordings stored in Google Drive will move to SharePoint or OneDrive as video files during the Drive migration, but they will not appear as Teams meeting recordings with transcripts or chapters. If you need to retain recordings for compliance purposes, export them through Google Vault before decommissioning Google Workspace.

How long does it take to migrate from Google Workspace to Microsoft 365?

The timeline depends on the size of your organization and the complexity of your data environment. A straightforward migration for 50 to 100 users with clean data typically takes four to six weeks from planning to full cutover. Mid-sized organizations in the 200 to 500 user range with complex shared drive structures and compliance requirements generally need eight to twelve weeks. Enterprise deployments above 500 users with multiple departments, compliance obligations, and custom integrations should plan for three to six months. The largest driver of timeline overruns is discovering unmapped Apps Script automations or broken permission structures mid-migration, which is exactly why pre-migration audits exist.
