Migrating your business email and files to Google Workspace (or finally cleaning up a messy Outlook setup) sounds simple until you actually try to do it without losing a single email, calendar invite, or shared drive folder. Search "best Google Workspace migration company 2026" and you'll find dozens of software review roundups comparing tools like CloudM, EdbMails, or MigrationWiz feature-by-feature — but almost none of them tell you what actually matters if you're a business owner or IT lead who just needs the migration done correctly, on schedule, with zero data loss and minimal downtime.
This guide cuts through the tool comparisons and focuses on what actually determines whether a Google Workspace or Outlook setup project succeeds: how to evaluate a provider, what a real project actually costs, what timelines look like in practice, and what red flags to watch for before you sign a contract.
Why "DIY Migration Software" Isn't the Same as a Managed Migration
Most of the top-ranking content for this keyword pushes migration software — EdbMails, CloudM, BitTitan MigrationWiz, Cloudiway, ShareGate, and similar tools. These are legitimate products, and some of them are genuinely good at what they do. But a license alone doesn't migrate your business. Someone still has to:
- Audit your existing mailboxes, shared drives, and calendars before touching anything
- Map user accounts, aliases, and distribution lists correctly between the old and new systems
- Configure MX records, SPF/DKIM/DMARC, and domain verification without breaking mail delivery mid-migration
- Run a pilot migration for a small user group before moving the whole company
- Handle the inevitable edge cases — shared mailboxes, delegated calendars, third-party app integrations, mobile device re-enrollment
- Provide day-one and week-one support once users start hitting "where did my email go" panic moments
A tool handles the data transfer mechanics. A Google/Outlook setup service handles the planning, execution, and support around it — which is where most in-house migrations go sideways. Buying a migration license and assigning it to whoever on staff has the most free time that week is how businesses end up with duplicate calendar invites, missing shared drives, and a week of "I can't find my old emails" support tickets.
What Businesses Actually Get Wrong When Choosing a Provider
Having supported migrations for hosting companies, agencies, and SMBs, the same mistakes come up repeatedly, and they're rarely about the software chosen:
- Picking based on software brand name alone, without checking who's actually configuring it and what their support looks like during cutover weekend
- No dry-run or pilot migration — going straight to a full company-wide cutover and discovering DNS or permission issues only after everyone is locked out
- Ignoring shared resources — shared drives, group calendars, and delegated mailbox access frequently get missed and have to be manually rebuilt afterward
- Underestimating downtime — assuming migration happens instantly rather than planning a maintenance window with proper mail routing during the transition
- No rollback plan — if something breaks mid-migration, there's no way to revert without extended email outages
- Skipping user communication — employees aren't told what to expect, so the moment their inbox looks different they flood IT with tickets instead of following a prepared FAQ
- Forgetting mobile devices and third-party integrations — CRM email sync, helpdesk ticketing integrations, and mobile mail apps often need to be manually reconfigured post-migration, and this step gets skipped when nobody owns the full checklist
What to Look for in a Google/Outlook Setup Provider
If you're evaluating vendors for a Google Workspace or Microsoft 365/Outlook migration, run each candidate through this checklist before you sign anything:
- Pre-migration audit — do they inventory your current mailboxes, storage size, shared drives, and third-party integrations before quoting a price, or do they quote blind based on a headcount number alone?
- Pilot/test migration — will they migrate a small test group first to catch configuration issues before touching the whole company, or is it a single all-at-once cutover?
- DNS and email authentication expertise — can they explain, in plain terms, how they'll handle MX records, SPF, DKIM, and DMARC during cutover without a mail delivery gap? If the answer is vague, that's a warning sign.
- Downtime commitment in writing — a fixed maintenance window, not a vague "should be quick"
- Data integrity guarantee — confirmation that emails, folder structures, calendar events, and contacts transfer intact, with a verification step post-migration where mailbox counts and sizes are checked against the source
- Post-migration support window — at least 5-7 business days of active support after go-live, since most user issues surface in week one, not day one
- Transparent, fixed-scope pricing — per-mailbox or per-project pricing agreed upfront, not open-ended hourly billing that can balloon mid-project
- References or case studies — real businesses they've migrated, ideally in a similar size range and industry to yours
- Ongoing admin support after go-live — Google Workspace and Microsoft 365 both require ongoing admin console management (user provisioning, security policies, storage quotas); check whether the provider offers this beyond the migration itself, since a "migrate and disappear" vendor leaves you without help for the inevitable admin questions that come up months later
CloudHouse Technologies' Google/Outlook setup service is built around exactly this checklist — audit first, pilot second, full cutover third, support afterward — rather than treating migration as a one-click software job. That structure is the actual difference between providers, far more than which underlying migration tool they license.
What Does a Google Workspace or Outlook Migration Actually Cost?
Pricing varies by mailbox count, data volume, and complexity, but as a general guide for 2026:
- Small teams (5-25 users): typically a flat project fee covering account provisioning, DNS/email authentication setup, and mailbox/data migration, usually completed within a few business days
- Mid-size businesses (25-100 users): priced per mailbox with volume discounts, often phased across a pilot group and then the remaining staff over one to two weeks
- Larger or more complex environments (shared drives, multiple domains, legacy on-premise Exchange, custom compliance requirements): custom scoping after an audit, since migration time and cost depend heavily on data volume, integration count, and required security configuration
Be cautious of quotes that are dramatically cheaper than competitors without an audit — that's usually a sign shared resources, calendars, or large mailboxes weren't accounted for, and you'll get hit with change orders mid-project once the real scope surfaces. A provider that quotes a firm number without first looking at your current environment is either underbidding to win the deal or planning to bill you extra later.
It's also worth asking whether the quote includes licensing costs (Google Workspace or Microsoft 365 subscriptions themselves) or purely the migration labor — these are often quoted separately, and conflating them makes comparing providers harder.
How Long Does It Actually Take?
For a small business with under 25 mailboxes and no unusual complexity, a properly planned migration typically runs 2-5 business days from kickoff to full cutover, including a pilot phase. Larger organizations with legacy systems, custom domains, or heavy shared-drive usage should budget one to three weeks, mainly to allow proper testing and phased rollout rather than because the underlying data transfer itself is slow.
The timeline breakdown usually looks like this: a one- to two-day audit and planning phase, a one-day pilot migration for a handful of test users, a short observation period to confirm nothing broke, then the full company cutover scheduled during a low-traffic window (often a weekend or evening), followed by a week of active monitoring and support. Rushing past the audit or pilot phase to save a few days is the single most common cause of migration problems, so a provider promising same-day full-company cutover with no pilot should be treated with caution rather than seen as a selling point.
Google Workspace vs. Outlook/Microsoft 365: Which Setup Do You Actually Need?
Not every business migrating email is necessarily choosing Google Workspace — plenty are moving the opposite direction, from Google Workspace to Microsoft 365/Outlook, or setting up either platform fresh for a new company. A good provider should be platform-agnostic in their advice rather than pushing whichever platform they happen to resell. The evaluation criteria above — audit, pilot, DNS handling, support window, transparent pricing — apply identically whether you're headed toward Gmail-based Workspace or Outlook-based Microsoft 365. What matters is finding a provider comfortable configuring both, since business needs (existing software stack, team familiarity, compliance requirements) should drive the platform decision, not vendor convenience.
Why Hosting Companies/Businesses Choose CloudHouse for Google/Outlook Setup
CloudHouse works with hosting companies, agencies, and growing businesses that can't afford a botched email cutover — where a single missed DNS record or dropped shared mailbox means lost client communication during a critical business window. The difference isn't the migration software used; it's the pre-migration audit, phased pilot rollout, and hands-on post-go-live support that catches issues before they become downtime, plus a team that's comfortable working across both Google Workspace and Microsoft 365/Outlook rather than pushing one platform regardless of fit.
Get Your Migration Scoped Properly
Before you commit to any Google Workspace migration company, insist on a proper audit and a written scope — not just a software license and a hopeful timeline. CloudHouse Technologies' team handles the planning, DNS/email authentication, phased migration, and week-one support so your business doesn't lose a single email or calendar invite in the process.
