As of 6 Nov 2026, the panel rates Google Workspace 2.5/5 and Microsoft 365 Business 3/5 in Business Email & Office Suites. Weighted by what each judge cares about, 0 of the 6 judges pick Google Workspace and 6 pick Microsoft 365 Business. Google Workspace scores higher on 2 of 7 criteria (Pricing transparency and European sovereignty). Microsoft 365 Business scores higher on 5 of 7 criteria (Migration, open standards & exit, Calendar, contacts & office apps, Mail, domains & deliverability, plus 2 more). Provenance — Google Workspace: Rest of world; Microsoft 365 Business: Rest of world. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
Microsoft 365 Business holds the higher mean on five of seven criteria: mail and deliverability 7.0 to 5.7, calendar and office 7.5 to 6.0, migration and portability 7.0 to 4.3, administration and identity 6.3 to 5.2, security and compliance 6.5 to 5.8, with six judges leaning its way on mail, calendar and office, and migration. Elsewhere the benches split: security three lean Microsoft 365 Business to three ties, administration four lean to two ties, sovereignty 4.7 versus 4.5 with two judges leaning Google Workspace, one leans Microsoft 365 Business, three tie. Google Workspace is ahead on pricing transparency, 6.8 to 5.8, five judges leaning its way with one tie. Its privacy policy states servers operate worldwide; Microsoft 365 Business pages state customer data continues to be transferred outside the EU Data Boundary in limited circumstances. Judge totals, where published, run 5.1–5.7 for Google Workspace and 5.9–6.6 for Microsoft 365 Business.
Choose Google Workspace if
You need euro prices published for the three business tiers before committing: pricing transparency means run 6.8 versus 5.8, with five judges leaning Google Workspace and one tie.
Your budget process requires billing options beyond annual: the Microsoft 365 Business verdict states annual billing only shown, while pricing transparency leans five judges to Google Workspace, none to Microsoft 365 Business, with one tie.
Your evaluation weights pricing transparency and sovereignty above the other criteria: those are the two means favoring Google Workspace (6.8 to 5.8 and 4.7 to 4.5), with five and two judges leaning its way respectively.
Your data-protection review screens out pages stating outbound transfers: Microsoft 365 Business pages state customer data continues to be transferred outside the EU Data Boundary in limited circumstances, and the sovereignty bench leans two judges Google Workspace, one Microsoft 365 Business, three tie.
Choose Microsoft 365 Business if
You need documented per-plan mail limits and quarantine for your team: mail and deliverability means run 7.0 versus 5.7, with six judges leaning Microsoft 365 Business.
You are moving mail from another platform and want documented entry paths: migration and portability means run 7.0 versus 4.3, six judges leaning Microsoft 365 Business; the Google Workspace verdict found no public information on what its Migrate tool carries over.
Your staff spend the day in Word, Excel and PowerPoint: calendar and office means run 7.5 versus 6.0, six judges leaning Microsoft 365 Business, with the verdict scoring calendar and office 7 to 8.
Your administrators manage identity for many users: administration and identity means run 6.3 versus 5.2, four judges leaning Microsoft 365 Business and two tied.
You must show documented retention to auditors: security and compliance means run 6.5 versus 5.8, three judges leaning Microsoft 365 Business with three ties, and the verdict records retention documented deeply.
Read this comparison as one judge. Each weighs the same scores by what they care about.
The IT Service Provider
Runs a six-person IT service company in Austria that looks after mail for forty client firms, from a two-person architect's office to a hotel group. Spends Mondays on mails that landed in spam and phones that stopped syncing. Wants one partner console for every client, DKIM and DMARC set up without a ticket, migrations it can run itself, support that answers within the hour, and margins it can calculate before it quotes.

This judge's pick
Criterion by criterion
Mail, domains & deliverability
Google Workspace
Custom-domain business mail with documented IMAP (XOAUTH2), send-as aliases with per-address signatures, delegation within the organisation, server-side filter and forwarding rules, and stated spam and phishing protection blocking more than 99.9% of attacks, plus Postmaster Tools for monitoring outbound delivery. We found no public information on SPF, DKIM or DMARC set-up, MTA-STS, native Outlook connectivity, catch-all addresses or an admin-reviewable quarantine — and that DNS authentication work is precisely what fills our Mondays.
Microsoft 365 Business
The Exchange Online service description and limits pages show a platform I could run clients on: ActiveSync with device policies and limits, native Outlook on desktop, web and mobile, a quarantine the admin manages, inbox and transport rules with hard numbers, shared mailboxes up to 100 GB, multi-engine anti-malware and custom outbound routing. But we found no public information on custom-domain DNS set-up, DKIM, DMARC, SPF or MTA-STS, nor on the outbound delivery reputation — the parts I touch every Monday — so I stop short of the top band.
Calendar, contacts & office apps
Google Workspace
Every plan bundles Gmail, Meet, Chat, Calendar, Drive, Docs, Sheets, Slides, Forms, Sites and Keep, with Office-file interoperability, support for over 100 file types, shared drives, appointment booking, e-signatures, and video meetings scaling from 100 to 1,000 participants with recording and attendance tracking. We found no public information on room and resource booking, delegated calendar access, free/busy across providers, CalDAV or CardDAV sync, or the desktop and mobile apps.
Microsoft 365 Business
Calendar, contacts and tasks ship with the hosted service, with conference-room management, resource mailboxes and federated calendar sharing, and the business plans bundle Word, Excel, PowerPoint and Outlook for desktop, web and mobile, Teams, and 1 TB of OneDrive per user. We found no public information on room-booking approval, delegated calendar access or in-browser co-editing, so I hold it just under the top band.
Security, encryption & compliance archiving
Google Workspace
Encryption in transit and two-step verification are stated, the plans add Vault for retaining, archiving and searching data with eDiscovery from the Plus tier, S/MIME on Enterprise, plus DLP, security center, context-aware access and access transparency on the Enterprise tiers, and company data is stated not to be used to train Gemini models. We found no public information on encryption at rest, GoBD-compliant archiving, retention policies and legal hold, a transparency report on authority requests, or certifications such as ISO 27001 or BSI C5 with their scope — the questions my clients' auditors ask first.
Microsoft 365 Business
The retention and legal-hold side is audit-grade: retention labels and policies across mailboxes, Teams and SharePoint, up to 50 holds per mailbox, records with proof of disposition for up to seven years, content search, plus S/MIME signing and encryption, multi-engine anti-malware and deleted mailbox and item recovery. We found no public information on certifications such as ISO 27001 or BSI C5 with their scope, enforced two-factor sign-in, encryption at rest, GoBD archiving or a transparency report on authority requests.
Administration, identity & partner management
Google Workspace
Administrators set data-region policies and view status reports, endpoint management runs from Fundamental through Enterprise with Secure LDAP and Cloud Identity Premium on the top tiers, and the privacy policy confirms domain administrators and resellers manage customer accounts, with support upgrades named Standard, Enhanced and Premium. We found no public information on a partner console for managing several customer organisations, single sign-on, SCIM provisioning, remote wipe, exportable audit logs, or support response times — the things a six-person shop like mine needs before it can promise a client an answer within the hour.
Microsoft 365 Business
For my own tooling this is strong: the Microsoft 365 and Exchange admin centres, remote PowerShell, the Graph API with SDKs to provision users, groups and Teams, usage reports and security alerts, and full Microsoft Entra ID integration with conditional access, identity protection and access-lifecycle governance. We found no public information on reseller or multi-tenant partner accounts for managing several customer organisations, audit-log export, SCIM provisioning or support response times — exactly the gaps that hurt a six-person shop with forty clients.
Migration, open standards & exit
Google Workspace
A Google Workspace Migrate tool is listed from the Standard plan upward, IMAP with XOAUTH2 is documented for read-only extraction and account migration, and account holders can export a copy of their content, auto-delete activity data or delete the entire account. We found no public information on what the migrate tool actually carries over, CalDAV or CardDAV access, an organisation-wide export performed by the administrator, or the handling of data when the contract ends.
Microsoft 365 Business
Getting mail in is documented end to end: cutover up to 2,000 mailboxes, staged and hybrid migration with coexistence for gradual moves, IMAP from Gmail and other systems (mail folders only), a PST import service by network upload or drive shipping, cross-tenant moves, plus FastTrack and partner options. Exit is stated too — cancellation via the admin centre deletes all associated data, with a 7-day right of withdrawal — and Exchange Server remains available as a self-hosted edition; we found no public information on organisation-wide export by the admin in open formats.
European sovereignty
Google Workspace
Administrators can pin covered data to a European Union region, Google Ireland Limited is the named controller for users in the EEA and Switzerland, and a current Cloud Data Processing Addendum is published; the same pages state servers run worldwide with processing outside the user's country possible, and the region option covers only the listed editions — Business Starter is not on that list. We found no public information on named hosting infrastructure, the subprocessors and their locations, or certifications covering the chain.
Microsoft 365 Business
The EU Data Boundary pages commit Microsoft to storing and processing Customer Data for Microsoft 365 tenants signed up in the EU or EFTA inside a boundary with named datacentre countries including Austria, Germany and Switzerland. But the parent company sits in Redmond, Washington, limited transfers outside the boundary continue in stated circumstances, and we found no public information on subprocessors, a published data processing agreement or an EU contracting entity — for my Austrian clients that is a boundary, not full sovereignty.
Pricing transparency
Google Workspace
All three small-business tiers are priced publicly in EUR per user per month — €3.40 introductory and €6.80 regular on Starter, €6.80 and €13.60 on Standard, €10.55 and €21.10 on Plus — with pooled storage of 30 GB, 2 TB and 5 TB, the introductory offer limited to the first 20 users for 12 months for new customers, a stated 16% saving on annual commitment, and a 300-user ceiling on the business plans. We found no public information on VAT treatment, prices for the Enterprise tier and the support upgrades, or the cost of aliases and extra domains — so my margin calculation for a hotel group quote still has gaps.
Microsoft 365 Business
Business Basic at 6,07 € per user per month with annual billing, Business Standard with Copilot Business at 20,36 € and Business Premium with Copilot Business at 27,73 € are published with storage per plan, VAT treatment ("Preise zzgl. MwSt."), trial conditions and a 7-day withdrawal right, and shared and room mailboxes need no subscription. We found no public information on add-on prices for archiving or extra storage, a monthly-billing price for comparison, or minimum users — so I cannot compute a client's full year cost from these pages alone before quoting.
