What this page answers
The main decision questions link directly to the detailed, source-backed answers on this page.
Evaluation criteria
4 criteria to evaluate separately
Model access
Compare more than model count: evaluate approvals, availability, regions and the practical ability to switch between model providers.
Company knowledge
Evaluate which internal sources can be connected, how source permissions are preserved and whether answers can be traced back to evidence.
Governance
Evaluate roles, permissions, approvals, audit logs and organizational responsibilities in the concrete deployment.
Hosting and data region
Do not treat storage region, processing region, model region and possible third-country transfers as the same commitment.

How do the documented offers differ?
| Criterion | Microsoft 365 Copilot |
|---|---|
| Company focus | Microsoft 365 Copilot: AI inside Microsoft 365 workflows. [23][25] Microsoft now also uses the name Microsoft Copilot for the offer. This page concerns the business offer, not consumer Copilot. |
| Model access | Microsoft 365 Copilot: external model options also exist. [23][24] Anthropic is not enabled by default in the EU, EFTA and UK and is currently outside the EU Data Boundary. Individual models have additional conditions. |
| Company knowledge | Microsoft 365 Copilot: Microsoft Graph and work context. [23][26] Copilot Chat without the relevant licence scope is not equivalent to automatic access to all company data. |
| Integrations | Microsoft 365 Copilot: connectors, agents and MCP apps. [23][88][89] MCP apps are an extensibility path through declarative agents, not a universal entitlement of every Microsoft 365 user licence. Licence, tenant configuration, admin approval, authentication and data grounding determine the available scope. |
| Governance | Microsoft 365 Copilot: policy controls in the Microsoft environment. [25] Protection follows the actual permissions. Over-broad source access is not automatically fixed by AI. |
| Administration | Microsoft 365 Copilot: Microsoft administration. [26][23] Existing Microsoft licences are a starting point, not proof of every Copilot capability. |
| Agents and workflows | Microsoft 365 Copilot: agents with licence-dependent extensibility. [23][26][87][89] Agent authoring, grounding on organizational data and enhanced capabilities can require a Microsoft 365 Copilot licence, Copilot Studio or pay-as-you-go billing. Admin settings can impose additional limits. |
| Hosting and data region | Microsoft 365 Copilot: EU commitments with exceptions. [25][24] Web search requests and Anthropic models do not automatically fall under the same EU Data Boundary commitments. Germany-only hosting is not established by this source. |
| Model training | Microsoft 365 Copilot: no foundation-model training according to Microsoft. [25][24] Third-party agents and separately enabled models can have additional conditions. Configuration remains important. |
| Pricing structure | Microsoft 365 Copilot: check base licence and additional usage. [26][23] toolindex has not verified a specific regional euro price with contract term in this research. Existing Microsoft 365 cost and additional usage should be recorded separately. |
| API and development | Microsoft 365 Copilot: dedicated extensibility and API stack. [87][89] A Microsoft 365 Copilot user licence does not automatically establish access to every API, agent or Copilot Studio capability. Licence, development environment, tenant settings and any usage-based billing must be assessed separately. |

When should a company evaluate Microsoft 365 Copilot?
Microsoft 365 Copilot connects AI capabilities with Microsoft 365 applications and organisation data through Microsoft Graph. Scope depends on the licence. [23][25]
Interpretation and limitation: Microsoft now also uses the name Microsoft Copilot for the offer. This page concerns the business offer, not consumer Copilot.
Source checked: · Not hands-on tested
Microsoft 365 Copilot is embedded in Microsoft 365 applications and can be extended through Copilot connectors and agents. Microsoft explicitly documents MCP apps as MCP server-based actions in declarative agents that run inside Microsoft 365 Copilot. [23][88][89]
Interpretation and limitation: MCP apps are an extensibility path through declarative agents, not a universal entitlement of every Microsoft 365 user licence. Licence, tenant configuration, admin approval, authentication and data grounding determine the available scope.
Source checked: · Not hands-on tested
Microsoft 365 Copilot is particularly relevant when the core value should appear directly in existing Microsoft 365 workflows. Alternatives should be measured against that exact workflow rather than only against a generic chat demo. [23][25][88][89]
Provider profile · Decision context
Does Microsoft 365 Copilot support more than one model provider?
Microsoft 365 Copilot supports model choice and, in designated offers, Anthropic models. [23][24]
Interpretation and limitation: Anthropic is not enabled by default in the EU, EFTA and UK and is currently outside the EU Data Boundary. Individual models have additional conditions.
Source checked: · Not hands-on tested
Microsoft documents model choice and certain Anthropic options. This does not mean every model path has identical activation and EU data conditions. [23][24]
Provider profile · Decision context
How does Microsoft 365 Copilot use company knowledge?
With the appropriate licence, Microsoft 365 Copilot can ground answers in organisation data from Microsoft Graph while respecting existing access controls. [23][26]
Interpretation and limitation: Copilot Chat without the relevant licence scope is not equivalent to automatic access to all company data.
Source checked: · Not hands-on tested
Microsoft Graph and existing permissions are central to the work context. The quality of the starting permissions therefore needs to be part of the AI pilot. [23][26]
Provider profile · Decision context
Which governance and administration does Microsoft 365 Copilot use?
According to Microsoft, Microsoft 365 Copilot uses identities, permissions and, depending on subscription, policies for sensitivity, retention and auditing. [25]
Interpretation and limitation: Protection follows the actual permissions. Over-broad source access is not automatically fixed by AI.
Source checked: · Not hands-on tested
Microsoft 365 Copilot is managed through licence assignment and Copilot administration settings in the Microsoft environment. [26][23]
Interpretation and limitation: Existing Microsoft licences are a starting point, not proof of every Copilot capability.
Source checked: · Not hands-on tested
Microsoft 365 Copilot builds on Microsoft identities, licence assignment, permissions and, depending on subscription, sensitivity, retention and audit controls. [25][26][23]
Provider profile · Decision context
How should agents and Copilot Studio be assessed?
Microsoft 365 Copilot supports declarative and other agent paths. Microsoft also documents Copilot Studio for custom agents and actions; the available scope depends on licensing, billing model and tenant configuration. [23][26][87][89]
Interpretation and limitation: Agent authoring, grounding on organizational data and enhanced capabilities can require a Microsoft 365 Copilot licence, Copilot Studio or pay-as-you-go billing. Admin settings can impose additional limits.
Source checked: · Not hands-on tested
Microsoft documents a dedicated Microsoft 365 Copilot extensibility stack with agents, connectors, plugins, Microsoft 365 Copilot APIs and developer tools. These developer paths should be separated from standard Copilot use inside Office applications. [87][89]
Interpretation and limitation: A Microsoft 365 Copilot user licence does not automatically establish access to every API, agent or Copilot Studio capability. Licence, development environment, tenant settings and any usage-based billing must be assessed separately.
Source checked: · Not hands-on tested
Agent capabilities exist in the Copilot environment, while Copilot Studio is a separate product area for custom agents and business processes. Scope and additional usage cost should be separated. [23][26][87][89]
Provider profile · Decision context
What should companies review about Microsoft 365 Copilot hosting, privacy and security?
Microsoft documents the EU Data Boundary for its business Copilot offer and names specific exceptions. [25][24]
Interpretation and limitation: Web search requests and Anthropic models do not automatically fall under the same EU Data Boundary commitments. Germany-only hosting is not established by this source.
Source checked: · Not hands-on tested
Microsoft states that prompts, responses and Microsoft Graph data used by its business Copilot offer are not used to train foundation models. [25][24]
Interpretation and limitation: Third-party agents and separately enabled models can have additional conditions. Configuration remains important.
Source checked: · Not hands-on tested
Microsoft 365 Copilot supports model choice and, in designated offers, Anthropic models. [23][24]
Interpretation and limitation: Anthropic is not enabled by default in the EU, EFTA and UK and is currently outside the EU Data Boundary. Individual models have additional conditions.
Source checked: · Not hands-on tested
Microsoft documents a multilayered defense-in-depth approach for Microsoft Copilot, inheritance of Microsoft 365 identity and access controls, permission-bound data access, and DLP, oversharing and security-dashboard capabilities for monitoring AI-related risk. [79][25]
Interpretation and limitation: Copilot inherits existing permissions and therefore does not automatically repair content that is already overshared. Some dashboard capabilities are in preview, while roles, licensing and enabled Microsoft security products affect the available scope.
Source checked: · Not hands-on tested
Microsoft documents EU Data Boundary commitments and specific exceptions. Web search and Anthropic model use must not be assumed to have identical EU processing conditions. [25][24][23][79]
Provider profile · Decision context
How should Microsoft 365 Copilot cost be assessed?
Microsoft 365 Copilot is offered with licence prerequisites and different feature scopes. Additional agent use can be billed separately. [26][23]
Interpretation and limitation: toolindex has not verified a specific regional euro price with contract term in this research. Existing Microsoft 365 cost and additional usage should be recorded separately.
Source checked: · Not hands-on tested
Record licence prerequisites, the Copilot licence and any additional agent or Studio usage separately. toolindex has not verified one universal regional euro price for this comparison. [26][23]

What should a Microsoft 365 Copilot pilot prove?
Test the actual Word, Outlook, Teams and Microsoft Graph workflows that matter to the organisation, then compare the result with the same business outcome in alternative platforms.
- Use the same real tasks and source documents across all candidates.
- Test at least two user roles with different permissions.
- Record time to a usable result, corrections, failures and operational effort.
- Capture licence, usage, implementation and administration cost separately.
